Earth's Sphere's, Interior & Continental Drift - Nazar
1.
2. Earth Interior is a part of
the earth beneath the crust
Lithosphere is the outer part of the earth
Hydrosphere is the waters of the earth’s surface
Atmosphere is mass of air surrounding the earth
3. Layers
Oceanic Crust is land underneath the ocean
Continental Crust is rocky outer layer of Earth
Mantle is thick layer and is made up of melted rock
Outer Core is 2,250 km thick and is completely liquid
Inner Core is solid and is made up of nickel and iron
4. Summary
There are three major types of the earth interior types:
atmosphere, hydrosphere, lithosphere.
Earth is divided in different parts called layers. Outer
layer of the earth has continental and oceanic layers.
Underneath these crusts there’s a mantle, liquid
magma. Underneath the mantle there’s a outer core,
total liquid. Mantle and outer core are both liquid but
they never mix. And last deepest layer is inner core and
is solid made of metal.
5. Questions
What are the layers of earth interior?
Where are the layers located?
6. Continental Drift
Continental Drift is a theory that all the
continents had formed one landmass before
breaking apart and drifting to their present
locations.
7. This landmass was called Pangea. The theory was
brought by Alfred Wegener in 1915.
11. Summary
Continental Drift is a theory that all the continents were
together. This theory was brought by Alfred Wegener in 1915.
There are three types of evidence that support Alfred’s
theory.
#1 Puzzle
#2 Fossils
#3 Ladnforms
