The Official Chapter 1 Quiz

Question 1 of 16

1

Earth's core...

Select one of the following:

  • 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

Explanation

Question 2 of 16

1

Identify the TRUE statement.

Select one of the following:

  • 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

Explanation

Question 3 of 16

1

Identify the FALSE statement. The big bang...

Select one of the following:

  • 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

Explanation

Question 4 of 16

1

The moho is the boundary between Earth's...

Select one of the following:

  • crust and mantle

  • inner and outer core

  • mantle and outer core

  • continental crust and oceanic crust

Explanation

Question 5 of 16

1

Which of Earth's layers accounts for the most volume of Earth?

Select one of the following:

  • The mantle

  • The lithosphere

  • The inner core

  • The crust

Explanation

Question 6 of 16

1

The geothermal gradient...

Select one of the following:

  • 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

Explanation

Question 7 of 16

1

Identify the False statement. The nuclear theory states that...

Select one of the following:

  • 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

Explanation

Question 8 of 16

1

Use the figure to describe the relationship between air pressure and altitude

Select one of the following:

  • 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

Explanation

Question 9 of 16

1

Which of the following statements about the crust is false?

Select one of the following:

  • 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

Explanation

Question 10 of 16

1

The two most common gases of the Earth's atmosphere are...

Select one of the following:

  • Carbon Dioxide (CO2) and Oxygen (O2)

  • Water (H2O) and Oxygen (O2)

  • Oxygen (O2) and Methane (CH4)

  • Nitrogen (N2) and Oxygen (O2)

Explanation

Question 11 of 16

1

Identify the FALSE statement. Differentiation of large planetesmals and protoplanets...

Select one of the following:

  • 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

Explanation

Question 12 of 16

1

Which of the following groups of elements makes up the most mass of the Earth?

Select one of the following:

  • Silicon, iron, potassium, sodium

  • Magnesium, iron, carbon dioxide, argon

  • Nitrogen, oxygen, helium, carbon dioxide

  • Iron, oxygen, silicon, magnesium

Explanation

Question 13 of 16

1

The current theory that explains the formation of our moon states that it...

Select one of the following:

  • 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

Explanation

Question 14 of 16

1

Identify the TRUE statement.

Select one of the following:

  • 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

Explanation
