Science 8 Test 8

Which of the following is a high-level cloud?

• stratocumulus

• altostratus

• cirrostratus

• nimbostratus

What is the process in which rain forms from melted snowflakes?

• sublimation-deposition process

• Bergeron-Findeisen process

• collision-coalescence process

• Hadley-Ferrel process

What are billowy, low-level clouds with flat bases?

• cumulonimbus

• cumulus

• stratus

• altostratus

How does rain usually form in tropical areas?

• Seawater evaporates and then condenses high in the atmosphere.

• Cloud droplets blown upward by updrafts freeze and remelt.

• Snowflakes form high in a cloud and melt on the way down.

• Unusually large cloud droplets stick together and grow larger.

Which of the following is one of the three major factors that cause weather?

• uneven heat distribution

• ocean currents

• human activity

• volcanic eruptions

From what does a frontal cyclone draw its energy?

• warm front

• warm air mass

• cold air mass

• cold front

What type of air mass is cold and dry?

• maritime polar

• continental polar

• continental tropical

• maritime tropical

What type of air mass forms over the Caribbean Sea?

• maritime polar

• continental polar

• continental tropical

• maritime tropical

Why are condensation nuclei needed for clouds to form?

• Condensation nuclei cool the air enough for water vapor to form.

• Clouds usually only form when small particles are present in the air.

• Water vapor usually requires a surface to turn into liquid water.

• Condensation nuclei increase the rate of adiabatic cooling.

With what type of front does a frontal cyclone usually begin?

• cold front

• occluded front

• stationary front

• warm front
