What happens when lava cools and hardens?
It becomes an igneous rock and forms a new crust. This can also form mountains.

What can happen as a result of an earthquake?
buildings fall, cracks in the earth, landslides.

What is weathering?
action that breaks rocks into smaller pieces.
200
What is the thinnest layer of the Earth?
the crust
200
What forms when water slows enough to fill an area?
Lake

What is magma called when it erupts from a volcano?
Lava

What is a landslide?
A landslide are downhill movements of rock and earth.

How can a plant cause weathering?
a plant can grow in the cracks of rocks and split them apart.

What are the four layers of the Earth?
crust, mantle, outer core, inner core
300
What is a coast?
a coast is land next to the ocean, which helps to shape the coastline.
300
Where is magma formed?
In Earth's mantle, gathers underground in magma chambers.

What level of the Earth does an earthquake happen on?
crust

How can water break apart a rock?
get into the crack and expand in cold weather

What food can be used to describe the different layers of the Earth. Describe each layer on the food.
Ex: apple, pizza, peach

What is a plateau?
a plain that is higher than the land around it.
400
What does magma move through in a volcano?
central vent
400
How can an earthquake change the Earth's surface?
cause cracks in the crust
400
What causes a rockslide?
gravity
500
What is it like in the center of the inner core? What does in consist of?
Very hot, made of metal, packed together so tightly it remains mostly solid.

What happens as rivers move through rock?
Rivers act like saws. Pebbles and sand in moving water cut slowly through rock. Flooding rivers deposit pebbles, sand, and silt on the banks. Rivers will form valleys.

What are the four steps of a volcano erupting?
1. Magma forms in the mantle, and gathers underground in magma chambers.
2. Magma pushes upward through cracks and weak spots in Earth's crust.
3. When magma erupts from the volcano, it is called lava.
4. The lava cools and hardens and forms rocks.
500
How does an earthquake happen?
when the crust moves along eachother at faults or cracks in the Earth's crust

How does erosion and weathering constantly change Earth's surface? Give one way they are alike and one way they are different.
weathering breaks rocks into smaller pieces. the formations of these rocks change shape over long periods of time. Erosion is the movement of weathered material. Both change landforms over a long period of time. Erosion uses weathered particles to change the shape of landforms while weathering produces the particles used in erosion.
