BMST - Basic Math and Science Earth's Geological Cycles Questions and Answers 5

Question 1

What is the approximate age of Earth based on radiometric dating?

Accepted Answer

4.5 billion years

Answer

Radiometric dating of meteorites and the oldest Earth rocks places Earth's age at approximately 4.5 billion years.

Question 2

Which process in the rock cycle occurs when sediments are compressed and cemented together over time?

Accepted Answer

Lithification

Answer

Lithification is the process by which loose sediments are compacted under pressure and cemented by minerals to form sedimentary rock.

Question 3

At a convergent boundary where two continental plates collide, what geological feature typically forms?

Accepted Answer

Mountain range

Answer

When two continental plates collide at a convergent boundary, neither subducts easily, so the crust crumples and folds upward to form mountain ranges like the Himalayas.

Question 4

What is the primary source of energy that drives the water cycle on Earth?

Accepted Answer

Solar energy from the Sun

Answer

The Sun's energy drives the water cycle by heating water in oceans, lakes, and rivers, causing evaporation that lifts water vapor into the atmosphere.

Question 5

Which type of seismic wave travels only along Earth's surface and causes the most damage during an earthquake?

Accepted Answer

Surface waves

Answer

Surface waves travel along Earth's surface and produce the rolling or shaking motion that causes the most structural damage during earthquakes.
