Most minerals do not split apart evenly in flat sheets. Instead they have a characteristic type of

At an oceanic-oceanic divergent boundary, where is the newest crust?

Rock that forms from the cooling of magma below the surface or lava that cools on Earth's surface is called

Earth's inner core is

The place where two plates come together is know as a

After scientists analyze the results of their experiments, they

The contour lines that represent the top of a hill form

The term used to describe how a mineral reflects light from its surface is

The formation of the Hawaiian Islands is one example of

It would be easy to walk up a slope represented by contour lines that

A mineral must have formed in nature, have a definite chemical makeup, and

Every experiment must have only one independent variable.

Earth's magnetic field results from the spinning of the

Maria designed an experiment to determine whether water or land gets hotter in the sun. She set up a pan of water and a pan of soil, each with a thermometer in it. She placed the pans in the sun for ten minutes and measured the temperature in each pan once every minute. What was the dependent variable in the experiment?

The process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle is known as

What type of earthquake wave cannot travel through liquids?

The first step in the scientific method is testing the hypothesis.

Most geologists rejected Alfred Wegener's idea of continental drift because

What type of force is occurring at a strike-slip fault?

What kind of slope do closely spaced contour lines indicate?

In what direction do seismic waves carry the energy of an earthquake?

"There are 2 pencils on the desk" is an example of a qualitative observation.

Which of the following is a quantitative observation?

Why is replication of experiments an important part of the scientific process?

What is Pangaea?

Most geologists think that the movement of Earth's plates is caused by

According to Wegener's hypothesis of continental drift

Which movement best describes a strike-slip fault?

Before lava reaches the surface it is called

The geologic theory that states that pieces of Earth's lithosphere are in constant, slow motion is the theory of

A collision between two pieces of continental lithosphere at a convergent boundary produces a

Derrick wants to conduct an investigation to determine which liquid detergent cleans clothes best. What tools will he need to conduct his investigation?

The color of a minerals' powder is called its

A place where two plates slip past each other, moving in opposite directions, is known as a

A mineral with a hardness of 6 will scratch a mineral with a hardness of more than 6.

Which type of evidence was NOT used by Alfred Wegener to support his continental drift hypothesis?

A rock that contains a metal or other valuable mineral is called a(n)

Liquid magma flows upward through cracks in rock because it is

In a controlled experiment, a scientist is studying how long it takes parachutes of different sizes to fall to the ground. What is the independent variable?

Which skill are you suing when you use your five senses to gather information?

In the process of sea-floor spreading, where does molten material rise from the mantle and erupt?

At which boundary do deep-ocean trenches occur?

Igneous rock that formed from lava that erupted onto Earth's surface is called

How do geologists observe Earth's interior?

Earth's mantle is

Compaction and cementation can change sediments from igneous rocks to metamorphic rock.

Scientists think that convection currents flow in Earth's

Heat and pressure deep beneath Earth's surface can change any rock into

What is the order of Earth's layers least dense to most dense?
