6th Grade 2.4 Earths Atmosphere

Which of the following describes how the stratosphere is important to life on Earth?

• It contains ozone which filters out the Sun's harmful rays.

• It blocks meteors falling from space and crashing to Earth.

• It allows solar heat to pass through and warm the ground below.

• It contains conditions that are favorable to jet streams which drive our weather.

Jamari was enjoying a day at the beach when he noticed storm clouds forming over the ocean. He wondered why this happened at the beach so often. Which of these statements answers Jamari's question?

• Cool ocean currents cause transpiration forming storm conditions in the atmosphere.

• Clouds evaporate more quickly over the ocean causing storms to form in the atmosphere.

• The land and the ocean are heated evenly causing ocean and air currents to form storms.

• The ocean water is constantly evaporating causing the atmosphere to be humid and storms to form.

Use the picture below to answer the following question.

• The ocean reflects the Sun’s rays into the atmosphere and causes the water vapor to condense into a cloud.

• The cooler temperature of the ocean causes the water to evaporate into the atmosphere to later form clouds.

• The Sun’s rays heat the ocean’s water and cause some of it to evaporate into the atmosphere to later form clouds.

• The warmer temperature of the ocean causes the water vapor to release into the atmosphere through condensation.

The image below shows some of the world's ocean currents. What conclusion can be made about how ocean currents can influence the local weather in San Francisco, California compared to Washington, D.C., during the summer?

• San Francisco temperatures are warmer than Washington, D.C., because Washington, D.C. is farther north than San Francisco.

• San Francisco temperatures are cooler than Washington, D.C., because Washington, D.C., is on the coast and San Francisco is inland.

• San Francisco temperatures are cooler than Washington D.C. because Washington, D.C. is located near warm ocean currents and San Francisco is near cool ocean currents.

• San Francisco temperatures are warmer than Washington, D.C., because Washington, D.C., is located near cool ocean currents and San Francisco is near warm ocean currents.

The weather map below shows the polar jet stream as it moves through the United States. Which statement best describes the temperature differences between two cities?

• Temperatures in Atlanta are colder than in Dallas because Atlanta is south of the jet stream.

• Temperatures in Eugene are colder than in Boston because Eugene is south of the jet stream.

• Temperatures in Orlando are warmer than in Dallas because Orlando is south of the jet stream.

• Temperatures in Portland are warmer than in Orlando because Portland is north of the jet stream.

The picture below shows two Florida cities and their temperatures on the same day of summer at the same time. Which of the following best describes why Orlando is much warmer than Merritt Island during the day in the summer?

• Merritt Island has a much smaller population than Orlando, so the lower amount of total body heat decreases its temperature.

• Cool dense air from the ocean moves onshore replacing the warm less dense air in Merritt Island resulting in a lower temperature.

• Cool dense air from Orlando moves towards the ocean replacing the warm less dense air in Merritt Island resulting in a lower temperature.

• The Sun sets in Merritt Island before it sets in Orlando, so Merritt Island has more time to cool off in the shade than Orlando, decreasing its temperature.

Which of the following statements accurately describes how temperature affects the cycling of water?

• Higher temperatures result in a decrease in both evaporation and precipitation.

• Higher temperatures result in an increase in both evaporation and precipitation.

• Lower temperatures result in a decrease in evaporation and increase in precipitation.

• Lower temperatures result in an increase in evaporation and decrease in precipitation.

How does the atmosphere support and protect life on Earth?

• It cools the land masses by producing carbon dioxide and heats the oceans evenly.

• It keeps the temperature on Earth balanced by both absorbing and reflecting heat from

  the Sun.

• The water vapor in the atmosphere cools the planet and helps form ocean currents and

  weather.

• The ozone layer protects planet Earth from acid rain and provides the oxygen we need to

  breathe.
