Earth's Crust
Rainwater mixes with carbon dioxide and forms this type of liquid.
What is acid rain?
Natural features on the Earths surface such as mountain ranges, plateaus and canyons.
What is a landform?
This process is the laying down of pieces of the Earth's surface.
What is deposition?
What is a weak spot in the Earth's crust where magma is forced upward and reaches the surface?
A volcano.
Describe what a fault is?
A fault is a break or crack in the Earth's crust that can have movement.
The outer surface of the Earth is a layer of rock called?
What is the crust
True or False - Sometimes deposition happens slowly and other times it happens very fast.
True
True or False - Volcanoes and earthquakes cause large rapid changes to the Earth's surface?
True.
Earthquakes are measured on this device.
What is a seismograph (or seismogram)
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?
What is a dormant volcano?
A dormant volcano is a volcano that has erupted for a long time.
The energy of an earthquake moves in two forms what are these forms?
The energy moves in the form of S waves or P waves.
Which of the following is an example of erosion?
A. -Faults moving below the surface of the Earth.
B.- Wind deposits weathered pieces of rock.
C.- Rocks are weathered by rain.
D.- Rainwater moves soil down a mountain.
Rainwater moves soil down a mountain.
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.
What are two things that volcanic eruptions can produce?
Rock and ash.
In an Earthquake what is the epicenter?
The point on the Earth's surface that is directly above the focus is the epicenter.
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.
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.
How can ash affect surrounding areas?
It can cover surrounding areas killing trees and wildlife.
Describe one way that Earthquakes and Volcanoes are similar.
Volcanoes and earthquakes are similar because both damage or change the earth rapidly. Or they are both caused by sudden changes to plates along fault lines.
