1. You and your family vacation at a cabin on the shore of a large lake. At night, you notice that a breeze blows over your cabin toward the lake. Explain what causes the wind to blow in that direction.

Answer: Land breezes are blowing from the land

to the ocean. The air over the ocean is warmer, so it rises up & the cool air from the land takes it places

2. Name the three types of fronts.

Answer: Warm Front, Cold Front, & Stationary Front

3. Climate is affected by what three things?

Answer: 1. Tilt and rotation of Earth 2. Latitudes

3. Landforms

4. How is weather different from climate?

Answer: Weather changes from day to day, whereas climate is an average over several years

5. How does a warm front occur? What type of weather is associated with this type of front?

Answer: A mass of warm air moves toward and over a slower mass of cold air

-As it is pushed up over cool air, it

cools & forms clouds

-Can cause steady rain for 1-2 days

6. Explain what a Rain Shadow is and how it forms?

Answer: Warm air cools as it rises along mountain creating clouds (loses moisture); Cool dry air from the mountain will then warm as it falls down the other side

-Air has less moisture because released it

on the other side -Creates deserts on

other side = Rain Shadow

7. What happens during an equinox? How many of these are there each year?

Answer: Day and Night are equal all over the Earth

There are two equinoxes per year:1. Spring: March 21st

2. Fall: September 22nd

8. How does a cold front occur? What type of weather is associated with this type of front?

Answer: Forward edge of a mass of cold air moves under a slower mass of warm air and pushes it up quickly (due to steepness) -High winds,

thunderstorms, & tornadoes can accompany front
