Study Notes
Earthquakes and Polar Bears
Earthquakes
- An earthquake is a sudden, rapid shaking of the Earth's surface caused by the release of energy stored in the Earth's crust.
- Approximately 50,000 detectable earthquakes occur in the world each year.
- However, only about 100 of these earthquakes cause damage.
Importance of Earthquake Safety
- It is crucial to be aware of safety measures during an earthquake to minimize injury and damage.
- Earthquakes can occur anywhere, making it essential to have a plan in place for emergency situations.
Polar Bears
- The primary reason for the decline in polar bear populations is the decline of their primary habitat, sea ice.
- Polar bears are closely tied to sea ice, using it as a platform to hunt and breed.
