| Swamps | found in warm and wet environments |
| Mountain tops | have cool temps and low humidity |
| Base of mountain | usually has the same climate as the surrounding area |
| Factors affecting climate | average temperatures and precipitation are the key parts |
| latitude, elevation and nearness to large bodies of water | affect climate |
| latitude | the distance north or south of the equator, which affects temperature |
| elevation | how much above sea level an area is |
| Higher elevation | means lower temperatures because air gets cooler as it rises |
| Large bodies of water - oceans and large lakes | temps are usually milder because water heats and cools at a slower rate than on land |
| Hurricanes - Earth's biggest storms | are hundreds of kilometers wide with winds that can top 155 mph- miles per hour |
| Warm water and high humidity | feeds the storm |
| Hurricane watch | storm is still a couple of days away, it can hit that area or change paths |
