Social Studies Flashcards About Earthquakes And Hurricanes

What is an earthquake?

An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.

What causes earthquakes?

Earthquakes are caused by the movement of tectonic plates, which can lead to stress accumulation and eventual release.

What are tectonic plates?

Tectonic plates are large sections of the Earth's crust that move and interact with each other at their boundaries.

What is the focus of an earthquake?

The focus is the point within the Earth where an earthquake originates, usually located along a fault line.

What is a hurricane?

A hurricane is a type of tropical cyclone characterized by strong winds and heavy rain, forming over warm ocean waters.

What is the Saffir-Simpson Hurricane Wind Scale?

The Saffir-Simpson Hurricane Wind Scale categorizes hurricanes into five levels based on their sustained wind speeds and potential damage.

What are the conditions necessary for hurricane formation?

Hurricanes require warm ocean water (at least 26.5°C), moist air, and low vertical wind shear to form.

What is the eye of a hurricane?

The eye of a hurricane is a calm, clear area at the center of the storm, surrounded by the eyewall, where the most severe weather occurs.

How do hurricanes impact coastal regions?

Hurricanes can cause severe flooding, storm surges, and wind damage in coastal regions, leading to significant destruction and loss
