Abeka Grade 5 Science Chapter 8 Quiz 22

Which 3 are ingredients of clouds?

• Water

• Rising air

• Dust

• Heat

Identify the types of clouds.

1. ​ (a)   : Puffy and bulgy clouds that come in many different sizes; Often seen in the sky on a fine day

2. ​ (b)   : Flat, gray clouds that are low blankets; Often a sign that rain is approaching

3. ​ (c)   : Light, delicate, feathery looking clouds whose name means "wisp" or "curl."; Scattered remains of much larger clouds

4. ​ (d)   : A special type of cloud at ground level

• Cumulus

• Stratus

• Cirrus

• Fog

What are the three types of combination clouds?

• Nimbostratus

• Cirrostratus

• Stratocumulus

• Cirrocumulus

Answer explanation

The three combination clouds:

Cirrostratus: Very high clouds made of thin sheets of ice crystals. Has characteristics of both cirrus and stratus clouds.

Cirrocumulus: Puffy, heap clouds made of ice crystals; So high in the air that from the ground they appear as tiny white specks in the sky

Stratocumulus: Low, thick blanket covering clouds that look bumpy and rolling in appearance

The two chief rain-producing clouds are the ______ and the ______.

• Cumulonimbus

• Nimbostratus

• Altocumulus

• Altostratus

Answer explanation

Altocumulus: Medium-height clouds in the cumulus family that look smaller than regular cumulus clouds.

Altostratus: Higher-flying relatives of ordinary stratus clouds

​ (a)   : Forms on cool, clear nights, especially during the long nights of autumn

​ (b)   : Forms when warm air moves over cold water

​ (c)   : Forms when water vapor condenses in cool air immediately after evaporating; Also known as Evaporation fog

• Radiation fog
• Sea fog
• Steam fog

Whether it takes the form of rain, snow, or ice, water that falls from clouds is called ______.

• precipitation

• transpiration

• condensation

• evaporation

Match each type of precipitation with its correct description.

• Wet Snow

• Ice crystals that melt and fall to Earth as a drop of liquid water

• Sleet

• Ice crystals that travel singly to the Earth

• Dry Snow

• Ice crystals that melt and refreeze into tiny pieces of ice in the air

• Rain

• Ice crystals that form in thunderheads into pieces of ice that are tossed around in the cloud until they're too heavy

• Hail

• Ice crystals that melt only slightly and stick together

Answer explanation

A thunderhead is a thunderstorm is produced by the cumulonimbus cloud.

______ are ice crystals that fall through warm air and then melt, turning into raindrops. The raindrops then freeze as soon as they strike the frozen ground.

• Sleet

• Freezing Rain

• Snow

• Hail

______ may be the only type of precipitation that doesn't begin as an ice crystal.

• Hail
• Freezing Rain

• Tropical Rain

• Dry Snow

🌦 A fully developed cumulonimbus cloud is fueled by ​ (a)   of warm air rising from the ground into the cloud.

🌦 Strong air currents rush toward the ground. Raindrops falling through the cloud draw powerful ​ (b)   along with them.

• updrafts
• downdrafts
