I. b. earth and earth systems
The document discusses the different spheres or layers of the Earth. It begins by describing the Earth and its color compared to other planets. It then discusses the four subsystems that make up Earth and flow of matter and energy between them. It identifies the layers of the Earth and differentiates between them. Finally, it discusses natural waters and the water cycle.
The earth's four spheres
The surface of the earth is divided into four inter-connected spheres called "geo-spheres". These are the lithosphere, hydrosphere, biosphere, and atmosphere. Geologists, scientists and researchers discovered and classified life and material on or near the surface of the earth in these four spheres. The four spheres derived its names from the Greek words litho for stone, atmo for air, hydro for water and bio for life.
The Dynamic Earth
The document summarizes key facts about the dynamic Earth. It describes the different layers of the Earth including the crust, mantle, and core. The crust is divided into continental and oceanic crust of varying thicknesses. The mantle makes up most of the Earth's mass and is divided into lithosphere, asthenosphere, and mesosphere layers. The core is divided into a solid inner core and liquid outer core. The document also briefly outlines the Earth's rotation, revolution around the sun, and reasons for the seasons.

Origin of earth
This slide describes various theories about origin of the earth, like nebular theory, big bang theory, etc.
Earth Systems and Resources
An overview of the Earth's systems and resources from earth science to atmosphere to water use to soil.
Geology powerpoint earth layers
The document summarizes Earth's internal structure and tectonic plate theory. It describes three main layers - the crust, mantle, and core. The crust and upper mantle make up the lithosphere which is divided into separate tectonic plates that move over the asthenosphere due to convection currents in the mantle. Plate boundaries occur where plates meet and cause volcanoes, earthquakes, and mountains through divergent, convergent and transform interactions.
Lithosphere
The document provides an overview of the structure and composition of the Earth's interior based on evidence from seismology and other studies. It describes the different layers from outer to inner as:
1) The lithosphere and crust, composed mainly of silicate rocks with densities around 3.5.
2) The mantle, extending to a depth of 2900km and divided into upper and lower zones. It has a mean density of 4.6.
3) The core, extending from 2900km to the center. It is divided into a liquid outer core and solid inner core, and has the highest densities in the Earth ranging from 10 to 13.6.
Unit 8: The Earth's internal energy
The document discusses the Earth's internal energy and how it causes tectonic plate movement and related geological phenomena. The main points are:
1) The Earth has internal heat from radioactive elements and impacts that causes plate tectonics and results in volcanoes, earthquakes, and mountain building.
2) Alfred Wegener proposed continental drift in 1912 to explain how the continents were once joined together before drifting apart, as evidenced by matching continental shelves.
3) The Earth's solid crust is made up of tectonic plates that move due to convection currents in the mantle, resulting in earthquakes and volcanic activity at plate boundaries.
Geosphere and domains of the earth
The document discusses the four major spheres of Earth - the geosphere, atmosphere, hydrosphere, and biosphere. It describes the composition and layers of the geosphere, including the crust, mantle, and core. The crust consists of different rock types and divides into continental and oceanic plates. The mantle is the largest layer and flows due to temperature differences. The core has an outer liquid layer and inner solid layer with extreme heat and pressure. The atmosphere surrounds Earth and consists of nitrogen, oxygen and other gases. The hydrosphere includes all water on the planet across oceans, ice, underground, and vapor in the air. The biosphere encompasses all living things and organic matter on the planet.
Earth’s spheres
The document summarizes the three main spheres of Earth - the atmosphere, hydrosphere, and lithosphere. The atmosphere is the thin envelope of gas, liquids, and solids surrounding Earth, held in place by gravity. It is stratified into zones with different characteristics, including the troposphere, stratosphere, mesosphere, and thermosphere. The hydrosphere covers 3/4 of Earth's surface and includes all bodies of water. The lithosphere is the most solid and continuous part of Earth, made of rock near the surface, including under the hydrosphere and accounting for mountains and faults.
THE EARTH
The Earth formed around 4.5 billion years ago. It is the third planet from the sun and the only known planet capable of sustaining life. The Earth has a molten iron core, a solid silicate mantle, and a crust consisting of tectonic plates that migrate across the surface over millions of years. The Earth's atmosphere, hydrosphere, and biosphere support around 8.7 million known species of life. Humans depend on the biosphere and minerals of the Earth, though pollution poses threats to both the environment and human health.
History and formation of the Earth (Presentation #2 Bilogy L2 project)
The Earth formed 4.54 billion years ago from a solar nebula. Its early atmosphere was toxic and volcanic activity and asteroid impacts were common. One large impact is believed to have formed the Moon. Over billions of years the planet cooled and developed tectonic plates and a stable crust allowing liquid water and the first life. The atmosphere gradually gained oxygen as photosynthetic life evolved. Multicellular life diversified in the Phanerozoic Eon starting over 500 million years ago, though many species died out in extinction events like the one that ended the Cretaceous Period.
Lithosphere
Ophiolites provide evidence for the composition and structure of oceanic crust and the upper mantle. They represent sections of oceanic crust and upper mantle that have been obducted or thrust onto continental margins. Studying ophiolites like the Samail ophiolite in Oman has helped scientists understand the layered sequence of rocks that make up oceanic crust, including extrusive basalts, dikes, and intrusive gabbros.
