Give three out of the five "W's" about Haiti's Earthquake.
Who:
The people of Haiti, especially those living in and around Port-au-Prince. Over 3 million people were affected.
What:
A powerful earthquake measuring 7.0 magnitude that caused massive destruction of homes, schools, hospitals, and government buildings.
When:
January 12, 2010, at 4:53 p.m. local time.
Where:
Near Port-au-Prince, Haiti’s capital city, with the epicenter about 15 miles southwest of the city.
Why:
The earthquake happened because of movement along the Enriquillo–Plantain Garden fault, where two tectonic plates (the Caribbean Plate and North American Plate) slide past each other.

What is the difference between magma and lava
Magma is molten rock BENEATH the Earth's surface.
Lava is molten rock ON the earth's surfact. (Magma turns into lava)

Name the three types of volcanoes and define each
Extinct - a volcano that erupted a long time ago and will not erupt again.
Dormant- a volcano that has not erupted in a long time, and there is a chance it will.
Active- a volcano that is erupting, or has recently erupted and will erupt again.

Give 3 out of the 5 "W's" on Mt. St. Helen
Who:
People living in and around Washington State,What:
A major volcanic eruption occurred, causing an explosion, landslides, ash fall, and destruction of forests and buildings.When:
May 18, 1980 (the most famous eruption).Where:
Mount St. Helens, in Washington State, USA, part of the Cascade Range.Why:
Pressure built up when magma rose beneath the volcano, causing the mountain to become unstable and erupt after an earthquake triggered a landslide.

Before - have an emergency kit, have a family meeting place, and conduct a practice drill.
During - stay calm, move away from windows, drop/cover/hold
After- be alert and cautious, expect aftershocks, check yourself for injuries, and check for information.
