motion of earth
The document discusses the motions of the Earth, including its rotation and revolution. The Earth rotates once every 24 hours on its axis, and revolves around the sun once every 365.25 days in its orbit. The Earth's axis is tilted at an angle of 661⁄2 degrees from its orbital plane. The circle of illumination is the imaginary line that separates day and night, experiencing sunshine.
The movements of the earth flavia
1) The Earth rotates on its axis from east to west and revolves around the Sun in an elliptical orbit over 365 days.
2) A leap year, like 2012, adds an extra day every four years to keep the calendar aligned with the solar year which is actually 365.25 days.
3) The changing of seasons is caused by the tilt of the Earth's axis as it revolves around the Sun over the course of the year.
Earth's movemments power point rafi
The earth has two movements: rotation, which is its daily motion on its axis completing every 24 hours and causing day and night, and revolution, which is its elliptical orbit around the sun over the course of a year (365 1/4 days) causing the four seasons and changing distance between the earth and sun. Leap years have an extra day in February to account for the quarter day difference between the calendar year and solar year.
Basic Geography
The document discusses the motions and major divisions of the Earth. It describes how the Earth rotates on its axis once every 24 hours, causing the cycle of day and night. It also revolves around the sun once every 365 days. The document outlines the Equator and important latitudes and longitude lines that divide the Earth, such as the Tropic of Cancer and Prime Meridian. It explains phenomena related to day and night, such as varying day length depending on location and season, as well as different timekeeping systems used worldwide.
The motion of Earth
1) The Earth rotates on its axis daily, causing the apparent motion of the sun, moon, and stars across the sky from east to west.
2) The Earth also revolves around the sun yearly, leading to seasons and variations in the sun's path.
3) Additionally, the Earth's axis undergoes a slow wobble called precession and a nodding motion called nutation, along with variations in its rotation.
Moon earth sun
The document discusses the relationships between the Earth, moon, and sun. It explains that the moon's rotation is synchronized such that the same side always faces Earth. The moon affects Earth's tides and orbital motion. While the sun gravitationally influences Earth and the moon as a single system, Earth's elliptical orbit and changing rotation rate mean the sun's position is not uniform from Earth's perspective. Therefore, mean solar time uses a theoretical mean sun point that moves at a constant rate instead of the real sun's position.
Earths movement-rotation-vs-revolution-powerpoint-english
The document discusses the Earth's rotation and revolution in space. It explains that the Earth rotates on its axis once every 24 hours, causing day and night, and revolves around the Sun once every 365.25 days, creating the seasons. The tilt of the Earth's axis combined with its revolution is what causes the seasons in both the northern and southern hemispheres.

Sun, earth & moon gr 3
The document discusses the Sun, Earth, and Moon. The Sun is a big ball of gases that is the source of all energy. It takes 8.4 minutes for light from the Sun to reach Earth. The Earth orbits the Sun and is the only planet that supports life. The Moon orbits the Earth and reflects light from the Sun, taking 28 days to revolve around the Earth. Day and night on Earth occur due to its rotation, while the year occurs due to its revolution around the Sun.
Phases of the Moon
The document discusses the phases of the moon. It explains that the moon gets its light from the sun and revolves around the earth every 28-31 days. As it revolves, the shape of the moon changes through phases such as new moon, crescent moon, quarter moon, gibbous moon, and full moon depending on how much of the illuminated side is visible to observers on earth.
Earth in space
The document discusses the causes of seasons and other earth movements. The seasons change because of the tilt of Earth's axis, not its distance from the sun, with the northern and southern hemispheres experiencing summer and winter respectively as Earth rotates. Earth's rotation on its axis causes day and night as the sun appears to move across the sky from east to west. Earth's revolution around the sun, which takes one year to complete, is different than its rotation. Calendars were developed to organize time based on Earth's motions and those of the moon.

