Semester 1 Review HW

Front

What is a subduction zone?

Back

A subduction zone is a region where one tectonic plate sinks below another, typically occurring at convergent plate boundaries.

Front

What geological feature is commonly associated with transform boundaries?

Back

Earthquakes are the geological features most commonly associated with transform boundaries.

Front

What human activity has the greatest negative impact on ocean ecosystems?

Back

Commercial fishing to provide food for humans has the greatest negative impact on the balance of organisms within ocean ecosystems.

Front

What type of weather is indicated by clear, sunny skies?

Back

Clear, sunny skies typically indicate stable weather conditions with little to no precipitation.

Front

Define tectonic plates.

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with one another, causing geological activity.

Front

What is the difference between convergent and divergent boundaries?

Back

Convergent boundaries occur where tectonic plates move towards each other, while divergent boundaries occur where plates move apart.

Front

What is the primary cause of earthquakes?

Back

Earthquakes are primarily caused by the movement of tectonic plates along faults.

Front

What is a volcanic eruption?

Back

A volcanic eruption is the release of magma, gas, and ash from a volcano, often occurring at convergent or divergent boundaries.

Front

What is the role of ocean currents in marine ecosystems?

Back

Ocean currents help distribute nutrients and regulate temperatures, playing a crucial role in marine ecosystems.

Front

What is the significance of mapping the ocean floor?

Back

Mapping the ocean floor helps scientists understand geological features, marine habitats, and the effects of human activities.
