A presentation on tidal current & it’s mechanism
This document presents information on tidal currents and their mechanism at the mouth of an estuary. It defines an estuary and explains that tidal currents are horizontal water movements caused by the gravitational pull of the moon and sun during tidal changes. At the mouth of an estuary, tidal currents are strongest where salinity matches the adjacent sea. The tidal current pushes river water back up the estuary, and the penetration of salt depends on the relative volumes of salt and fresh water. If salt water volume is much greater, a salinity wedge will form, but if freshwater volume is greater, the fresh water will flow over the salt water in two distinct layers.

The document discusses various topics related to the water cycle and water on Earth. It explains that fresh water makes up only 3% of the total water on Earth, yet humans use 1% of available fresh water. It also describes the water cycle process whereby water evaporates from lakes and oceans into the air, forms clouds, and falls back to Earth as rain or snow. Additionally, it discusses topics like ground water, glaciers, oceans, currents and tides, waves, and how human activities like pollution and deforestation impact water.
Ermia hidayanti xii ipa 3
The document explains the water cycle process in three steps:
1. Evaporation and transpiration occur as the sun heats water in oceans, lakes, and rivers, turning it into vapor that rises into the air. Plants also release water vapor through transpiration.
2. As the water vapor rises, condensation occurs where it cools and condenses into clouds.
3. Precipitation falls from clouds as rain, snow, or hail and runs off into streams and rivers, eventually flowing back into oceans, completing the cycle. Pollution can disrupt this natural cycle, so proper waste disposal is important to maintain it.
The Water Cycle Diapositiva Grecia14 Lagrimas Del Celo
The water cycle involves the constant circulation and recycling of Earth's water supply over billions of years. Water evaporates from the oceans into the atmosphere due to solar heat, forming clouds. Clouds release water as rain or snow onto land and oceans when conditions are right. Rivers and currents return water from the soil to the oceans, completing the cycle as salty ocean water takes fresh water back to the continents once more. Human contamination of the environment could disrupt this important hydrological cycle and negatively impact future generations if water resources are not properly managed and conserved.

The document discusses various topics related to water including its composition, the water cycle, ocean topography, ocean currents and tides, and how humans affect water. It notes that water is essential to life, the majority of Earth and the human body is made of water, and water is recycled through evaporation and precipitation. Less than 1% of water on Earth is drinkable.
6th Grade Chapter 16- water cycle
The document discusses the water cycle and various components of Earth's hydrosphere. It explains that water evaporates from bodies of water due to the sun's energy, rises into the atmosphere as vapor, cools and condenses to form clouds, and falls back to Earth as precipitation. The cycle involves surface water runoff into streams, rivers and oceans. Groundwater is water that soaks into the ground and collects in soil and rock pores. Tides are caused by the gravitational pull of the moon and sun, forming bulges in the oceans.
The water cycle
The document discusses the water cycle and its 9 key stages: evaporation, condensation, precipitation, interception, infiltration, percolation, transpiration, runoff, and storage. It explains each stage in detail, specifically how water changes between liquid, gas, and solid states, and how it moves between the atmosphere, land, and bodies of water. The water cycle is critical because it replenishes our water supply, supports ecosystems, and influences our access to clean water for drinking and other uses.
Kathleen's Powerpoint Presentation in Sir Rey's Computer Class
Rivers form through the natural process of water runoff from land surfaces collecting in low areas and eroding channels over time. As runoff from multiple slopes combines, it increases the water's eroding power to form gullies that eventually develop into full valleys containing a permanent stream, along with tributaries that feed into the growing river system within the watershed.

