The Four Main Spheres of Earth: Hydrosphere, Biosphere, Lithosphere and Atmosphere

This may increase photosynthetic production and eventually increase the amount of biomass, which, after a very long time, forms coal and oil deposits geosphere. The shape is often called a geoid Earth-like or an ellipsoid. For example, the image above distinguishes between lands covered with plants shown in shades of green and those that are not shown in brown. Biomes are then recognized by the types of dominant ecosystems— tropical rainforests, temperate forests, prairies, deserts, and Arctic Tundra. Another way of saying this is that the Earth's mass reached a pointwhere its internal gravitational forces overcame any other rigidforces that might have kept the Earth in a non-spherical shape. So hopefully you can see that everything we do on this planet affects something else even if we can't see it, or the effect isn't noticed for years. Basically lithosphere is nothing but a crustal system composed of various layers: Core, mantle and outer crust.

The first concept to learn in Earth Systems Science is the six main spheres of the planet. Students excitedly raise their hands, ready to contribute. To keep things simple in this module, there will be no distinction among the sub-spheres of any of the four major spheres. The gases like Nitrogen, Oxygen, Argon, Carbon dioxide and Water vapor etc. The lithosphere contains rocks and minerals which are helpful for building materials for various things.

Biosphere The biosphere contains all the planet's living things. Two-thirds of the remaining 3% is frozen in glaciers and polar ice caps. Also, it gets students thinking about and visualizing the Earth as a larger system itself. Extremely low temperatures like those found at the poles cause water to freeze into a solid such as a polar icecap, a glacier, or an iceberg. In addition, students will investigate how these systems interact in multiple ways to affect Earth's materials and processes by conducting research, constructing graphs, creating models, carrying out scientific investigations, and analyzing real-world applications.

The biosphere is composed of all living organisms: plants, animals and one-celled organisms alike. I explain: What's important to know about the four spheres on Earth is that they are interconnected. This layer is defined by the fact that all weather, such as precipitation, occurs here. Our knowledge of its inner workings and the systems that function within it continue to grow with each passing day. However, the composition of atmosphere and so also its structure is variable in time and space. Next comes the mesosphere, which extends to about 85 km above earth's surface. Throughout the unit, students will reflect upon this model to discuss how the systems interact with one another.

Hydrosphere: The hydrosphere contains all the waters on Earth. In tropical latitude its average height is 16 km. You are likely already familiar with some of these, like deserts, grasslands and rainforests. It is by far the heaviest of the spheres. Most of the water in the atmosphere is in gaseous form and as it rises higher into the atmosphere it condenses to form clouds which fall back on earth as precipitation. While asking questions and encouraging a high-level of student partcipation, we continue to take notes on the biosphere: Where can life be found on Earth? In any event, the effects of each cycle are felt in other cycles in other spheres. Atmosphere — This is the gaseous layer of air that encloses the Earth.

Earth's four major spheres are the lithosphere, biosphere, atmosphere, and hydrosphere. A simplified outline of hydrological cycle is given in Fig. We discuss that the atmosphere protects the biosphere as it keeps harmful ultraviolet rays out, but lets the sun's warming rays in solar heat. The higher the atmosphere, the thinner it becomes and this trait gradually moves towards space. If you were standing on the moon, looking at the Earth, it would be virtually impossible to see the bulge and the Earth would appear to be a perfect sphere.

A case could be made for each. The exact depth at which this happens depends on the chemical composition of the earth, and the heat and pressure acting upon the material. In fact, the boundaries between Earth's spheres are less concrete and really more theoretical. The Atmosphere The final sphere is one you've probably already heard of. The ecosystems again composed of populations and population composed of individuals.

Beneath that layer lies a very thin, solid crust of oxygen and silicon. The entire ecological communities within the physical surrounding of the earth are within the umbrella of living things biosphere. Cenozoic Present Era Ice Age; mammoths; gradual development of mammals, birds and other animals recognizable today; humans; flowering plants, forests, grasslands. Most of this life exists no deeper than about 10 feet into the ground or about 600 feet above it. The four spheres show how the four main components of Planet Earth form a complete system. The remainder is fresh water, two-thirds of which is frozen within the earth's polar regions and mountain snowpacks. Each desk group has about six kids, so I simply divide this larger group in half or thirds.

Monitoring Student Understanding Once students begin working, I conference with every group. The four parts are called the geosphere, hydrosphere, atmosphere, and biosphere. The next layer of the atmosphere is the stratosphere. The Cryosphere is sort of like a sub sphere of the hydrosphere. The atmosphere itself rises to about 10,000 km in height and is divided into four zones.

In fact, the Earth is not a perfect sphere. Students then explore each of the earth's systems through a teacher presentation and rich class discussions. Without the magneticfield, the atmosphere would go away. Winds and clouds in the atmosphere interact with the landforms to determine patterns of weather. These four spheres all interact with one another, as evidenced by the precipitation cycle and the effects of pollution on the world.
