Resource summary

Question 1

Question
Earth's core...
Answer
  • is under such intense pressure that it's made of Iron
  • is divided into two parts- lithosphere and asthenosphere
  • generates Earth's magnetic field
  • is the thinnest layer

Question 2

Question
Identify the TRUE statement.
Answer
  • The composition of the jovian planets is mainly gas and ice
  • The sun accounts for almost 50% of the solar system's mass
  • The only two planets with moons are Earth and Jupiter
  • Our sun is the only star we know that has planets associated with it

Question 3

Question
Identify the FALSE statement. The big bang...
Answer
  • occurred more than 13 billion years ago
  • began with all matter and energy concentrated in an infinitesimally small point
  • theory states that at the instant of explosion, everything had so much thermal energy even the smallest atomic pieces couldn't exist
  • is the explanation for how our solar system was developed

Question 4

Question
The moho is the boundary between Earth's...
Answer
  • crust and mantle
  • inner and outer core
  • mantle and outer core
  • continental crust and oceanic crust

Question 5

Question
Which of Earth's layers accounts for the most volume of Earth?
Answer
  • The mantle
  • The lithosphere
  • The inner core
  • The crust

Question 6

Question
The geothermal gradient...
Answer
  • Refers to the rate of change in temperature with depth in the Earth
  • Increases as you go into the Earth
  • Averages about 5 degrees celcius per km in the upper crust
  • States that temperatures near the mantle-core boundary may exceed the temperature of the sun

Question 7

Question
Identify the False statement. The nuclear theory states that...
Answer
  • as the universe cooled, atoms and molecules accumulated in patchy clouds of gas called nebulae
  • nebulae condensed and heated to become spinning accretion disks
  • as density increases due to more gas being crammed into a small space, temperature cools
  • gravity caused the inward collapse of dense gas to form protostars

Question 8

Question
Use the figure to describe the relationship between air pressure and altitude
Answer
  • Air pressure increases linearly with altitude
  • At the top of mount Everest, air pressure is less than .4 bar
  • Air pressure increases above .6 bar at an altitude less than 7 km
  • At the altitude that commercial jets fly, air pressure is higher than 1 bar

Question 9

Question
Which of the following statements about the crust is false?
Answer
  • The crust is the top of the mantle that has cooled and hardened
  • The crust and the upper part of the mantle make up the lithosphere
  • The thickness of crust can vary from -1 km up to 70 km thick
  • There are two different types of crust- oceanic and continental

Question 10

Question
The two most common gases of the Earth's atmosphere are...
Answer
  • Carbon Dioxide (CO2) and Oxygen (O2)
  • Water (H2O) and Oxygen (O2)
  • Oxygen (O2) and Methane (CH4)
  • Nitrogen (N2) and Oxygen (O2)

Question 11

Question
Identify the FALSE statement. Differentiation of large planetesmals and protoplanets...
Answer
  • was caused by heat created by transformation of kinetic energy from collisions into thermal energy
  • was inhibited by the presence of radioactive elements because their decay absorbs heat from their surroundings
  • began with heating up component materials within their bodies
  • is the process by which these bodies develop internal layering

Question 12

Question
Which of the following groups of elements makes up the most mass of the Earth?
Answer
  • Silicon, iron, potassium, sodium
  • Magnesium, iron, carbon dioxide, argon
  • Nitrogen, oxygen, helium, carbon dioxide
  • Iron, oxygen, silicon, magnesium

Question 13

Question
The current theory that explains the formation of our moon states that it...
Answer
  • Coalesced from gas and dust in its current place next to Earth
  • Was a separate small planet before it was captured by Earth's gravity
  • was formed by the collision of Earth with mars-sized protoplanet
  • spun off the fast-spinning Earth during early formation of the solar system

Question 14

Question
Identify the TRUE statement.
Answer
  • Igneous rocks form when preexisting rocks undergo changes in heat and pressure
  • Hot molten rock that cools and hardens produces metamorphic rocks
  • Sedimentary rocks form when preexisting rock grains are cemented together
  • Magma is the term for very hot rock that is molten;when it cools and hardens it's called lava

Question 15

Question
Choose the list that accurately shows rock composition decreasing in silica and increasing in magnesium and iron.
Answer
  • Granite, peridotite, basalt
  • Granite, basalt, peridotite
  • Peridotite, basalt, granite
  • Basalt, peridotite, granite

Question 16

Question
Identify the FALSE statement.
Answer
  • The Earth has both magnetic and geographic poles
  • Earth's magnetic field is dipole
  • The sun's stellar wind distorts magnetic field into teardrop shape
  • Region inside the Earth's magnetic shield is the biosphere
