What is Gravity? 

A pulling force that acts on all objects.

What is a flood? 

Large amount of water overflowing the sides of a river or a drain.

What is an earthquake? 

A sudden movement in the crust

What is a volacano? 

A mountain built up around an
opening in the crust.

100

A giant ocean wave. 

I am a Tsunami

What is a landslide? 

When a large amount of loose
rock and soil moves rapidly. 

200

What is a mudslide? 

water-soaked land that
slides down a hill.

The ______ is Earth’s outermost layer. 

The CRUST is Earth’s outermost layer

At the center of a volcano is
an opening called a _____.

Vent

My name is Mauna Loa, I am a shield _____, I am the world's largest ____. 


Volcano!

How can an earthquake cause  landslide to happen? 

A landslide is caused by things that quickly shift the
land, such as an earthquake.

300

Large amount of water and its fast speed
can cause what kind of damage? 


• floods can damage cars and buildings
• floods can wash away bridges
• floods can carry away soil from farmland
• floods can carry soil and mud and drop them
onto homes, streets, and cars.

The crust is broken into huge pieces, or _____.
The ______ fit together like puzzle pieces. Unlike
puzzle pieces, the ______ can move.

The crust is broken into huge pieces, or PLATES.
The PLATES fit together like puzzle pieces. Unlike
puzzle pieces, the PLATES can move.

As magma rises up through
a vent, it reaches the surface.
When magma reaches the
surface, it becomes_______.

LAVA

I am caused by:
• underwater landslides
• underwater erupting volcanoes
• most often, underwater earthquakes.

Tsunamis

In California, landslides
often occur along the ______ and in
the ______ 

In California, landslides often occur along the COAST and in the MOUNTAIN

Should you cross streams and rivers if they look flooded? 

NO

400

What is a crack in the crust? 

 A fault 

400

What are some kinds of volcanoes?

  1. Shield Volcano

  2. Composite Volcano

  3. Cinder-Cone Volcano

I caused a sudden shift in the Earth's crust in 1989 during the World Series baseball game 


 

Earthquake

500

How can landslides can even occur due to
the freezing and thawing of rocks?

When water freezes in the cracks of
rocks, it can split them apart. The
pieces of rock can become loose
and quickly slide down a slope

500

What is the first rule of flood safety? 

Move to higher ground and stay away from flood waters. 

500

What are the 3 different types of faults and what do they do? 

Reverse Fault
The plates push into each
other. The part of the crust
above the fault surface (in this
case, the right side) rises up.


Strike-Slip Fault

The plates slide past each other along the fault.


Normal Fault

The plates pull apart. The part
of the crust above the fault
surface (in this case, the right
side) moves down



500

What are craters? 

Pressure builds up from
gases in the magma. The gases
finally explode out of the magma.
Lava bursts into the air. It falls in
pieces around the vent. A cup-like
shape forms around the vent of a
volcano.

In in the early 1990s I cause BILLIONs of dollars of damage.
