Precipitation And The Water Cycle Quiz

Explanation
Condensation involves the process of water vapor turning into liquid water. This typically occurs when warm air rises and cools down, causing the water vapor to condense and form tiny droplets. Clouds are formed through condensation, as the water vapor in the air condenses around tiny particles such as dust or ice crystals. Therefore, clouds are the correct answer as they are directly involved in the process of condensation.

Explanation
Precipitation occurs over land because it is the process by which water vapor in the atmosphere condenses and falls to the ground as rain, snow, sleet, or hail. This process is driven by various factors such as temperature, humidity, and air currents. When the conditions are right, the water vapor condenses into liquid or solid form and falls back to the Earth's surface over land areas. Precipitation is an essential part of the Earth's water cycle and plays a crucial role in replenishing freshwater resources.

Explanation
Transpiration is the process by which water is lost from the leaves of plants through small openings called stomata. Sand does not have stomata or any mechanism to facilitate transpiration, so it does not contribute to transpiration. Therefore, the statement that transpiration comes from sand is false.

Explanation
Evaporation can occur in urban centers. Evaporation is the process by which a liquid, such as water, changes into a gas or vapor. Urban centers have various sources of water, such as lakes, rivers, and even man-made water bodies like fountains and pools. These water sources can provide the necessary conditions for evaporation to take place, such as sunlight and heat. Additionally, urban centers also have paved surfaces, buildings, and vehicles that can contribute to the heating of the environment, further promoting evaporation. Therefore, it is possible for evaporation to occur in urban centers.

Explanation
Evaporation is the process by which a liquid, such as water, changes into a gas, usually due to heat. Lakes, soil, and dams can all undergo evaporation as they contain water that can be heated and turned into vapor. However, animals do not correspond with evaporation as they are living organisms and do not undergo the same physical process of turning into gas.