Shells of Earth
The document discusses the four main spheres that make up Earth's systems - the lithosphere, hydrosphere, atmosphere, and biosphere. It describes each sphere and how they interact with each other. The lithosphere is the solid rocky parts of Earth. The hydrosphere contains Earth's water. The atmosphere is the envelope of air surrounding Earth. The biosphere contains all of Earth's living things. Together, these four spheres interact to form complex Earth systems that sustain life.
Earth's spheres
The document describes the four major interacting components that make up the Earth system: the atmosphere, biosphere, hydrosphere, and geosphere. It provides details on the composition and layers of the atmosphere. It then summarizes the geosphere as the solid Earth, the biosphere as the zone supporting life, and the hydrosphere as all of Earth's water. It concludes that Earth system science studies how changes in one component can affect the others, providing examples of how the geosphere, atmosphere, hydrosphere, and biosphere interact.
Spheres of the earth
The document describes the four main spheres that make up Earth: the atmosphere, geosphere, hydrosphere, and biosphere.
The atmosphere is the layer of gases surrounding Earth, including oxygen, nitrogen, and other gases. The geosphere is the solid layer of Earth, including the continents and ocean floor. The hydrosphere consists of all water on Earth, found as liquid in oceans and ice, and as gas in the atmosphere. The biosphere is made up of all living things on Earth.
Lithosphere
The lithosphere is the rigid outer layer of the Earth that has an average thickness of 75km. It is composed of several plates that move via the process of plate tectonics. The main parts that make up the lithosphere are the crust, mantle, asthenosphere, core, and transition zone. The lithosphere is useful as it serves as a source of minerals, fuels, and supports plant and animal life, with water bodies essential for survival.
Four spheres
This document describes the four spheres that make up Earth's systems - the hydrosphere, atmosphere, geosphere, and biosphere. It provides details on each sphere, including that the hydrosphere is made up of 71% of Earth's surface as oceans and saltwater, while the atmosphere is a thin gaseous envelope composed of nitrogen, oxygen, and variable components like water vapor. The document also notes that the geosphere encompasses the solid interior of Earth from the crust to the core, and the biosphere incorporates all living things on the planet.
Earth's Spheres
The document discusses Earth's spheres which include the atmosphere, hydrosphere, lithosphere, biosphere, cryosphere, and anthroposphere. It explains that the spheres are closely interconnected, with changes in one sphere often causing chain reactions and changes in other spheres. An example is provided of a forest fire destroying plants, which leads to erosion, increased soil in water, higher turbidity, and impacts on water plants and animals, demonstrating the interactions between spheres.
The Earth’s Structure
The Earth has three main layers - a core, mantle, and crust. The crust is made up of tectonic plates that slowly move due to convection currents in the mantle. Alfred Wegener first proposed the theory of continental drift in the early 1900s, but it was not widely accepted until the 1950s when studies of the ocean floor provided supporting evidence. For the past 200 million years, the atmosphere has been around 78% nitrogen and 21% oxygen, though it was likely different in the early Earth with more carbon dioxide and less oxygen. Human activities like burning fossil fuels are increasing carbon dioxide levels today.
A View Of Earth
An introductory presentation that presents the four spheres of the Earth, as well as the Earth's four zones: lithosphere, asthenosphere, outer core, and inner core. Developed for a high school Earth Science course.
Earth subsystem
The document discusses the Earth system and its interconnected components. It describes the five layers of the ocean - the epipelagic, mesopelagic, bathypelagic, abyssopelagic, and hadalpelagic zones - and notes the unique characteristics of life in each zone. It also outlines the five spheres of the Earth system - the hydrosphere, atmosphere, lithosphere, biosphere, and anthroposphere - and how they interact as a collective whole.
Formation of earths’ geosphere
The document summarizes Earth's structure and composition. It describes that Earth has distinct layers including the crust, mantle, and core. The crust and upper mantle form Earth's lithosphere which is separated into tectonic plates. The mantle circulates heat via convection currents which drive plate tectonics. Earth's inner core is solid iron while the outer core is liquid nickel-iron alloy. Earth's magnetic field is generated by convection currents in the outer core which protects life from solar radiation.

Basic geography (graphic presentation of the earth)
Maps and globes are valuable tools for geography that show the shapes, sizes, locations, and patterns of distribution of natural and human features on Earth's surface. A map is a graphical representation of all or part of the Earth on a flat surface that presents information about the world, such as population patterns or rainfall. One of the earliest known maps dates back 4,000 years to Mesopotamia, and the art of cartography or mapmaking is believed to have originated from ancient Greece, where scholars like Eratosthenes and Ptolemy developed early maps and theories about the size and shape of Earth. Modern cartography has been enhanced by technologies like air photography, computing, and satellite imagery.

Cell theory
- In the 1600s, Robert Hooke observed "cells" under a microscope when examining cork and coined the term. Anton van Leeuwenhoek then described living cells from pond water in the 1670s.
- Scientists originally believed in the theory of spontaneous generation, that life could arise from non-living things like dust or decaying meat, until experiments by Francesco Redi and Louis Pasteur disproved this.
- Pasteur's experiments with swan neck flasks in the 1800s demonstrated that life only arises from other living cells, providing support for the cell theory that all living things are made of cells, cells come only from other cells, and cells perform functions necessary to sustain life
