2. EARTH SCIENCE REVIEW

3. Characteristics of the moon Spherical; made of rock Has no atmosphere, no water, and no living things Drastic temperature changes Earth’s natural satellite

4. Moon and its effects One- fourth of the Earth’s diameter revolves around the earth every 29 1/2 days the gravity of the moon controls the tides

5. Types of tides Spring tides- gravity of the sun and moon work together (tide is high) Neap tides- gravity of the sun and moon PULL against each other (tide is low)

6. Phases of the moon New moon Crescent First quarter Gibbous Full moon Gibbous Third Quarter Crescent New moon

7. Moon Phases

8. Eclipses Solar eclipse- sunlight is blocked by the moon Lunar eclipse- Earth is between the sun and moon Moon is visible because of reflected sunlight

9. Characteristics of the sun Made of plasma (high energy form of matter) Produces energy as a result of nuclear fusion Core temperature (15,000,000 ºC)

10. The Sun 150,000,000 kilometers from Earth Makes up 99% of the mass of our solar system

11. I bet you know the answers! What causes day & night? Which one is bigger the earth or the moon? Where does the moon get its light from? What percent of the earth is always lit by the sun? How many stars are in our solar system? How many days does it take for the Earth to revolve around the sun? How many low and high tides on Earth every 24 hours?

12. Earth Science Question on rotation What is rotation? (define) The rotation of the Earth on its axis causes- –Adays –Bmonths –Cseasons –Dyears

13. Rotation causes day & night. Rotation is the turning or spinning of the Earth in one place on its imaginary axis. Rotation of the earth on its axis causes day & night. (answer A).

14. Earth Science Question: Which of these shows the location of a polar ice cap? Which of these shows the location of the equator?

15. Polar ice caps= A Equator= C

16. The Rock Cycle Thinking about relationships among the major rock groups

17. sedimentary rocks sediment metamorphic rocks igneous rocks magma cooling, crystallization weathering and erosion compaction, cementation melting high temperature great pressure

18. Major Rock Groups Igneous –Formed from a melt (molten rock) –Intrusive: slow cooling and crystallization –Extrusion: quick cooling at the surface Sedimentary –Formed at the Earth’s surface –This is where fossils are found – (Mineral Fragments or grains, clays) –ChemiClasticcal (crystalline chemical/biochemical precipitates) Metamorphic –Changed by pressure, temperature and fluids.
