Water Cycle Interactions

The Earth is unevenly heated. Some parts of Earth are hotter than others, because -

• Volcanic eruptions only occur in certain areas

• Some parts of the Earth are closer to the Sun

• Earth is a sphere with a tilted axis

A student predicts that warmer ocean waters will have more evaporation and humidity than cooler ocean waters. Is her prediction correct?

• Yes.

  The rate of evaporation is directly related to water temperature.

• Yes.

  Warmer water causes more thermal energy to evaporate.

• No.

  Liquid water can only absorb a small amount of heat.

• No.

  The rate of evaporation isn't related to water temperature.

When liquid water in the ocean evaporates, it changes its state of matter and becomes -

• Water droplets

• Water vapor

• Clouds

• Water dioxide

Molecules of water vapor change their state of matter and become liquid water molecules when -

• They are heated up

• They touch other molecules of water vapor

• They cool down

• They reach a certain age in the atmosphere

Condensation occurs in the water cycle when -

• Water vapor in the atmosphere cools down

• Thermal energy from the Sun heats water

• Liquid water turns into a cloud

Condensation in the water cycle is visible as -

• Oceans, lakes, and rivers

• Rain, snow, sleet, or hail

• Clouds and fog

• Wind

In the water cycle, water vapor condenses into liquid water molecules and forms clouds.

What are TWO events that would cause this?

• Warm, humid air rises high into the atmosphere and gets colder

• The energy and force of multiple lightning strikes in areas with high humidity

• A cold air mass (cold front) moves into an area with warm, humid air

As more and more water molecules collect together in clouds, they form -

• Large and small pieces of hail

• Small water droplets

• Wind gusts that travel hundreds of miles

• Grains of grey and black dirt

Precipitation occurs when -

• Clouds get too heavy and fall down

• Water droplets in clouds get too heavy and fall

• Water vapor changes into liquid water molecules

• Water vapor falls down
