Which detail about Earth’s atmosphere is true?

• It has no effect on surface temperatures.

• It shields life forms on the surface from radiation.

• It allows meteors to strike the surface.

• It is thicker over places where there are high elevations.

The sun emits harmful ultraviolet radiation, some of which reaches Earth's surface. Scientists recommend that people who plan on being outdoors for at least 20 minutes apply sunscreen to protect their skin from ultraviolet radiation. What blocks most of the sun’s ultraviolet radiation from reaching Earth's surface?

• wind

• precipitation

• clouds

• atmosphere

What type of global wind is found at letter D?

• Doldrums

• Prevailing Westerlies

• Polar Easterlies

• Tradewinds

During a summer day on the beach, the sand on the beach and the air temperature feel hot, but the ocean water feels cold. This is because the land and air change temperature much faster than the ocean water, making the land and the air warmer than the ocean water. At night, why would the ocean water be warmer than the air?

• As a cool breeze blows off the water onto the land, the water warms up.

• The heat from the air transfers to the water during the night, making the water warmer than it was during the day.

• Air changes temperature faster than water, so the water is warmer and the air is much cooler than it was during the day.

• Air stays warmer longer than water so your body is warm when you jump into the water.

Justin and Angela are conducting an experiment to see ways different sources of water contribute to the water cycle. They evaporate water from the Atlantic Ocean and rainwater. They use the same amount of each and do the experiment under the same conditions. What will they observe?

• The salt water evaporates slower

• The rainwater does not evaporate

• Salt is left behind from both samples.

• Salt is left behind from the ocean sample
