Missed J-Lab Questions

Front

What is a geyser?

Back

A geyser is a natural hot spring that intermittently ejects a column of hot water and steam into the air, typically caused by underground water being heated by hot igneous rock.

Front

What is metamorphism?

Back

Metamorphism is the process by which rocks are changed into different types of rocks due to heat, pressure, and chemically active fluids.

Front

What is the purpose of using a streak plate in mineral identification?

Back

A streak plate is used to determine the color of a mineral in powdered form, which helps in identifying the mineral.

Front

What is a contour map?

Back

A contour map is a representation of a three-dimensional surface on a two-dimensional plane, showing elevation changes using contour lines.

Front

How many seismographic stations are needed to locate an earthquake's epicenter?

Back

At least three seismographic stations are required to accurately determine the epicenter of an earthquake.

Front

What is the significance of exposed bedrock ages in geology?

Back

Exposed bedrock ages help geologists understand the geological history and processes that have shaped a region.

Front

What is karst topography?

Back

Karst topography is a landscape formed from the dissolution of soluble rocks, characterized by features such as sinkholes, caves, and underground rivers.

Front

What are P waves and S waves?

Back

P waves (primary waves) are compressional seismic waves that travel fastest through the Earth, while S waves (secondary waves) are shear waves that travel slower and can only move through solids.

Front

What is a mineral's streak?

Back

A mineral's streak is the color of its powder when it is scraped across a streak plate, which can differ from the color of the mineral itself.

Front

What is the role of igneous rock in geothermal activity?

Back

Igneous rock can heat underground water, leading to geothermal features like geysers and hot springs.
