Earth's Layers (cont.)
100
The correct order of Earth's layers, starting with the surface?
What is the crust, mantle, outer core, and inner core?
100
The changing of materials by chemical processes.
What is chemical weathering?
100
This is the force people feel when two plates jerk into a new position?
What is an earthquake?
100
Earth's inner core is made of this.
What is a dense ball of solid metal?
200
The top part of the mantle and the crust above it.
What is the (Earth's) lithosphere?
200
The breaking down of rock into smaller pieces by forces.
What is mechanical weathering?
200

Name the layers Mantle is divided into

lithosphere, Asthenosphere and lower mantle

200
Earth's outermost and thinnest layer.
What is the crust?
300

which crust is heavier oceanic or Continental and why?

Oceanic crust is heavier because it is made up of basalt while Continental crust is made of basalt which is lower in density.

300
Give an example of how mechanical weathering may occur.
What is the force of gravity, ice or plant roots?
300
This is where most earthquakes happen.
What is at plate boundaries?
300
This famous tourist attraction was formed when a river continued to erode rock over a long period of time.
What is the Grand Canyon?
400
This soil layer has the greatest amount of decayed material.
What is the top layer?
400
Give an example of how chemical weathering may occur?
What is chemicals in rain dissolving rocks over time?
400

The place where two plates come together.

What is a convergent boundary?

400
Earth's magnetic field results from movements in this.
What is the outer core?
500
This is how scientists learn about the mantle and core of the Earth.
What is studying the material that pushes through cracks in the crust?
500
BOTH mechanical and chemical weathering accomplish this.
What is the breaking down of rock into smaller pieces called sediment?
500
This is what a crack in the Earth's crust is called.
What is a fault?
500
Most geologists think that the movement of Earth's plates is caused by this.
What is the convection currents in the mantle?
