Layers
This layer is is made of solid, rigid basalt.
What is Oceanic Crust.
This type of boundary occurs when two plates move apart.
What is a divergent boundary.
This sphere contains all of the gases on Earth.
What is the atmosphere.
This layer of Earth "floats" on the Asthenosphere.
What is the crust or lithosphere.
This is how far, on average, that each plate moves per year.
What is two inches.
This layer is also known as the Asthenosphere.
What is the mantle.
This type of boundary creates subduction zones.
What is a convergent boundary.
This sphere contains all of the water in oceans, rivers, lakes, and glaciers.
What is the hydrosphere.
These type of plate collides with a continental plate in the crust to form a mountain.
What is a continental plate.
This is the thickest layer of Earth.
What is the mantle.
This layer is the hottest layer.
What is the inner core.
This type of boundary causes mountains to form.
What is a convergent boundary.
This sphere contains soils, rocks and nonliving material.
What is the geosphere.
This type of plate in the crust is less dense and older.
What is a Continental plate
This is where there is 75% of volcanoes and 90% of all earthquakes occur.
What is the ring of fire
This layer is made up of liquid iron and nickel.
What is the outer core.
This type of boundary is occurring at the mid-Atlantic ridge.
What is a divergent boundary.
This sphere contains all of the living organisms.
What is the biosphere.
These type of plate in the crust is newer.
What is oceanic plates
This is the name of the super continent where all of the land was connected.
What is Pangea.
This layer is made up of the crust and upper part of the mantle.
What is the lithosphere.
This type of plate boundary creates strong earthquakes but doesn't create or destroy plates.
What is a transform boundary.
Plants reduce soil erosion by protecting land from weather thru and interaction between the biosphere and this sphere.
What is the geosphere.
This type of plate in the crust is made of granite.
What are continental plates.
This gentlemen was responsible for the continental drift theory.
