Science CRCT Review

Unit 4, Unit 5, and Unit 6

Unit 4, Water in Earth's Processes

  • Underneath the ocean, the Earth has plains, mountains, and valleys, which are often larger than those on dry land.

  • Ocean currents can be caused by factors such as wind, salinity, temperature, the Coriolis Effect, and gravitational pull.

Unit 5, Weather and Climate

  • Ocean currents influence the weather in coastal areas. Currents can be caused by wind, differences in salinity, differences in water temperatures caused by uneven heating of the Earth, the Coriolis Effect which is a consequence of the Earth's rotation, and the gravitational pull of celestial bodies (tidal currents).

Unit 6, Universe and Solar System

The “Big Bang” is a theory of how the universe began.
