There are several conflicting definitions of “geosphere.” However, one generally accepted usage is The physical environment within which human beings exist. Geology is the collective name for the lithosphere, the hydrosphere, the cryosphere, and the atmosphere. Different collectives of the geosphere can exchange different mass and energy fluxes (the measurable amount of change). When these changes occur in the earth’s different layers or spheres, it affects the balance of that sphere and the resulting effect is felt throughout the geosphere. If you are looking for a good example, then the Earth’s soil can be used to explain the concept of a biosphere.
Modern texts and Earth system science sometimes list geosphere along with the atmosphere, hydrosphere, and biosphere to describe Earth’s systems. Geosphere means the solid parts of the Earth. Instead of saying the lithosphere is the strongest part of the Earth’s structure, we can say it’s the part that contains most of the planet’s mass. The lithosphere, however, refers only to the uppermost layers of the solid Earth. These are the oceanic and continental crustal rocks and the uppermost mantle.
Types of Geosphere
The Earth has a geosphere that is made up of three layers: The lithosphere, the hydrosphere, and the atmosphere. Together, these layers form a system that regulates the conditions on our planet and provides a livable environment for us to inhabit. However, human activity is re-shaping this system and it’s reshaping our climate as well.
- The lithosphere (rock layer) is the “outer shell” of Earth. It is made up of the crust, the upper mantle, and the lower mantle (these areas have the highest temperature, pressure, and resilience).
- The Hydrosphere – The hydrosphere is the water that surrounds our planet. It mostly consists of oceans with smaller amounts in the atmosphere, ice caps, and groundwater. The most significant change in this sphere is the rapid melting of ice caps and glaciers due to global warming.
- The Atmosphere – The earth’s atmosphere is made up of layers. The lower levels are the troposphere, stratosphere, mesophere, and thermosphere. They are all very close to the Earth’s surface. The hydrosphere is anything that has water in it, including oceans, rivers, lakes, glaciers, ice caps and even clouds. There are many ways in which the hydrosphere is changing on Earth.
Geosphere Changes Due to Global Warming
A warming planet is having drastic effects on Earth’s gravitational pull, which has altered the global balance of water on the planet. A study conducted by scientists at the Scripps Institute of Oceanography found that melting glaciers have decreased water weight pressure on the Earth’s surface, which results in a stretching of Earth’s crust down into thicker layers of rock below. This stretches tectonic plates and increases volcanic eruptions. The study also found that the weight of the ocean has increased on the ocean floor, which is affecting the water pressure on Earth’s surface. This causes a lowering of sea levels, which is currently happening in the coastal regions of the world.
How does the geosphere interact in the earth system?
The Earth appears to be incredibly stable, but it is, in fact, an extremely active participant in the larger systems of which it is a part. By understanding how the various parts of our planet interact, we can more fully understand what is happening to us, our world and our future. Minerals are important. They determine the nature of the soil and the plant life that grows in the soil.
One example is: Manganese is important because it acts as an enzyme activator. Carbon is essential for life. It’s the basic building block of all organic matter in the earth’s crust, which are carried to the ocean by winds and rivers and eventually become part of the ocean floor. As oceans become depleted of minerals and other substances they are forced to erupt in massive waves of water, which migrate across the surface of the earth as a series of destructive tectonic plates. The volcanoes that can be detected by our satellite-based system are the ones with the largest emissions of carbon dioxide. These volcanic systems are among the most dangerous because they can vent large quantities of carbon dioxide into the atmosphere. Carbon is one of the elements that link the geosphere (where it is found only in the earth), the atmosphere (where it is present in trace amounts), the hydrosphere (where it is the most abundant element), and the biosphere (where it is essential for all life as
The inner core of the earth is made of solid iron. Without the moon, our planet would be an uninhabitable wasteland. The moon maintains a constant gravitational pull on Earth, which in turn produces a magnetic field that protects us from solar winds and cosmic radiation. Without the moon, life on Earth would be very difficult if not impossible. A hot new layer, geothermal technology could eventually allow us to harness greater amounts of heat energy from within the crust and convert it to electricity at the surface.
