​

Uncover 1:

• tornadoes, hot, cold

• warm front, occluded, maritime

​Lesson 4 -
How do features on Earth’s surface affect the weather?

​What did we do?

​Uncover 1:
We observed what happened to bubbles being blown toward a “mountain”. We used our observations to complete a model.

1. While weather is short term, ​climate is a region's average weather over a long period.

2. ​The amount of sun at a given location is affected by Earth's tilt, movement, and shape.

3. ​Wind and water move heat around Earth, affecting how warm or wet a place is.

4. ​Mountains influence temperature and precipitation.

Weather & Climate

​

Multiple Choice

We saw that the temperature of the air mass ______ when the air mass’s elevation _____

• increased, decreased

• decreased, decreased

• increased, increased

• decreased, increased

​Weather is the temperature and precipitation at a specific time and place. Climate is a region’s average weather over a long period of time. Climate and weather are affected by the sun, location on Earth, wind, water, and mountains.

Understanding Weather & Climate

​

Multiple Choice

As the air mass' elevation increases, the water turns from _____ to ____ . That causes _____/_____/_____ .

• solid to liquid; evaporation

• gas to liquid; precipitation/rain/snow

• solid to liquid; sublimation

• solid to gas; condensation

The parts of Earth tilted toward the sun get more solar energy than the parts tilted away from the sun. This changes during the year, creating seasons. While some locations are having a warm summer, others are having a cold winter.

Sun and Location

​

Energy from the sun falls more directly on the equator, so that area has warm temperatures all year. It gets colder as you move away from the low latitude of the equator. The coldest areas are at the poles, the highest latitudes.

​

Uncover 2:
We examined a storm on Lake Erie and its effects. We completed a model to explain what happened.

Multiple Choice

We saw that when the air mass crossed the warm lake, its temperature _____ . The humidity of the air _____

• increased, increased

• decreased, decreased

• increased, decreased

• decreased, increased

Multiple Choice

When the air mass reached land again, the air temperature ______.

• stable

• increased

• decreased

• humid

Multiple Choice

Humidity in the air turned from ____ to ____ which caused massive amounts of _____ .

• gas, liquid, gas

• gas; solid, steam

• solid; solid, rain

• liquid; solid; snow

​

 What did we figure out?

Mountains also affect climate. The higher areas are colder than the lower elevations. Warm air blowing against a mountainside rises and cools. Clouds form, and precipitation falls on the side facing the wind. However, there is little moisture on the other side of the mountain. This effect creates a rain shadow, a dry area on the side of the mountain facing away from the direction of the wind.

Mountains

Multiple Choice

When an air mass interacts with _____ _____ , such as mountains, the air _____) and the temperature _____, causing _____ and a dryer resulting air mass. The air mass then descends and _____ , causing a _____ area.

• lower, lower, lower, raises, higher

• decreased elevation, lowers, decreases, precipitation, cools, dry

• increased elevation, rises, decreases, precipitation, warms, dry

• lower elevation, lowers, increases, snow, hotter, wet
