2.Reading: Read the text below and answer the questions that follow.
Water on Earth can be found in three different forms, or states. These states
Precipitation will take on different forms. The form depends on the conditions that exist inside the clouds and the condition of the air the water travels through on its way to the ground. Drops of liquid water fall as rain, the most common form of precipitation. If the drops of water fall through air that is warmer than water’s freezing point, they will remain as rain. Sometimes cold temperatures inside clouds produce ice crystals that melt in warmer air on their way down, ending up as rain as well.
If raindrops fall through air that is below the freezing point of water, they form tiny frozen drops known as sleet. If the air inside the cloud and the air on the way down are both below the freezing point, ice crystals will form and fall as snowflakes. There is a lot of variation in snow, depending on how cold it is when it falls. Warmer temperatures mean “wetter” snow, while colder temperatures mean drier, fluffier snow.
Perhaps the most interesting form of precipitation is hail. Hail forms when windy conditions combine with freezing temperatures. Drops of frozen rain begin to fall, and are then repeatedly caught up by the wind and pushed back up through the clouds where they gather more and more layers of ice. When they become too heavy for the wind to lift, they fall to the ground as hail.
No matter what form the precipitation takes, much of it will become runoff and find its way back to the sea. Most of the rest will join surface water in lakes and streams or soak into the ground and become groundwater. Some will spend some time atop tall mountains as ice and snow.
All water awaits its turn to participate once again in each state of the water cycle. It continually changes from one state to another, thus the cycle never ends.
Answer the following questions based on the reading passage.
1) What are the three stages of the water cycle?
2)Why does precipitation take different forms?
3) Describe the conditions that are necessary for snow to fall.
4) What conditions are necessary to form hail?
5) How does precipitation return to the water cycle?
6)Write a summary of the article including the following verbs:
