Activity 5. Listen to the following recording and complete the following
text
Water can change from one state to another:
- Solidification: When liquid water gets very cold, it freezes and becomes
a solid: ice, snow or hail.
- Melting: when ice or snow warms up, it melts and becomes liquid water.
This change is called fusion.
- Evaporation: when liquid water gets hot, it becomes steam or water vapour.
- Condensation: when water vapour gets cold, it becomes liquid water.

Hydrosphere True or false
-The hydrosphere is all the water on the Earth -There are two types of water: saltwater and fresh water
-Seawater doesn’t contain salt
-Fresh water contains a lot of salt
-Almost all the saltwater is found in lakes, rivers and groundwater
-About 97% of our planet’s water is in seas and
oceans
-About 2% of our planet’s water is in our
aquifers, lakes and rivers
-About 2% of our planet’s water is frozen
-Snow, ice, icebergs, glaciers have fresh water
-Some fresh water is found in the atmosphere
as gas
- Rivers, lakes and groundwater have fresh water
- Oceans and seas have saltwater

Activity 9. Listen and complete the text
Student A
The hydrosphere is all the water on the Earth. There are two types of water: saltwater and fresh water. Seawater contains a large amount of salt. The water on land
only contains very small amounts of salt, so we call it fresh water.
Almost all the saltwater is found in oceans and seas. About 97% of our planet’s water
is in our oceans and seas.
Student B
A small amount of fresh water is found in solid form as snow and ice in the polar regions, icebergs, glaciers and on mountains. About 2% of our planet’s water is frozen.
A much smaller amount of fresh water is found on land in liquid form as rivers, lakes
and groundwater. About 1% of our planet’s water is in our aquifers, lakes and rivers.
Some fresh water is also found in the atmosphere as water vapour, as a gas.

Activity 12. Listen to the following sentences and say if they are true or
false. Then, work in pairs and check your answers with your classmates
The Water Cycle
1. The water cycle is the constant circulation of True
water between the sea, the atmosphere and the land.
2. This process has five basic phases. False
3. The Sun heats the solid water in oceans, rivers and lakes.
False
4. The water evaporates and changes its state: True
from liquid water to water vapour.
5. Water vapour rises and condenses. True
6. Condensation changes liquid water into water drops.
False
7. These water drops form clouds.
True
8. Water falls from clouds in solid form as rain or in False
liquid form as snow or hail.
9. Water flows over the land and is used by plants True
or becomes underground water.
True
10. Some water fills rivers, lakes, seas and oceans.
11. When water from oceans, rivers and lakes evaporates,
False
the cycle finishes.
Activity 15. Match the two halves of the sentences. Then, put your sentences
with your classmate’s sentences and complete the text that explains the
water cycle

STUDENT B
This process: has four basic phases.
The water evaporates and changes
its state:
from liquid water to water vapour.
These water drops form clouds.
Water falls from clouds in liquid
as rain or in solid form as snow or form hail.
Some water fills rivers, lakes, ponds, seas, oceans...
When water from oceans, rivers and evaporates, the cycle begins again.

We use water:
1. For personal hygiene
2. For washing and cleaning
3. For watering fields of crops
4. For watering plants
5. For cooking
6. For animals
7. For doing water sports
8. For making electricity in the hydroelectric centres
9. For drinking
