Chapter 4: Earth & It's Moon

1. 1The density of water in Earth's hydrosphere and the density of rocks in the crust are both [blank_start]lower[blank_end] than the average density of the planet as a whole.

   1. Alower
   2. Bhigher
2. 2The Earth's [blank_start]atmosphere[blank_end] is composed primarily of nitrogen and oxygen.

   1. Aatmosphere
   2. Bmagnetosphere
3. 3The Earth's [blank_start]magnetosphere[blank_end] is a zone of charged particles trapped by a planet's magnetic field, lying above the [blank_start]atmosphere[blank_end].

   1. Amagnetosphere
   2. Batmosphere
4. 4The daily [blank_start]tides[blank_end] in Earth's oceans are caused by the gravitational effects of the Moon and the Sun, which raise tidal [blank_start]bulges[blank_end] in the oceans.

   1. Atides
   2. Bbulges
5. 5Because of tidal forces, the Moon is tidally locked to Earth.

   1. AVerdadero
   2. BFalso
6. 6Motion of Earth's crustal plates is driven by convection in Earth's upper mantle.

   1. AVerdadero
   2. BFalso
7. 7Lunar maria are extensive lava flow regions.

   1. AVerdadero
   2. BFalso
8. 8Most large surface features on the Moon formed billions of years ago.

   1. AVerdadero
   2. BFalso
9. 9Like Earth, the Moon has a large molten iron core.

   1. AVerdadero
   2. BFalso
10. 10Earth's magnetic field is the result of our planet's large, permanently magnetized iron core.

    1. AVerdadero
    2. BFalso

11. 11The Moon's magnetic field is about 100 times weaker than Earth's.

    1. AVerdadero
    2. BFalso
12. 12If you were making a scale model of Earth, representing our planet by a 12 inch basketball, the inner core would be about the size of

    1. Aa half-inch ball bearing
    2. Ba 2 inch golf ball
    3. Ca 4 inch tangerine
    4. Da 7 inch grapefruit
13. 13Earth's average density is about the same as that of

    1. Aa glass of water
    2. Ba heavy iron meterorite
    3. Can ice cube
    4. Da chunk of black volcanic rock