As runoff from multiple slopes combines, it increases the water's eroding power to form gullies that eventually develop into full valleys containing a permanent stream, along with tributaries that feed into the growing river system within the watershed.
Climate
The document discusses how bodies of water influence climate. Water has a higher heat capacity than air, so it takes longer for water to heat up and cool down. During the day, water bodies absorb heat from the sun, and then slowly release that heat overnight and in winter, keeping surrounding areas warmer. Ocean currents also affect climate by transporting water—and the temperatures associated with its origin—to other regions.
Explanation watercycle
The water cycle describes the continuous movement of water on, above, and below the surface of the Earth. Water evaporates from bodies of water into the air due to heat from the sun, condenses to form clouds, and falls back to Earth as precipitation. This cycle is crucial as it provides fresh water for living organisms and sustains life on the planet.
Water cycle
The document summarizes the water cycle through evaporation, condensation, and precipitation. It explains that water evaporates from bodies of water and becomes water vapor in the atmosphere. The water vapor then condenses to form clouds and precipitation like rain or snow. Precipitation falls back to the ground and bodies of water, completing the cycle.
Water forms
The document discusses the major forms of water on Earth. It describes the five oceans which cover 70.8% of the planet's surface: Pacific, Atlantic, Indian, Antarctic, and Arctic. It also discusses seas, which are large bodies of water almost completely surrounded by land like the Mediterranean. Other forms discussed include lakes, rivers, gulfs, bays, straits, canals, and the world's longest rivers. The document provides locations and other key details about major examples of each water form.
Cycle of rain
The water cycle describes how water is constantly recycled through the atmosphere, oceans, and land. Energy from the sun drives this process by heating water which evaporates from bodies of water and soil into the atmosphere. Plants also release water vapor through transpiration. As the water vapor rises, it cools and condenses to form clouds. When clouds become too heavy, the water falls back to Earth as precipitation in the form of rain or snow. The precipitation is absorbed into the ground, collects in streams and rivers, and eventually returns to the oceans to continue the cycle again. The water cycle is essential for sustaining life on Earth.
The Water Cycle
The water cycle describes the continuous movement of water on, above, and below the Earth's surface. Water can exist as a solid, liquid, and gas and is constantly changing forms as it moves through this cyclic process. The sun provides energy for evaporation and precipitation to occur as water circulates between bodies such as oceans, atmosphere, and land through processes like evaporation, condensation, precipitation, and runoff. This cycle is crucial as it replenishes and purifies the water supply on Earth.
Unit 8 water on earth
The earth is made up of water, land, and an atmosphere. Water exists in three states - solid, liquid, and gas. It is the most abundant component on earth and is essential for most living things. Water can be found in oceans, seas, rivers, lakes, clouds, underground, and as water vapor in the air as part of the continuous water cycle.
Chapter 15-atmosphere
The document summarizes key aspects of Earth's atmosphere. It describes the atmosphere as a thin layer of air that protects the planet and maintains a balance of absorbed and emitted heat. The atmosphere is made up primarily of nitrogen and oxygen but originally contained more carbon dioxide. Over time, oxygen increased through photosynthesis while other layers like the ozone layer developed. The atmosphere has lower layers like the troposphere where weather occurs and upper layers that absorb sunlight. Gases in the atmosphere contribute to pressure and temperature variations and the protective ozone layer.
Rainwater
Rainwater is the primary source of fresh water globally and provides suitable conditions for diverse ecosystems. It also enables hydroelectric power and plant/crop irrigation. Rainwater contains salt, water, nitric acid, sulfuric acid, and carbon. It goes through the hydrological cycle of evaporation, condensation, precipitation, and infiltration/runoff. Evaporation turns water into vapor which rises and condenses into clouds. Rain falls from clouds through precipitation and infiltrates the ground or runs off via rivers/lakes back to the oceans to complete the cycle.
Water Cycle Powerpoint
The document summarizes the water cycle, which is driven by energy from the sun. Water is constantly being cycled through evaporation, condensation, and precipitation between the atmosphere, ocean, and land. Evaporated water rises into the atmosphere, cools and condenses to form clouds, then falls back to earth as precipitation, with some absorbed into groundwater and running into streams and rivers as runoff, completing the cycle.
Monday may 2 water on earth powerpoint
This document discusses the water cycle and where water is found on Earth. It explains that water is essential for humans, plants and animals. The water cycle involves evaporation of water from oceans, soil and other sources, which condenses into clouds and returns to Earth as precipitation like rain or snow. Some precipitation runs off and some soaks into the ground to become groundwater. Most fresh water on Earth's surface is found in rivers, lakes, and as groundwater or glacial ice. The water cycle continuously circulates the planet's water supply.
THE HYDROSPHERE
The document discusses the hydrosphere and water cycle on Earth. It describes how water circulates between the oceans, atmosphere, and land via evaporation, condensation, and precipitation in the water cycle. It provides details on the distribution of water on Earth, including that 97.5% is salt water in oceans and seas while the remaining 2.5% is fresh water in ice caps, glaciers, inland water, and groundwater. Rivers, lakes, and oceans are described along with their characteristics and locations.
Water Cycle[1] Power Point
The water cycle describes the continuous movement of water on, above, and below the surface of the Earth. The sun warms water in oceans and lakes, causing it to evaporate into water vapor in the air. Water vapor condenses to form clouds, and air currents move clouds around the world. When clouds become too full, water falls as precipitation like rain or snow. Precipitation returns to oceans, lakes, and rivers, where the cycle repeats.
Water cycle
The document describes the water cycle, where water evaporates from oceans, rivers and land into water vapor due to heat from the sun. The vapor rises into the sky where it cools and condenses into clouds. The clouds become heavy with water and precipitate as rain, snow, or hail back down to land and bodies of water, completing the cycle as the water runs back into oceans and seas or soaks into the ground.

