Density is defined as:

Layers that are separated.

The speed at which a liquid moves

The weight of substance

Mass per unit of volume

What was the first evidence that suggested the Earth's crust might be broken into pieces?

Echo soundings aboard the Meteor

Plotting of deep earthquakes in the Pacific Ring of Fire

Radimetric dating

Radioactive decay

What substance was able to show previous orientations of Earth's magnetic field?

Magma

Basalt

Magnetite

Magnesium

What type of wave causes the most damage to property during an earthquake?

Primary waves

Secondary Waves

Surface Waves

Body Waves

Who is responsible for the theory of continental drift?

Francis Bacon

Sir Ernest Shackleton

Alfred Wegener

Antonio Snider-Pellegrini

What characteristic is associated with convergent plate boundaries?

New crust formation

Solidification of crust materials

Violent geological activity

Spreading zones

What is considered to be the densest type of crust?

Basalt

Continental crust

Granite

Andesitee

The sustained heat within the Earth's interior is attributed to:

Radioactive decay

Conduction

Convection

Isostatic equilibrium

Why do transform faults form?

They form due to remnants of convergent boundaries.

They form as results of secondary seismic waves.

They form due to lithospheric plate subduction zones.

They form because the axis of seafloor spreading across the surface of the Earth cannot follow a straight line smoothly.

What specifically connects the continental shelves to the deep-ocean floor?

Continental rise

Continental slope

Shelf break

Submarine canyon

What type of margin is generally steep?

Passive margin

Active margin

Continental margin

Shelf breaks

Atlantic ocean

Pacific ocean

Indian ocean

Southern ocean

How long is it estimated to take the ocean's volume of water to circulate through the oceanic crust at spreading centers?

1 mil years

10 mil years

100 mil years

100 bul years

What offsets the mid-Atlantic ridge's movement at fairly regular intervals?

Hydrothermal vents

Cooling lithosphere

Transform faults

Seamounts

What is a characteristic of transform faults?

They are fractures along two plates that slide vertically

They move in opposite directions, horizontally of each other

All of these choices are true.

What process explains how hydrothermal vents are created?

Fracture zones

Conduction

Convection

Pressure

What is the flatness of abyssal plains associated with?

The large amounts of sediment

The depth of abyssal plains

The pressure above the abyssal plains

The lack of sediment

What is a characteristic of the water that is expelled from hydrothermal vents?

The water is colder than when entering the vent

The water is enriched with metals.

The water has higher concentrations of organic material

The water has lower concentrations of dissolved gases

Despite the various attempts of land and ocean drilling, there has been no success in reaching the interior of the Earth.

True

False

Radiometric dating was used to age the ocean floor which was found to be older than the land at the center of continents.

True

False
