Combined Review

If the Earth’s tilt on its axis increased, seasonal changes in temperature in mid-latitude regions would 

• decrease
• increase
• remain the same
• increase in summer but not winter

Regions in high latitudes receive less energy from the Sun than regions at the equator primarily because

• Sun's rays are less direct
• More light is reflected at higher latitudes
• the equator is closer to the sun than the poles
• an ozone hole is located at each pole

Which forces do scientists believe are responsible for the movement of Earth’s tectonic plates?

• ocean currents and trade winds
• rotation of Earth and the tides
• convection and gravity
• weathering and erosion

Which forces are responsible for the formation of soil?

• weathering and the decay of dead organisms
• tectonic plate movement and sea floor spreading
• ocean currents and trade winds
• the tides and annual changes in the Sun-Earth relationship

               ?    boundaries occur when two tectonic plates slide apart from one another

• transform
• divergent
• convergent
• subduction

               ?    boundaries occur when two tectonic plates slide towards one another

• transform
• divergent
• convergent
• subduction

Which term do scientists use to describe all living organisms interacting on Earth?

• hydrosphere
• lithosphere
• atmosphere
• biosphere

Which physical forces cause changes to Earth’s lithosphere?

• ocean currents and trade winds
• Earth’s rotation and revolution around the sun
• tectonic plate movement, weathering and erosion
• tidal changes and the moon’s orbit around the Earth

Which of the following typically occurs in the hydrosphere?

• the transformation of rock from sedimentary to metamorphic
• the circulation of hot and cold oceanic currents
• the regulation of the rate at which thermal energy leaves the planet
• A  the upward folding of continental plates to create mountains

Which two gases are primarily responsible for Earth’s natural greenhouse effect because of their ability to absorb energy and send it back to Earth?

• Oxygen and nitrogen
• Water vapor and carbon dioxide
• Ozone and argon
• Helium and hydrogen
