And Water Cycles

OH MY!! OH MY!!!

How much of Earth’s Surface is covered by water?

3/4

What is the difference in ocean water and fresh water?

Oceans are salty Fresh water is not.

What role does the sun play in the water cycle?

Water evaporates in the sun’s warmth

When moist air rises what happens?.

The moist air cools, and the water vapor condenses into clouds

Define condensation.

Water vapor becoming liquid water as it cools

What instrument do scientist use to measure air pressure?

Barometer

Define Humidity.

The amount of water in the air

You often see clouds along a cloud front, why?

The water vapor in the warm air mass cools and condenses into clouds

How fast do winds need to be for a storm to be declared a hurricane? 119 km/h

Winds exceeding 119 Km/hr

Where do tropical storms get their energy? Warm ocean water

What are the conditions in a hurricanes eye? The winds are gentle, and there is no rain.

The winds are gentle, and there is no rain.

What damage does a storm surge cause?

A storm surge can increase flooding

What do hurricane models predict?

The path of a hurricane

What information do scientist use to classify tornados on the Fujita scale?

Amount of damage and wind speed

What should a person do when a tornado warning is given?

Immediately take cover in a safe location such as a basement

How are tornados and hurricanes alike?

They both have dangerous winds

Explain and describe the water cycle. Precipitation Storage Condensation Evaporation

The water cycle is the movement of water between Earth’s surface and the atmosphere. When air cools, the water drops back to Earth as precipitation. Precipitation Storage Condensation evaporation

Hurricanes form several predictable stages. Name 3 stages of hurricane development

Stages of hurricane development include tropical depression, tropical storm, and hurricane.

Describe the characteristics of hurricane development A hurricane begins as a tropical depression during which a low pressure forms over warm ocean water and thunderstorms form. Winds blow at up to 61km/hr A tropical storm develops when winds exceed 62km/hr. Thunderstorms move in spiral bands toward the area of low pressure in the center. Air pressure drops even lower and wind speeds increase. A hurricane forms when wind speeds exceed 119km/hr

Describe two ways that hurricanes cause damage and two ways tornados cause damage.

Hurricanes- cause severe flooding and can cause mudslides or wind damage. Tornados- damage everything in their path. They can pick up objects like cars and smash them to the ground.
