A place that doesn't get much rain over many years does not necessarily have a cold climate. The amount of rainfall a place receives does not directly determine its temperature. Other factors, such as latitude, elevation, and ocean currents, play a significant role in determining the climate of a place. Therefore, it is incorrect to assume that a lack of rain automatically means a cold climate.
19.
Stratus clouds form _______________
Correct Answer
B. Layers of even sheets clouds
Explanation
Stratus clouds form when warm air rises and cools, causing water vapor to condense into a flat, uniform layer of clouds. These clouds typically cover large areas of the sky and have a smooth, sheet-like appearance. Unlike puffy white clouds, which are cumulus clouds, or fibrous or curly clouds, which are cirrus clouds, stratus clouds are characterized by their even and consistent structure. Fog, on the other hand, is a ground-level cloud that forms when the air near the surface cools and reaches its dew point.
20.
Cumulus cloud are associated with ________________
Correct Answer
A. Fair weather and rainstorms
Explanation
Cumulus clouds are associated with fair weather and rainstorms because they are large, white, and fluffy clouds that typically form on sunny days with stable atmospheric conditions. However, as they continue to grow vertically, they can develop into cumulonimbus clouds, which are associated with thunderstorms and heavy rainfall. Therefore, cumulus clouds can indicate both fair weather and the possibility of rainstorms depending on their development and atmospheric conditions.
21.
The process by which water returns to the earth's surface in the form of rain, snow, etc.
Correct Answer
B. Precipiation
Explanation
Precipitation is the correct answer because it refers to the process by which water returns to the earth's surface in the form of rain, snow, etc. This process occurs when water vapor in the atmosphere condenses into liquid or solid form and falls back to the ground. Evaporation, on the other hand, is the process by which water changes from a liquid to a gas and rises into the atmosphere. Therefore, precipitation is the most appropriate term to describe the given process.
22.
An anemometer measures_______________.