Tides are caused by the gravitational pull of the moon and sun and the rotation of the Earth. The moon's gravity pulls the ocean waters closest to it, creating high tides, while the furthest waters experience low tides. Spring tides occur when the sun, moon, and Earth are aligned, producing the largest difference between high and low tides, while neap tides happen at a right angle and have smaller tidal ranges.
Mouse mischief tides
The tides are caused by the gravitational pull of the moon. This creates two bulges in the Earth's oceans, one on the side facing the moon and one on the opposite side. As the Earth rotates daily and the moon orbits around it monthly, different locations experience high and low tides at different times over the course of approximately 25 hours. This cycle explains why there are two high tides and two low tides each day.
Revolution rotation seasons short 2012
The document discusses the rotation and revolution of the Earth and how it causes seasons. It explains that the Earth rotates daily on its tilted axis, causing day and night. It revolves around the sun yearly, and the tilt of its axis relative to its revolution around the sun causes the seasons in the Northern and Southern Hemispheres. When the Northern Hemisphere is tilted toward the sun, it experiences summer, and when tilted away, it experiences winter.

Lab six earth and sun relationships
The document discusses Earth's relationship with the Sun. It explains that Earth revolves around the Sun in an elliptical orbit over the course of 1 year, and rotates on its axis over the course of 1 day. Due to Earth's axial tilt of 23.5 degrees and its revolution around the Sun, the Sun's rays strike different parts of Earth at different angles over the course of the year, causing the seasons. An analemma diagram can be used to determine the position of the subsolar point and solar altitude for any location on Earth on a given date.
Sun & moon cycles (big teach)
This document discusses cycles related to the movement of objects in the solar system. It explains that the Earth revolving around the sun causes years, while the Earth rotating on its tilted axis and orbiting the sun together cause the four seasons - summer, fall, winter, spring. The moon orbiting the Earth causes moon phases, and the moon's gravity pulling on Earth's oceans causes two high and two low tides each day.
Unit 1. Planet Earth
The document discusses the Earth's imaginary lines, movements, seasons, and layers. It describes how meridians run vertically between the North and South Poles in degrees east or west, while parallels run horizontally around the Earth in degrees north or south. It also explains that the Earth revolves around the Sun over 365 days, causing seasons to differ between hemispheres as its tilted axis results in varying sunlight. Finally, it outlines the Earth's main layers as the atmosphere, hydrosphere, and geosphere.