Chapter 18 & 19- ocean
1) The oceans are important sources of food, energy, minerals, and allow for transportation. They formed from water vapor in the atmosphere condensing over millions of years.
2) The oceans contain dissolved gases, salts, and other elements. Desalination plants remove salt from seawater to produce freshwater.
3) Ocean currents are large masses of water that circulate horizontally, powered by winds, and move different water temperatures in different directions around the globe.
River Rejuvenation VLE
Rivers over long periods of time develop a smooth, concave long profile as they adjust their characteristics to transport water and sediment in a state of dynamic equilibrium with their environment. However, occasional events can destabilize this equilibrium, increasing the river's energy and causing it to actively erode its channel to reestablish its optimal long profile through a process called rejuvenation. Common causes of rejuvenation include changes in base level from tectonic uplift or changes in sea level. During rejuvenation, landforms such as waterfalls from knickpoints, incised meanders, and river terraces may form as the river adjusts to its new gradient.

Groundwater movement and the formation of wells, springs, caves, sinkholes and geysers are also summarized briefly.
Mm
Water covers 78% of the Earth's surface. The moon's gravity causes ocean waves and tides. The water cycle involves evaporation of water from the sun into clouds, precipitation of rain from clouds, and repetition of the cycle. The ocean subsurface contains underwater landforms like mountains and hills. Ocean currents and tides move water and create waves, while rip tides can pull sandbars inward. Humans negatively impact oceans through pollution and damage to fish populations.
Bm
The document discusses various topics related to freshwater and saltwater habitats on Earth. It describes how fresh water makes up a small percentage of the total water on Earth, found in lakes, ponds, rivers and streams. It also discusses the water cycle, how water is constantly recycled from clouds to ground and back again. Finally, it touches on how human activities like pollution can negatively impact water quality in oceans.
Oceanic currents
The document provides information about ocean currents, including:
1) The global conveyor belt involves cold, salty water sinking in the North Atlantic and circulating in a deep ocean current around the world before rising again in other ocean basins and looping back to the North Atlantic.
2) Ocean currents can be classified based on depth as surface currents in the top 400m or deep water currents that circulate deeper due to density variations.
3) El Niño involves unusually warm waters in the eastern Pacific affecting global weather, while La Niña has below-average temperatures in that region with opposite weather impacts.

