True or false: Tsunamis are not dangerous once they hit land.

FALSETRUE

What natural disaster occurs when massive waves occur because of underwater earthquakes?

TsunamisFloodsTornadosBlizzard

Tsunamis

Tsunamis are massive waves caused by underwater earthquakes.

What commonly causes tsunamis to form?

EarthquakesWarm temperatures that occur during eclipsesCold weather and high windsSeasonal animal migrations

Earthquakes

How tall can tsunami waves get when they reach the shore?

Over 1000 feetOver 100 feetOver 50 feetOver 10,000 feet

Over 100 feet

How do scientists think ants can tell when an earthquake is coming?

They think ants smell changes in the earth's core.They think ants can sense the ground vibrating through their feet.They think ants can taste differences in their food.They know ants cause the earthquakes

They think ants can sense the ground vibrating through their feet.
