Earth Interior

Brittle

At temperatures characteristic of the lithosphere, alimunosilicate minerals are?

Alumino-silicates

Which minerals make up most of the lithosphere?

Silica, Magnesium, and Iron

A geologist studies an ocean volcano producing oceanic crust. Though he cannot sample the rock,what can he infer is the dominant composition of the rocks?

Crust

Which is the outermost compositional layer of Earth?

Outer Core

Which layer of Earth's Interior is liquid

Continental crust, oceanic crust and the uppermost part of the mantle

Which of the following best describes the makeup of the lithosphere?

The mesosphere is warmed primarily by heat that moves up from the stratosphere; therefore, higher regions of the mesosphere are cooler than the lower regions

Which of the following best explains the relationship between temperature and altitude in the mesosphere?

The outer core is liquid and the inner core is solid

Which statement best describes Earth's core?

It is too deep inside Earth to reach by drilling.

Which statement best describes why scientists cannot study Earth's inner core directly?

When Earth was still molten, gravity pulled dense elements down to Earth's center/

Which statement best explains why Earth's core contain such high percentages of iron and nickel?

The brittle lithosphere cracks under pressure from the moving asthenopshere

Which statement best explains why Earth's lithosphere is broken into tectonic plates?

Metallic

Which term best describes the composition of Earth's core?

Seismic Waves

Which type of waves give scientists information about the structure of Earth's interior layer?

They have similar textural properties

Why do geologists consider Earth's continental crust oceanic crust, and upper mantle to form a single structural layer?

They exist in different states of matter.

Why do scientist divide Earth's core into an outer and inner core?

The mantle

A geologist discovers a rock on a volcanic island that consists mostly of magnesium oxide. Where did this rock most likely originate?

Iron and nickel

Early Earth was a pool of molten metals. What metals sank to Earth's center to form the core?

A tectonic plate

Geologist classify a certain section of Earth as lithosphere. Which of the following could it be?

Certain seismic waves that travel only through solids produce shadow zones in different parts of the globe.

How did scientist determine that the outer is a liquid?

They would detect a physical change from party molten rock to solid rock

If scientist could bore though Earth's Interior, what change would they most likely notice as they passed from the asthenosphere to the mesosphere?

Asthenoshpere

In which layer of Earth does convection occur?

Mantle

In which layer of the geosphere does the asthenosphere lie?

False

Incredible temperature and pressure cause most Earth's mantle to be liquid rock.

Both Continental and Oceanic Crust

Most tectonic plates contain?

Intense Pressure

No scientist has ever sampled the inner core. However, geologists know the inner core is solid because it experiences

A mountain in the middle of a continent

Rocks form which source would most likely contain the highest percentage of silicate minerals?

The ocean floor

Rocks from which source would most likely contain the highest percentage of iron-bearing minerals?

Tectonic Plates

The earth's crust is divided into large slabs of rock that drift and collide together. These slabs of rock are known as?

The increase in temperature within Earth

The geothermal gradient describes?

Mantle Convection

The heat transfer process caused by the uneven distribution of thermal energy in Earth's interior is called?

the asthenosphere and the outer core.

The mesosphere shares a boundary with?

Composition, density differences, and temperature differences

What caused Earth's interior to separate into distinct layers?

They have similar textures(brittle)

What do the lithosphere and upper mantle have in common?

The lithosphere is rigid and the asthenosphere is flexible

What is the main difference between the lithosphere and the asthenosphere?

The Asthenosphere

What is the partly molten layer beneath Earth's lithosphere?

The transfer of thermal energy from Earth's surface toward its core

What process drives mantle convection?

the rotation of Earth's crust

What produces Earth's magnetic field?

An earthquake

When tension store in the Earth's crust is suddenly released, it causes?

The lower mantle

Where is the mesosphere locate inside the Earth?

Spherical

Which best describes the shape of the Earth's inner core?

Lithosphere

Which is Earth's outermost structural layer?

Lithosphere, Asthenosphere, Mesosphere,outer core, inner core

Which is the correct order of Earth's structural layers, form top to bottom?
