How does Layer Z protect life on Earth?

• It reflects most light away from Earth's surface so that it does not damage plants and animals.

• It holds a lot of neon gas, which is required by the circulatory system of plants and animals.

• It contains insulating water vapor that is circulated and returned to Earth's surface.

• It contains mostly ozone, which makes this layer the warmest for living organisms.

Chantal is creating a diagram showing the layers of Earth's atmosphere. She wants to show the location of the ozone layer on her diagram. Where should Chantal place the label for the ozone layer?

• in the troposphere

• in the stratosphere

• in the mesosphere

• in the thermosphere

Which layer of the atmosphere is being described in the passage?

• the mesosphere

• the stratosphere

• the thermosphere

• the troposphere

The data was most likely recorded from which atmospheric layer?

• A) troposphere

• B) stratosphere

• C) mesosphere

• D) thermosphere

In which two layers of the atmosphere does temperature increase as altitude increases?

• the mesosphere and stratosphere

• the stratosphere and thermosphere

• the thermosphere and troposphere

• the troposphere and mesosphere

The pictures show a greenhouse and Earth's atmosphere. How are a greenhouse and Earth's atmosphere most alike?

• Both contain large amounts of carbon dioxide.

• Both lower the temperature to be suitable for life.

• Both trap heat inside and prevent it from escaping.

• Both prevent harmful radiation from reaching Earth.

A student designs an experiment to study whether land or water holds heat longer. She takes two paper cups and labels them 1 and 2. She fills cup 1 with water at room temperature and cup 2 with sand to the same height. She inserts a thermometer into each cup. What is the next step she should perform?

• place both the cups in a tub of ice water

• place both the cups in a tub of warm water

• place cup 1 in a tub of ice water and cup 2 in a tub of warm water

• place cup 1 in a tub of warm water and place cup 2 in a tub of ice water

What causes coastal regions to have a narrower temperature range than regions that are farther inland?

• A) Clouds warm and cool much more slowly than land or water, insulating the land on the coasts.

• B) Air warms and cools much more slowly than water or land, insulating the land on the coasts.

• C) Water warms and cools much more slowly than land or air, insulating the land on the coasts.

• D) Land warms and cools much more slowly than water or air, insulating the land on the coasts.

• radiation

• refraction

• reflection

What is the most likely explanation for why the temperatures in location 1 and location 2 are different?

• The thermometer at location 2 is in water, and water absorbs heat slower than land.

• The thermometer at location 2 is on land, and land absorbs heat slower than water.

• The thermometer at location 1 is in water, and water absorbs heat slower than land.

• The thermometer at location 1 is on land, and land absorbs heat slower than water.