The document is a PowerPoint presentation about tides. It introduces tides as the periodic rising and falling of sea levels caused by the gravitational pull of the moon and centrifugal force. There are two types of tides described: spring tides, which occur when the sun and moon are aligned and exert maximum gravitational pull, causing exceptionally high tides; and neap tides, which occur when the sun and moon are at a 90 degree angle, pulling in opposite directions and resulting in very low tides. The document concludes by explaining that tides are caused by the combined gravitational forces of the moon and sun along with the Earth's rotation, and can vary in type and timing in different locations.
earthquakes
Earthquakes are caused by the sudden release of energy from the breaking of rocks deep in the earth. The elastic rebound theory explains how stress builds up in rocks until it exceeds the rocks' strength, causing rupture and the release of seismic waves. The focus is the point where faulting begins underground, and the epicenter is the point directly above on the surface. Most earthquakes occur along plate boundaries and are mapped using seismic wave arrival times at multiple stations. Earthquake size is measured by both intensity scales based on damage, and by magnitude scales measuring the total energy released.
Weather.climate edited
Weather refers to short-term atmospheric conditions in a small area that can change rapidly, while climate describes long-term patterns over 100+ years in a large area that changes very slowly. Seasons are caused by the tilt of the Earth's axis of rotation relative to its orbit around the sun, which determines how direct sunlight strikes each hemisphere over the course of a year. The summer solstice marks the longest day of the year when the sun's rays are most direct, while the winter solstice is the shortest day with the most indirect sunlight.
Earth`s patterns
1) Earth spins on its axis once every 24 hours, causing day and night. The side of Earth facing the sun experiences day, while the opposite side experiences night.
2) Earth also revolves around the sun once every year. As it revolves, its tilted axis remains pointed in the same direction, causing seasons.
3) The tilt of Earth's axis and its revolution around the sun cause the four seasons - spring, summer, fall, and winter - in the northern and southern hemispheres.
Air, Water, And Solar Energy
The document defines key terms related to Earth's geography, climate, and weather patterns. It describes the Arctic and Antarctic Circles, Tropics of Cancer and Capricorn, and how they relate to the sun's zenith at different times of year. It also defines the polar, temperate, and tropical zones and explains ocean currents, the Coriolis effect, prevailing westerlies, jet streams, gyres, upwelling, El Niño, and air masses.
Milancovitch cycles
The document summarizes Milutin Milanković's theory that variations in the Earth's orbit and axial tilt (known as Milankovitch cycles) influence long-term climate changes by affecting the amount of solar radiation reaching the Earth. These cycles are caused by changes in the Earth's eccentricity, obliquity, and precession over thousands to hundreds of thousands of years. Lower summer insolation in the Northern Hemisphere due to these orbital variations can trigger ice ages by preventing summer melting of winter snows and ice accumulation. Stratigraphic evidence from oxygen isotopes and fossils correlates past climate changes with Milankovitch cycle patterns.
Time zones
The document discusses time zones and how they were established. It explains that in 1884, the Prime Meridian passing through Greenwich Observatory in London was adopted as the international standard meridian. The world was divided into 24 time zones, each corresponding to 15 degrees of longitude and 1 hour. Greenwich Mean Time (GMT) was established as the universal day beginning at midnight on the Prime Meridian. This system allows different regions of the world to use coordinated time zones despite varying sunrise/sunset times due to the Earth's rotation.
Suramya
The document discusses the greenhouse effect and the gases that cause it. It explains that greenhouse gases like carbon dioxide and methane in the atmosphere trap infrared radiation reflected from the Earth's surface, preventing it from escaping into space and warming the planet. These gases are emitted through processes like burning fossil fuels, agriculture like rice cultivation and livestock grazing, and decay from landfills. The greenhouse effect is what determines the surface temperatures of planets like Earth and Venus by modifying the radiative equilibrium through their atmospheric compositions.

Class6 Earth Rotation And Revolution
The document discusses the two motions of the Earth: rotation and revolution. It notes that rotation is the Earth spinning on its axis once every 24 hours, which causes day and night. Revolution is the Earth orbiting the Sun in an elliptical orbit, taking 365 days to complete one revolution and causing the seasons due to changes in distance from the Sun throughout the year. The rotation of the Earth occurs at approximately 15 degrees per hour and spins at over 1600 km/hr at the equator.

The Earth has two movements: rotation and revolution. Rotation is the Earth spinning on its axis every 24 hours, causing day and night. Revolution is the Earth orbiting the Sun every 365 days, causing seasons and years. Due to these movements, different parts of the Earth receive varying amounts of sunlight, influencing climate zones and seasons. The tilt of the Earth's axis and its position in orbit also affect the length of daylight and temperature changes throughout the year.

The document discusses latitudes and longitudes on a globe. It describes how the globe is tilted on its axis with the North and South poles. It discusses the equator line and parallels of latitude that run parallel to it. Important parallels mentioned include the Tropic of Cancer, Tropic of Capricorn, Arctic Circle, and Antarctic Circle. It also discusses longitude lines and the Prime Meridian that passes through Greenwich, England. Time zones are based on longitude, with places east of the Prime Meridian being ahead in time and places west being behind.
Earth's motion 3
The document summarizes key concepts about the Earth's motion, including its rotation on its axis daily and revolution around the sun yearly. It describes how rotation causes day and night and affects the Earth's speed at different latitudes. Revolution is defined as the Earth's elliptical orbit around the sun, taking 365 days to complete. Seasons and solstices/equinoxes are explained in relation to the tilt of the Earth's axis. Other geographic concepts like latitude, longitude, the International Date Line and Prime Meridian are also briefly outlined.
The movements of the Earth
The Earth moves in two ways: by rotating on its axis daily, and by revolving around the Sun yearly. The Earth's tilted axis and oval-shaped orbit cause the seasons by changing the angle and duration of sunlight received in different parts of the world throughout the year. The rotation of the Earth causes day and night, and the revolution around the Sun in 365 days causes the four seasons as the Earth's positioning shifts solstices and equinoxes.

