Regents Earth Science 5

Question 1

Which process transports sediment from one location and deposits it in another, forming features like deltas and sandbars?

Accepted Answer

Erosion and deposition

Answer

Erosion picks up and transports sediment via water, wind, or ice, which is then deposited when energy decreases, forming landforms like deltas.

Question 2

What causes the apparent daily motion of the Sun across the sky from east to west?

Accepted Answer

Earth's rotation from west to east

Answer

Earth rotates from west to east on its axis, making the Sun appear to move across the sky from east to west each day.

Question 3

Which mineral is the hardest on the Mohs scale and can scratch all other minerals?

Accepted Answer

Diamond

Answer

Diamond rates 10 on the Mohs hardness scale — the highest — and can scratch every other known natural mineral.

Question 4

A weather station reports dew point temperature equal to air temperature. What does this indicate?

Accepted Answer

Relative humidity of 100%

Answer

When air temperature equals the dew point, the air is saturated (100% relative humidity), and condensation or fog is likely to form.

Question 5

Which type of unconformity occurs when tilted or folded sedimentary layers are eroded and then covered by new horizontal layers?

Accepted Answer

Angular unconformity

Answer

An angular unconformity features older tilted or folded strata below an erosional surface overlain by younger, horizontal sedimentary layers.
