- Bis divided into two parts- lithosphere and asthenosphere
- Cgenerates Earth's magnetic field
- Dis the thinnest layer
2Identify the TRUE statement.
- AThe composition of the jovian planets is mainly gas and ice
- BThe sun accounts for almost 50% of the solar system's mass
- CThe only two planets with moons are Earth and Jupiter
- DOur sun is the only star we know that has planets associated with it
3Identify the FALSE statement. The big bang...
- Aoccurred more than 13 billion years ago
- Bbegan with all matter and energy concentrated in an infinitesimally small point
- Ctheory states that at the instant of explosion, everything had so much thermal energy even the smallest atomic pieces couldn't exist
- Dis the explanation for how our solar system was developed
4The moho is the boundary between Earth's...
- Acrust and mantle
- Binner and outer core
- Cmantle and outer core
- Dcontinental crust and oceanic crust
5Which of Earth's layers accounts for the most volume of Earth?
- AThe mantle
- BThe lithosphere
- CThe inner core
- DThe crust
6The geothermal gradient...
- ARefers to the rate of change in temperature with depth in the Earth
- BIncreases as you go into the Earth
- CAverages about 5 degrees celcius per km in the upper crust
- DStates that temperatures near the mantle-core boundary may exceed the temperature of the sun
7Identify the False statement. The nuclear theory states that...
- Aas the universe cooled, atoms and molecules accumulated in patchy clouds of gas called nebulae
- Bnebulae condensed and heated to become spinning accretion disks
- Cas density increases due to more gas being crammed into a small space, temperature cools
- Dgravity caused the inward collapse of dense gas to form protostars
8Use the figure to describe the relationship between air pressure and altitude
- AAir pressure increases linearly with altitude
- BAt the top of mount Everest, air pressure is less than .4 bar
- CAir pressure increases above .6 bar at an altitude less than 7 km
- DAt the altitude that commercial jets fly, air pressure is higher than 1 bar
9Which of the following statements about the crust is false?
- AThe crust is the top of the mantle that has cooled and hardened
- BThe crust and the upper part of the mantle make up the lithosphere
- CThe thickness of crust can vary from -1 km up to 70 km thick
- DThere are two different types of crust- oceanic and continental
10The two most common gases of the Earth's atmosphere are...
- ACarbon Dioxide (CO2) and Oxygen (O2)

11Identify the FALSE statement. Differentiation of large planetesmals and protoplanets...
- Awas caused by heat created by transformation of kinetic energy from collisions into thermal energy
- Bwas inhibited by the presence of radioactive elements because their decay absorbs heat from their surroundings
- Cbegan with heating up component materials within their bodies
- Dis the process by which these bodies develop internal layering

- BWas a separate small planet before it was captured by Earth's gravity
- Cwas formed by the collision of Earth with mars-sized protoplanet
- Dspun off the fast-spinning Earth during early formation of the solar system
14Identify the TRUE statement.
- AIgneous rocks form when preexisting rocks undergo changes in heat and pressure
- BHot molten rock that cools and hardens produces metamorphic rocks
- CSedimentary rocks form when preexisting rock grains are cemented together
- DMagma is the term for very hot rock that is molten;when it cools and hardens it's called lava
15Choose the list that accurately shows rock composition decreasing in silica and increasing in magnesium and iron.
- AGranite, peridotite, basalt
- BGranite, basalt, peridotite
