What will occur when the sun, moon, and Earth are aligned in a relatively straight line?

• a decrease in global wind patterns

• an increase in temperature near the equator

• more earthquakes near the equator and fewer at the poles

• a larger-than-normal height difference between low tide and high tide

How does the energy produced by the sun travel to earth?

• by the magnetic fields between the sun and Earth

• by convection of heat through particles in space

• by the radiation of electromagnetic waves through space

• by the process of conduction of heat between the sun and Earth

How does energy from the sun help to maintain life on earth?

• it heats Earth's atmosphere and surface

• it forms the ocean's water and oxygen in the atmosphere

Which best explains the shape of Earth?

What would be most effective in minimizing the potential damage caused by an earthquake?

• installing sirens in area prone to earthquakes

• building structures that withstand ground vibrations

• increase the amount of concrete during road building

• requiring the recycling of metal and wood products

What can best be concluded from the information: bedrock that is closer to oceanic ridges is younger in age than bedrock that is farther away?

• the shape of Earth's lithosphere is continually changing

• the movement of continental plates is caused by volcanic eruptions

• the oceans are becoming deeper and warmer as more rocks are produced

• the rocks on the ocean floor are producing tectonic plates that are converging
