Luis is comparing two stars in the Milky Way galaxy. How can Luis tell which star has the greater temperature?

• brightness

• apparent magnitude

• color

• absolute magnitude

The Sun does not have the greatest absolute brightness compared to stars in the night sky. How is it possible that it has the greatest apparent brightness?

• It is hotter than the other starts.

• It is closer than the other stars.

• It is farther away than the other stars.

• Apparent brightness is more powerful than absolute brightness.

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.

In which layer of the sun does nuclear fusion take place?

• Core

• Radiative zone

• Chromosphere

• Corona

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.
