crust?

crust – the outermost solid layer of Earth, the part we live on

1
What is the...

mantle?

mantle – the layer of Earth just below the crust, which contains most of Earth's mass

2
What is the...

core?

core – the innermost layer of Earth

3
What is the...

lithosphere?

lithosphere – the Earth's crust and the solid, upper part of the mantle

4
What is the...

continental drift?

continental drift – the theory that the continents drifted apart in the past and continue to do so

5
What is the...

plate techtonics?

plate tectonics – the theory that Earth's lithosphere is broken into about 20 moving plates

6
What is the...

plate boundaries?

plate boundaries – areas where two plates meet

7
What is the...

fault?

fault – a break in Earth's crust

8
What is the...

focus?

focus – the underground location where the earthquake occurs

9
What is the...

epicenter?

epicenter – the point on the Earth's surface directly above the focus

10
What is the...

Richter Scale?

Richter Scale – is a measure of an earthquake's strength, goes from 1-10, each increase of 1 on the scale is an increase about 31 times of energy released.

mechanical weathering?

mechanical weathering – breaking down of rock, by wind, water, and ice

22
What is the...

chemical weathering?

chemical weathering – a change in minerals as they react with substances in the environment, such as water or oxygen

23
What is the...

erosion?

erosion – the process by which soil and sediments are transferred from one location to another, usually by wind, water, ice and gravity

24
What is the...