Water is a chemical substance with the formula H2O that can exist as a solid, liquid, or gas. It is transparent and allows sunlight to reach aquatic plants and is the major component of cells. The water cycle is driven by the sun and involves evaporation, condensation, precipitation, runoff, infiltration, groundwater discharge and springs. Ocean surface topography varies in a similar way to land topography and influences ocean currents, heat transport, and sea level changes. Tides are caused by gravitational forces from the moon and sun, resulting in two high and two low tides daily in most coastal areas. Human pollution and development are deteriorating ocean ecosystems.
Tmu
Water cycles through evaporation and rain, keeping lakes, rivers, and oceans full to hydrate plants, animals, and humans. It rains, evaporates, and the cycle repeats, with water helping lives through hydration. Ocean landforms include coral reefs, while currents and tides are also featured in the water section, along with the problems of littering in water bodies.

This document summarizes Neil Jensen's final water project. It covers various topics about water including its properties, ocean sediments, ocean ooze, the water cycle, ocean topography, tides and currents, and how humans affect water. The water cycle replenishes water through evaporation, condensation, precipitation, and runoff. Ocean sediments come from eroded land rocks, volcanoes, and space dust. Ooze covers 30% of the ocean surface and is made of organic remains and liquids mixed with other materials. Humans negatively affect water through waste dumping and oil spills.
Sw
Water is a substance known as H2O that is essential for life and found all over Earth, including in oceans, lakes, rivers, and homes. It is needed by all animals and humans to survive and is also used by astronauts in training despite being found in various forms like waterfalls, lakes, or flowing through homes.
Cw
People affect water through waste production and pollution, as well as by water treatment. Waste and pollution impact water quality, while water treatment aims to clean water for safe use. The short video discusses how human activities can influence water resources, both negatively through waste and pollution, and positively through treatment efforts.
Ep
The document discusses various topics related to water including its importance, the water cycle, the ocean, currents and tides, and how humans affect water. It notes that water is essential for life but only 1% of the total water is available for human use. The water cycle involves processes like evaporation and condensation that move water from the clouds to the ocean and around the world. The ocean contains a vast amount of life but its water is salty and unsuitable for drinking. Currents and tides are caused by various natural factors and can be dangerous, while human waste is polluting the ocean and harming sea life.
Tt
Fresh water is found in lakes and rivers while salt water is found in oceans and some lakes. The water cycle involves evaporation and condensation of water. Land forms near oceans include continental shelves, slopes, and trenches. Tides are caused by gravity pulling water up and down as the Earth rotates while currents involve strong flows of water. People negatively impact water through oil spills, littering, and pollution from factories.
Bn
Water is essential for human survival and all life on Earth. It is necessary for drinking, growing plants and trees, and participating in natural water cycles. The water cycle involves rain falling from the sky, collecting in lakes and oceans, evaporating into vapor, and starting the process again. Humans can help sustain the water cycle by conserving and reusing water. Water also supports underwater ecosystems and undiscovered shipwrecks.
Hb
This document discusses various topics related to water, including fresh water, salt water, the water cycle, ocean topography, currents and tides, and how humans affect water. It notes that most fresh water is found in Arctic ice, fresh water can be reused, and salt water can be made fresh through boiling. The water cycle is described as important because it allows water to be used repeatedly without running out. The ocean bottom contains diverse life even in very deep and dark areas, while currents and tides are influenced by the moon and sun. Humans can negatively impact water but also reuse it; reducing water usage and properly disposing of trash can help address these effects.
Cn
The water cycle involves water evaporating from surfaces like pavements into clouds due to heat from the sun, then condensing in the clouds and falling as rain which feeds plants. Ocean landforms are varied with hills, plains and mountains under the water similar to land formations. Fresh water is found in lakes, rivers and puddles while being non-salty, and salt water is only in the oceans and polar regions, becoming saltier near the equator. Tides are caused by the moon's gravitational pull leading to the regular rising and falling of sea waters. Humans both utilize water for drinking but also waste large amounts through activities like car washing and taking long baths.
Am
The document discusses the global water cycle and distribution of water on Earth. Most of Earth's water is salt water located in oceans, while only 2% is fresh water found in lakes, rivers, and underground aquifers. The water cycle involves evaporation of water from bodies of water into clouds, which condenses and falls as precipitation back to Earth. Humans have significantly impacted water through use for agriculture, industry, trade, and more, with 2/3 of the population dependent on fish and water used for power generation and transportation.
