What is unique about the rotation of the sun?

• It spins way faster than the planets.

• It spins extremely slow.

• The top half spins one direction and the bottom half spins the opposite direction.

• Some areas spin faster than others.

Conduction is one way in which energy in the form of heat is transferred through the Earth system. Which of the following best describes how conduction causes magma to heat the surrounding rock inside Earth?

• The warm magma flows towards Earth’s surface and cools.

• Electromagnetic waves from the sun warm the magma, which in turn warms the surrounding rock

• Differences in the density of the magma cause movement in the magma, which warms the surrounding rock

• Molecules of magma collide with molecules of rock and transfer energy as heat

Electromagnetic waves produced by the sun travel through space to Earth. What is this method of energy transfer called?

• CONVECTION

• CONDUCTION

• INSULATION

• RADIATION

Earth’s atmosphere is not uniform in temperature. What is the primary method by which energy as heat can be rapidly transferred and cycled through different elevations in Earth’s atmosphere?

• convection

• conduction

• insulation

• radiation

Solar energy does not warm Earth’s surface evenly. For example, during the day, land areas warm up faster than nearby bodies of water. How does this uneven warming affect the movement of air over land and water?

• The cooler, denser air above the water flows toward the warmer, less dense air above the land, causing a sea breeze.

• The warmer, less dense air above the land flows toward the cooler, denser air above the water, causing a land breeze.

• The cooler air over the water would absorb water vapor and rise, resulting in rainy conditions over the shoreline.

• The warmer air over the land would transfer energy to the cooler air by conduction, leading to a uniform air temperature.

Sunlight does not reach all parts of Earth's surface equally. This results in uneven heating of Earth’s surface and the formation of wind. Why does the uneven heating of Earth's surface produce wind?

• It causes condensation in the atmosphere.

• It causes pressure differences in the atmosphere.

• It causes differences in the level of water vapor in the atmosphere.

• It causes cooler air to rise, creating a partial vacuum near the surface.

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

The atmosphere serves as a buffer between Earth and the sun. Which of the following wavelengths of electromagnetic radiation are absorbed by the ozone layer?

• X-rays

• infrared radiation

• radio waves

• ultraviolet radiation

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.
