AN ACTIVE

PLANET

Earth is a busy planet. The earth and sun

provide all of the ingredients for life to thrive.

But the earth is not always a gentle and forgiving

home. Natural forces on earth make it an

unpredictable place to live.

Weather is a natural force that affects plants

and animals. Weather cannot be controlled, but it

can be forecasted. Even deadly weather events

such as hurricanes, tornadoes, and floods can

often be predicted. Advance warning gives

people a chance to prepare or escape. However,

some forces of nature are much harder to predict

and that makes them especially dangerous.
