Semester 2 Science Review

What type of plate boundary is shown below?

This is the location on Earth's surface directly above an earthquake's focus

The preserved remains or evidence of past living organisms

This is the numerical age (in years) of a rock or object.

According to the map, which state listed below has the greatest earthquake activity?

The lithosphere is the cold and rigid outermost layer of Earth.

Atoms of the same element that have different numbers of neutrons

Convection is the transfer of thermal energy by the movement of particles from one part of a material to another.

A surface where rock has eroded away, producing a break, or gap in the rock record.

This layer of Earth is found below the lithosphere. It is so hot that it behaves like a plastic material

Mountain ranges in the middle of the ocean are called:

Lava is molten rock beneath Earth's surface.

These two plates are separating. What type of plate boundary is this?

The largest number of individuals of one species that an ecosystem can support over time:

Large volcanic depression formed when a volcano's summit collapses or is blown away by explosive activity.

The development of desertlike conditions due to human activities and/or climate change

Alfred Wegener proposed the Continental Drift Theory. Why was his idea rejected?

This is a large, steep sided volcano made from a mixture of andesitic and rhyolitic lava and ash.

What is the order of rock layers from oldest to youngest?

Removal of large areas of forests for human purposes

A transform plate boundary forms where two plates slide past each other.

In this process, new oceanic crust forms along a mid-ocean ridge and older oceanic crust moves away from the ridge:

The time required for half of the amount of a radioactive parent element to decay into a stable daughter element

This is a vent in Earth's crust through with molten rock flows

Who proposed the hypothesis of continental drift?

Fertilizers used in agriculture increase the amount of nitrogen in the environment.

Molten rock stored beneath Earth's surface is called magma.

Pollution from several widespread sources that cannot be traced to a single location:

Small steep-sided volcano; made from moderately explosive eruptions of basaltic lavas

Pollution from a single source that can be identified:

Reforestation is a process in which mined land must be recovered with soil and replanted with vegetation.

This is a fossil copy of an organism made when a mold of the organism is filled with sediment or mineral deposits.

Pangaea is the name given to a supercontinent that began to break apart approximately 200 million years ago

This is a large, shield shaped volcano with gentle slopes made from basaltic lava

These plates are sliding past one another. What type of plate boundary is this?

All the organisms of the same species that live in the same area at the same time

The process in which the denser plate sinks below the more buoyant plate at a convergent plate boundary is called:

Divergent plate boundaries form where two plates collide.

A location inside Earth where rocks first move along a fault and from which seismic waves originate:

The process by which an unstable element naturally changes into another element that is stable.

Vibrations caused by the rupture and sudden movement of rocks along a break or a crack in Earth's crust
