Water Cycle

Front

In the water cycle, the sun provides

Back

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

Answer explanation

In the water cycle, the sun provides energy for water to evaporate from oceans, lakes, and rivers, which is essential for the process of evaporation to occur.

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, with no definitive start or end point. Therefore, it is accurate to say it has no beginning and no end.

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 steps describe how water moves through 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

Back

hail

Answer explanation

The image depicts hail, characterized by ice pellets falling from the sky. Unlike snow, which is fluffy, or rain, which is liquid, hail consists of solid ice, making it the correct choice.

Front

Why does groundwater usually require less treatment than surface water?

Back

all of the above

Answer explanation

Groundwater typically requires less treatment because it is protected by layers of Earth, which filter out pollutants as water seeps through. Additionally, surface water is more exposed to contaminants from runoff and the atmosphere, making it less clean.

Front

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

Back

Z

Answer explanation

In the water cycle, stage Z represents runoff, where water flows back towards the sea after precipitation. This is the process that collects excess water from land and directs it back to oceans and rivers.

Front

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

Back

Temperature

Answer explanation

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