100

What are areas where hot water and steam escape from the Earth called?

Hydrothermal features.

200

What type of eruptions result in gentle lava flows?

Effusive eruptions.

200

What are vertical structures that cut across existing rock layers?

Dikes.

200

What are the large, deep-seated plutons known as?

Batholiths.

200

On average, how much does the temperature increase per kilometer of depth?

About 30°C.

200

What is a natural pool of hot water known as?

Hot spring.

300

Higher content of what substance can lead to more explosive eruptions?

Silica.

300

Sills and dikes are formed from what type of volcanism?

Intrusive volcanism.

300

How do plutons typically form?

When magma cools slowly beneath the Earth's surface.

300

What can variations in the geothermal gradient indicate?

The presence of geothermal resources or volcanic activity.

300

What are eruptions of steam and hot water at regular intervals called?

Geysers.

400

What is the term for the thickness or resistance to flow of a liquid?

Viscosity.

400

What is the process called when magma intrudes into existing rock?

Intrusion.

400

What geological process can expose plutons at the surface?

Erosion and uplift.

400

Why is the geothermal gradient important for understanding volcanic processes?

It helps predict volcanic activity and geothermal energy potential.

400

In what type of regions are hydrothermal features commonly found?

Volcanic regions.

500

500

What is the significance of studying plutons in geology?

To understand underground processes and locate mineral deposits.

500

What is geothermal energy and how is it related to the geothermal gradient?

Energy derived from the Earth's heat, related to temperature increases with depth.
