Subsystem of the earth tour
Storyboard Text
- Hi i am your tour guide and im gonna take you to a place called subsystem of the earth, are you ready? Great! Let's go!
- We can take care of our Lithosphere by planting the same crop over and over strips vital nutrients in the lithosphere. Overgrazing an process that removes excessive amounts of plants by using animals to strip and erode the topsoil so no plants should be able to grow.
- Reduce Chemical Use. Use fewer chemicals around your home and yard, and make sure to dispose of them properly - don't dump them on the ground!
- So.. what are the subsystem of the earth? Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air). Each of these four spheres can be further divided into sub-spheres.
- The biosphere is as important as life itself because it is all of life. Without the biosphere, Earth would be a lifeless planet such as Mars or Venus. As natural resources are rapidly depleting human instability increases. We must devise ways for the sustainable use of our biosphere
- The Lithosphere contains all of the cold, hard solid land of the planet's crust (surface), the semi-solid land underneath the crust, and the liquid land near the center of the planet. The surface of the lithosphere is very uneven. There are high mountain ranges like the Rockies and Andes, huge plains or flat areas like those in Texas, Iowa, and Brazil and deep valleys along the ocean floor
- We can take public transportation, ride a bike, or walk whenever possible. This will reduce the amount of pollutants emitted into the air. Use cleaner fuels and more fuel-efficient products. Encourage your parents and other grown-ups to use cleaner fuels in their car.
- Next is the The Hydrosphere -- contains all the solid, liquid, and gaseous water of the planet.A small portion of the water in the hydrosphere is fresh (non-salty). This water flows as precipitation from the atmosphere down to Earth's surface, as rivers and streams along Earth's surface, and as groundwater beneath Earth's surface. Most of Earth's fresh water, however, is frozen.
- This is the end of our tour i hope you learned about the subsystem of the earth.Bye
- the Biosphere --contains all the planet's living things. This sphere includes all of the microorganisms, plants, and animals of Earth. Within the biosphere, living things form ecological communities based on the physical surroundings of an area. These communities are referred to as biomes. Use natural resources such as timber from trees and clay from the ground in construction. Many people around the world rely on plants and animals for fuel for heating and cooking. .
- After that is the Atmosphere--contains all the air in Earth's system. It extends from less than 1 m below the planet's surface to more than 10,000 km above the planet's surface. The upper portion of the atmosphere protects the organisms of the biosphere from the sun's ultraviolet radiation. It also absorbs and emits heat. When air temperature in the lower portion of this sphere changes, weather occurs.