The document describes several motions and characteristics of Earth:
- Earth orbits the Sun in an elliptical path and rotates daily on its tilted axis, causing seasons and different day lengths at different times of year.
- Earth's shape is an oblate spheroid with a bulge at the equator, and its orientation and motions cause the seasons in the Northern and Southern Hemispheres.
- Locations on Earth are specified using a grid of lines of latitude and longitude referenced to the equator and Prime Meridian. Time is measured using solar days, years, and calendars accounting for Earth's orbital period.
An introduction to earth rotation and revolution
The document discusses Earth's rotation and revolution. Earth's rotation refers to its spinning on its axis once every 24 hours, causing day and night and influencing tides, wind speed, and direction. Earth's revolution is its orbit around the sun, taking 365.25 days to complete one year. The results of revolution include seasonal variations due to changes in the Earth's position relative to the sun throughout the year, as well as solstices, equinoxes, and opposite seasons between the northern and southern hemispheres.
Earth Rotation (MUHAMMAD NAUMAN)
The Earth rotates on its axis once every 24 hours. This rotation causes day and night and is important for establishing geographic coordinates and time zones. The Earth also revolves around the Sun once every 365.242 days. This solar orbit is responsible for seasons and the amount of daylight, due to changes in the Earth's position relative to the Sun throughout the year. Key points in this orbit include perihelion, when the Earth is closest to the Sun, aphelion, when it is farthest, and the equinoxes and solstices, which affect daylight hours in the different hemispheres.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

- 5. Power point presentation on " earth's axis, rotation and revolution and its effects".
- 6. Earth's rotation Earth's rotation is the rotation of the solid earth around it's own axis. The earth rotates from the west towards the east, or from left to right. The earth rotates ones in about 24 hours with respect to the sun. The earth's rotation is the reason for changing day and night.
- 7. Earth's revolution The earth travels once around the sun, it is considered as revolution on earth. A revolution is quite a bit longer - one year! The earth orbits the sun( its revolution) ones every 365 days, 6 hours and 9 minutes. The extra quarter day creates a 366th calendar day in leap years.
- 8. The axis The axis of rotation is an imaginary line going from the north pole to the south pole. The earth turns all the way around or spins on its axis one time.
- 9. Time zones The world is a sphere. As the sun shines on different places on the spare, the other side will be in shadow. This means that on one side of the world it is noon, and on the other, it is midnight, creating 24 different 24 time zones with 15 degree of longitude wide.
- 10. Longitudes It is an angular measurement, usually expressed in degrees. Longitude is defined in terms of meridians, which are half circles running from pole to pole. Longitude angles can range up to +180 degrees (180 degree east) and down to - 180 degrees (180 degree west).
- 11. Latitudes Latitude is defined with respect to an equatorial reference plane. This plane passes through the center of the sphere, and also contains the great circle representing the equator. Latitude angles can range up to +90 degrees (or 90 degrees north) and down to -90 degrees ( or 90 degrees south)
- 12. Seasonal variations Earth's revolution is the main reason for the seasonal variations of the earth. Every place on earth experiences seasonal variations. Because of the direction of the tilt changes in rotation to the sun, the northern and southern halves of our planet experiences different seasons like summer, winter, autumn etc.
