what should you do if there is a flood warning in your area?
move to higher ground right away
200
How are the causes of landslides and floods similar?
both can be caused by storms
200
How do the plates move in a strike-slip fault?
They slide past each other.

What is a sign of a landslide?
Small slides/new cracks tilting trees/telephone poles unusual sounds
300
This is an effect of landslides
carry trees,homes,cars property damage millions of kg soil and rocks
300
What usually causes tsunamis?
Earthquakes
300
What does the shape of a volcano depend on?
The shape of a volcano depends on the kind of lava that erupts from it.

Why do earthquakes happen more in California than in other places in the United States?
A major fault line run through California called the San Andreas Fault.

Keeping heavy items low to the ground or bolted down is a safety tip for what disaster?
What is Earthquake
400
How is a mudslide different from a landslide?
a mudslide is the movement of wet soil and rocks down a slope, while a landslide is the movement of dry soil and rocks down a slope.
400
Which fault pushes plates together?
Reverse fault
400
How do cinder-cone, shield, and composite volcanoes differ from one another?
Cinder-cone volcanoes are cone-shaped and have steep sides. Shield volcanoes have wide, flat sides formed by layers of lava that have built up over time. Composite volcanoes usually have symmetric sides made up of layers of lava and ash that eventually build up to form a cone shape.

Goggles and breathing masks are needed for what disaster?
What is volcano
500
what is the main cause of landslides?
gravity
500
How do slow and quick movements along a fault differ in the way they affect us?
Slow movement is called "creep" and does not usually cause large earthquakes. Sudden movement shakes the crust and can cause large earthquakes.
500
Which type of volcano forms through a period of quiet eruption and explosive eruptions.
Composite Volcano
500
How did the Hawaiian Islands form?
A plate moves over a Hot Spot. Lava builds up around a vent. When the lava build up reaches the surface an island is formed. As the plate continues to move slowly multiple islands form in an island chain, similar to the Hawaiian Islands.

How do you protect yourself from a landslide when caught in debris?
What is tight ball formation and protect head
