The Interiors of Earth comprises of Soil, Earth & Crust.
SUMMARY OF INTERIORS OF EARTH
Mantle Middle & thickest layer Composed of hot, dense rocks. Rocks flows like asphalt 2/3rd of the earth’s mass 1800 miles thick
Crust Outer layerConsist of heavy metals1/250 of earth mass25 miles thick
Core Very hot1/3 of the earth’s massOuter Core: Iron & Nickel in
liquid state; 1400 miles thickInner Core: Iron & Nickel in
solid state; 800 miles thick
What is Soil ??The upper layer of earth in which plants grow, a
black or dark brown material is known as Soil.
Formation of Soil
CrustNow , Let’s learn about the Earth’s crust.The crust of the Earth is composed of a great
variety of igneous, metamorphic, and sedimentary rocks. This drawing shows the Crust, Upper Mantle, Mantle, Outer Core, Inner Core.
What is Crust ??• opppppThe Earth's crust is an extremely
thin layer of rock, like the skin of an apple in relative terms. It amounts to less than half of 1 percent of the planet.
Formation of Crust
Crust is formed along boundaries between tectonic plates which are moving apart. Most crust creation takes place on the ocean floor at the mid-ocean ridges. As the plates move apart, solidifying magma rises, filling fractures and openings created by the divergence. Some lava also spills out into the seawater, creating pillow basalts on the seafloor. The entirety of the oceanic crust has, and is, being created in this manner.
