Mudslides are a rapid or slow change to the Earth's surface?
Rapid

Why do earthquakes occur along faults?
There are breaks in Earth's crust where the plates come together. Faults are where rocks move along the cracks. These are the areas where the plates push together or slide apart which creates an earthquake.
100
A volcano shaped like a cone with steep sides.
Cinder-cone volcano
100
It is a cup-like shape that forms around the vent of a volcano.
Crater
100
Areas where rocks slide past one another along cracks in Earth's plates.

Landslides are a slow or rapid change to the Earth's surface?
Rapid

What types of damage can an earthquake cause?
Tsunamis, landslides, mudslides, property damage, injuries, and death.
200
A volcano with sides that are wide and flat because it is formed by layer of lava that build up over time.
Shield volcano
200
Movements in Earth's crust caused by a sudden shift in Earth's plates.
Earthquake
200
When water runs on top of the land, causing streams and rivers to fill up and overflow.
Flood

What are the main differences between a mudslide and a landslide?
A landslide occurs when a large amount of loose rock and soil move rapidly down a slope and a mudslide occurs after a large amount of water has turned soil to mud. Only a mudslide involves water.
300
A fault where the plates push together.
Reverse fault
300
A volcano that is symmetrical and cone-shaped, made of layers of lava and ash.
Composite volcano
300
A place where magma partially melts through Earth's crust.
Hot spot
300
When a large amount of loose rock and soil move rapidly.
Landslide
400
What kind of damage can a mudslide and a landslide cause?
Both can carry debris with them and cause property damage.
400
A fault where rocks slide past each other in different directions.
Strike-slip fault
400
What is the difference between a dormant volcano and an active volcano?
Dormant volcanoes no longer erupt, while active volcanoes continue to erupt.
400
The land becomes so full of water that it becomes a river of mud.
Mudslide
400
Gigantic slabs of rock in Earth's crust that are always moving.

If you were going to build an emergency shelter to serve citizens during natural disasters, what issues would you consider before purchasing the land?
Location is important. Avoid: the coast (tsunamis), active fault lines (earthquakes), active volcanoes, the base of a hillside (mudslide or landslides).
500
A fault where the plates pull apart
Normal fault
500
Hot spots are a slow or rapid change to Earth's surface?
Slow
