Tsunami

100

How do earthquakes generate Tsunamis?

Most tsunami are caused by large earthquakes on the sea floor when slabs of rock move past each other suddenly, causing the overlying water to move.

200

How fast can Tsunamis travel?

over 900km/hour

300

What issues (other than building destruction) can Tsunami's cause? List 3

List 3

- Water contamination

- destroy crops/food

- create landslides, mudslides

Any other reasonable answer

400

Hoe big can Tsunami's get?

Up to 30m above sea level 

500

Do Tsunamis waves break? Explain why/why not

Tsunami waves are unlike typical ocean waves generated by wind and storms, and most tsunamis do not "break" like the curling, wind-generated waves popular with surfers.

Plates

100

What are the 2 types of plates?

Continental and Oceanic

200

At which plate boundary is new rock likely formed?

Divergent plate boundaries

300

A new mountain range has been formed. What is the most likely plate boundatry?

Continental Continental Convergent

Earthquake

100

what is an earthquake?

Earthquake is a term used to describe both sudden slip on a fault, and the resulting ground shaking and radiated seismic energy caused by the slip, or by volcanic or magmatic activity, or other sudden stress changes in the earth.

200

What 2 plate boundaries are more likely to experience earthquakes

Convergent and transform

300

Why do earthquakes occur suddenly?

Plates get stuck at their edges due to friction. When the friction breaks, there is a sudden energy release (earthquake!)

400

How do earthquakes cause damage? List 4

- Building destruction

- unstable ground/sinkholes

- destroy roads

- destroy 

Any other reasonable answers

500

What are the differences between P waves and S waves? List 2 things

P waves come first

P waves push and pull, S waves move side to side

Volcano

100

Where are most volcanos found?

Ring of fire!

200

Where are the two main areas volcanoes are formed (things about plates and boundaries)

Convergent plate boundaries

Hot spots

300

How does a convergent boundary lead to a volcanic eruption? List in 3 steps

- Plates hit each other and one sinks

- the sunken plate melts due to heat and pressure

- the melted plate material rises upwards due to pressure and can explode

400

How do hot spot volcanoes form island arcs? Give 4 dot points

hot spot volcanoes occur in the middle of plates not at boundaries (1)

The magma burts through the surface because it is especially hot (1)

The magma cools and forms an island (1)

Then the plate continues to move and drags the island away, which then leaves the hot spot free to make another island
