In the water cycle, the sun provides

Back

energy for water to evaporate from oceans, lakes and rivers.

Answer explanation

The sun provides energy that heats water in oceans, lakes, and rivers, causing it to evaporate. This process is essential for the water cycle, making "energy for water to evaporate from oceans, lakes and rivers" the correct choice.

Front

The water cycle has

Back

no beginning and no end.

Answer explanation

The water cycle is a continuous process of evaporation, condensation, and precipitation. It has no definitive starting or ending point, making 'no beginning and no end' the correct choice.

Front

How many main steps does the water cycle have?

Back

4

Answer explanation

The water cycle consists of 4 main steps: evaporation, condensation, precipitation, and collection. These processes continuously recycle water in the environment, making 4 the correct answer.

Front

During which stage do clouds form?

Back

condensation

Answer explanation

Clouds form during the condensation stage when water vapor cools and changes back into liquid droplets, creating clouds. This process is essential in the water cycle, distinguishing it from evaporation and precipitation.

Front

What is it called when plants give off water vapor as a waste product?

Back

transpiration

Answer explanation

The process by which plants release water vapor as a waste product is called transpiration. This is essential for regulating water and nutrient flow within the plant.

Front

This is a picture of: snow, rain, fog, hail

Back

hail

Answer explanation

The image depicts hail, which consists of ice pellets that form in thunderstorms. Unlike snow, rain, or fog, hail is characterized by its solid, icy nature, making it the correct choice.

Front

Why does groundwater usually require less treatment than surface water?

Back

All of the above: The layers of Earth protect groundwater from pollutants, as groundwater sinks into the ground, the layers of rock act like a natural filter and remove pollutants from the water, and surface water has more exposure to pollutants in runoff and the atmosphere.

Answer explanation

Groundwater typically requires less treatment because the Earth's layers protect it from pollutants, and as it filters through rock, many contaminants are removed. In contrast, surface water is more exposed to pollutants from runoff and the atmosphere.

Front

During which stage does water flow back towards the sea as runoff?

Back

Z

Answer explanation

In the water cycle, runoff occurs when water flows over the ground and returns to bodies of water like the sea. This process is represented by stage Z, where water collects and moves back towards the sea.

Front

Which factor is responsible for there being different forms of precipitation?

• Evaporation
• Run-off
• Temperature
• Transpiration

Back

Temperature

Answer explanation

Different forms of precipitation, like rain and snow, are primarily influenced by temperature. Warmer temperatures lead to rain, while colder temperatures result in snow, making temperature the key factor in determining precipitation type.

Front

Snow, sleet, hail, and rain are all examples of ________________.

Back

precipitation

Answer explanation

Snow, sleet, hail, and rain are all forms of water that fall from the atmosphere to the ground. This process is known as precipitation, which encompasses all types of moisture that reach the Earth's surface.
