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 a common geological event at transform boundaries.

What is an earthquake?

100

The placing of materials in a new place.

What is deposition?

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

A landform that can form at convergent boundaries.

What is a volcano?

200
The destructive process which moves materials away from their place (due to gravity, water and wind).
What is erosion?
200

Earth's outermost and thinnest layer.

What is the crust?

300

Developed the Continental Drift Theory

Who is Alfred Wegner?

300

Plant roots break apart rocks.

What is mechanical weathering?

300

This is what we call the zone where one plate sinks other another plate.

What is a subduction zone?

300

This is how farmers can prevent wind erosion of topsoil.

What is surrounding fields with natural barriers (such as trees)?

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

Limestone breaking down due to acid rain.

What is chemical weathering?

400

The place where two plates come together.

What is a convergent boundary?

400

These kind of forces build new features on the Earth's surface (such as mountains)?

What is convergent boundaries?

400

Earth's magnetic field results from movements in this.

What is the outer core?

500

Discovered that the sea-floor is spreading.

Who is Harry Hess?

500
BOTH mechanical and chemical weathering accomplish this.
What is the breaking down of rock into smaller pieces called sediment?
500

This is the type of plate boundary where new crust is formed.

What is a divergent boundary?

500

This is what forms landforms such as deltas and sand dunes.

What is deposition?

500

Most geologists think that the movement of Earth's plates is caused by this.

What is the convection currents in the mantle?
