THE GEOSPHERE

THE WORD GEOSPHERE COMES FROM THE GREEK WORDS "GEO" MEANING EARTH, AND "sPHAIRA" MEANING BALL OR SPHERE.

WHAT IS GEOSPHERE?

the geosphere is all about the solid matter that makes up our planet, extending from the earth's surface down to its core. everything that is solid and situated on our earth's surface is part of the earth's geosphere. (example : mountain, volcanoes, and hills)

layers of the earth

the geosphere also consists of the layers of the earth. crust - outside layer of the earth. mantle - lies below the crust. core - consists of inner and outer core. the cores are the center of the earth.

the rock cycle

beside these parts, geosphere is also about processes. The processes of the rock cycle such as metamorphism, melting and solidification, weathering, erosion, deposition, and burial are responsible for the constant recycling of rocks on Earth between sedimentary, igneous, and metamorphic states.

kinds of rocks

1.Sedimentary rocks are formed via weathering and transport of existing rocks, and then deposition, cementation, and compaction into sedimentary rock.

kinds of rocks

2. Igneous rocks are formed by the cooling and crystallization of molten rock.3. Metamorphic rocks are formed when heat or pressure is applied to other rocks.

The primary agent driving these processes is the movement of Earth’s tectonic plates, which creates mountains, volcanoes, and ocean basins.

How does the geosphere interact with other spheres?

The atmosphere provides the geosphere with heat and energy needed for rock breakdown and erosion. The geosphere, in turn, reflects the sun's energy back into the atmosphere. The biosphere receives gases, heat, and sunlight (energy) from the atmosphere.
