True or False: Earth's surface is constantly changing.
True! Because of erosion Earth's surface is changing every day!
100
This thing is caused by two tectonic plates shifting and rubbing at their fault line. This very quickly changes Earth's surface and can cause a great amount of damage.
What is an earthquake?
200
The middle layer of the Earth is called the ____________.
Mantle
200
Define the term landform.
A shape on Earth's surface.

What are tectonic plates?
The Earth's crust is separated into large sections like pieces of a puzzle. These pieces are called tectonic plates and are constantly moving, although very slowly.
200
Where do earthquakes commonly occur?
Earthquakes occur where two tectonic plates meet (at the fault line).
300
What is the difference between the inner core and outer core?
The inner core is solid metal and the outer core is molten (or melted) metal.
300
What is the difference between a mountain and a volcano?
Mountains are usually created when tectonic plates shift together and the crust is moved upward. In contrast, volcanoes grow larger by erupting over and over again. The lava cools after eruption and the volcano becomes larger.

What is a fault line?
A fault line is the place where two tectonic plates meet.
300
Earthquakes are measured using this scale.
What is the Richter Scale?
400
What is the difference between the mantle and the outer core, if they are both liquids?
The mantle is molten rock and the outer core is molten metal.

Why is a glacier not technically a landform?
Glaciers are actually considered bodies of water. They are frozen and massive so they appear to be a landform, but are not because they are made out of water.

What are the four ways by which erosion occurs?
Wind, water, sand, plants
400
What is the difference between lava and magma?
Lava is the molten rock that spews out of an erupting volcano and cools on its surface. Magma is the molten rock and gas mixture inside of the volcano as well as in the mantle of the Earth.

Why can we use an apple to model the layers of the Earth?
The apple is structured just like the Earth. The outside of each is covered by a thin layer compared to the size (the skin of the apple and the crust of the Earth). Inside is the next layer, the mantle of Earth or the juicy inside of the apple. Finally, both the apple and the Earth have an inner core.

Describe two ways by which landforms are created.
Landforms are created by:
-movement of glaciers
-erosion
-movement of tectonic plates
500
Describe two ways by which Earth's surface changes.
Ice melting and freezing, cracking rocks.
Water moving sand, pieces of rock, etc. to new locations.
Earthquakes moving rock.
Glaciers carving out land.
Wind moving sand or small pieces of rock.
Sand scraping away at pieces of rock.
Tectonic plates moving.
Volcanoes erupting and growing larger.

What is the effect of earthquakes and volcanoes on Earth's surface?
Both earthquakes and volcanoes very quickly change Earth's surface when they occur. They can cause a great amount of damage and greatly change the crust of the Earth where they occur.
