100
Natural features on the Earths surface such as mountain ranges, plateaus and canyons.
What is a landform?
100
Rainwater mixes with carbon dioxide and forms this type of liquid.
What is acid rain?
100
This process is the laying down of pieces of the Earth's surface.
What is deposition?
100
What is a weak spot in the Earth's crust where magma is forced upward and reaches the surface?
A volcano.
100
Describe what a fault is? Describe what an Earthquake is?
A fault is a break or crack in the Earth's crust that can have movement. An earthquake is the sudden movement that causes the Earth's crust to shake.
200
The outer surface of the Earth is a layer of rock called?
What is the crust
200
True or False- Sometimes animals and plants give off chemicals that can cause weathering.
True
200
True or False - Sometimes deposition happens slowly and other times it happens very fast.
True
200
True or False - Volcanoes and earthquakes cause large rapid changes to the Earth's surface?
True.
200
How can an earthquake change the Earth's surface? 1.- It can melt glaciers. 2.- It can cause fires. 3.- It can cause the climate to get hotter.
It can cause fires.
300
The process that breaks down rocks in the Earth's crust.
What is Weathering?
300
Water, Ice, Gravity, and Wind often work together to move weathered pieces of rock.
What is erosion?
300
Rivers deposit large amounts of material where they flow into the ocean. The deposited material forms a fan shaped area called a ?
What is a delta?
300
What is a dormant volcano? Name a dormant volcano that is located in a Pacific Northwest state.
A dormant volcano is a volcano that has erupted for a long time. Mount Rainer in the Cascade Mountains in Washington is considered dormant.
300
The energy of an earthquake moves in two forms what are these forms?
The energy moves in the form of waves or vibrations.
400
Only the size of the rock is changed. Large rocks are broken into smaller pieces of the same rock by these four things?
What is water, ice, living things, temperature? (W.I.L.T.)
400
Which of the following is an example of erosion? 1. -Faults moving below the surface of the Earth. 2.- Wind deposits weathered pieces of rock. 3.- Rocks are weathered by rain. 4.- Rainwater moves soil down a mountain.
Rainwater moves soil down a mountain.
400
Gravity pulls all objects from higher places to to lower places. The rapid down hill movement of a large amount ogf rock and soil is called?
A landslide.
400
What are two things that volcanic eruptions can produce?
Rock and ash.
400
In an Earthquake what is the focus point and what is the epicenter ?
The focus point is the place underground where the plates start to rub together and the earthquake begins. The point on the Earth's surface that is directly above the focus is the epicenter.
500
This is the process where rock is broken into smaller pieces, but the material that makes up the rock or soil also changes.
What is physical weathering?
500
How can a glacier erode a landform?
Ice melts into a thin layer of water at the bottom of a glacier. As the glacier glides along the Earth's surface on this water it wears away bits of rock and soil.
500
How is an Avalanche like a landslide, what can trigger an avalanche, and what is one way people can can try to prevent an avalanche?
An Avalanche is like a landslide because they both are rapid kinds of erosions. Avalanches can be triggered by strong winds, earthquakes, and explosions. One ay people might try to prevent avalanches is by clearing away snow before too much builds up.
500
How can ash affect surrounding areas?
It can cover surrounding areas killing trees and wildlife.
500
Describe one way that Earthquakes and Volcanoes are similar. Describe one difference between them.
Volcanoes and earthquakes are similar because both damage or change the earth rapidly. Volcanos and Earthquakes are different because volcanoes can change the climate and earthquakes can cause tsunamis.
