Earth's Layers
The layer of Earth that is the least dense and the thinnest.
What is the crust?
Weathering and erosion of rocks creates this.
What are sediments?
This type of boundary causes earthquakes.
What are transform boundaries?
This law tells us the oldest rock is found at the bottom and the youngest rock is found at the top.
What is the Law of Superposition?
Deforestation has this effect on the earth.
What is an increase in erosion and loss of habitat?
The layer of Earth that is solid nickel and iron.
What is the inner core?
This rock is created by compaction and cementation of sediments.
What are sedimentary rocks?
Mountain building is a result of this type of boundary?

What is urbanization.
The sphere that consists of the crust and upper part of the mantle.
What is the Lithosphere?
This rock is created by heat and pressure.
What are metamorphic rocks?
This type of boundary occurs when two plates are moving away from each other.
What are divergent boundaries?
Supercontinent from hundreds of millions of years ago.
What is Pangea?
Overgrazing, harmful agriculture techniques, and deforestation can cause this.
What is desertification?
Uneven heating in the mantle causes this to happen.
What are convection currents?
This rock is created by magma/lava cooling.
What are igneous rocks?
This occurs as a result of Divergent boundaries.
What are mid-ocean ridges and rift valleys?
The Law of Superposition can only be used in this.
An undisturbed sedimentary rock
Native populations can experience this because of human activity.
