atmosphere and hydrosphere
TRANSCRIPT
It’s important to all living organisms because:
1. It contains the gases we need to survive
2. It protects us from the harmful rays of the Sun
3. It helps maintain the temperature of the Earth by
stopping the Earth from heating up or cooling down
too quickly.
4. It transports water around the planet in the form of
clouds
Pollution changes the atmosphere and makes it dirty.
Pollution destroys the environment.
Dust and smoke from cars, and industry pollute the planet.
WE MUST PROTECT THE ATMOSPHERE AND KEEP IT CLEAN !!
The weather is all the natural changes and events
that happen constantly in the atmosphere
WIND: The movement of the air; breeze / gale
CLOUDS: a collection of tiny droplets of water.
PRECIPITATION: in the form of snow, rain or hail.
OTHER PHENOMENA: lightning, rainbows, heat waves, cold
fronts, hurricanes ...
1. We can choose suitable clothing
2. We can protect people, crops and animals from bad
weather
3. We can avoid risks in transport
4. We can evacuate people to avoid catastrophes
caused by hurricanes and floods.
Weather forecasters make predictions about the
weather.
The Hydrosphere is all the water on Earth.
LIQUID WATER: Can be Fresh Water or Salt Water.
ICE: When liquid water freezes and becomes solid.
WATER VAPOUR: When water is heated and evaporates.
TYPES OF WATER IN THE
HYDROSPHERE:
1. SURFACE WATER: found on the
surface of the geosphere: oceans,
seas, rivers, streams, lakes and
ponds.
2. GROUNDWATER: formed when
surface water filters inside the
geosphere.
1. It helps maintain the Earth’s temperature
2. It provides the habitat to aquatic organisms
3. Plants need it to make food during photosynthesis
4. Animals need it to survive
5. Human beings use it for Industry, hygiene and recreation.
POLLUTION can also damage the hydrosphere and harm the living organisms that live in it.
There is always the same amount of water on Earth, it’s moving around in
the form of ...
RIVERS: Circulate over the surface of the Earth until they flow into the
sea.
CLOUDS: move around the atmosphere, produce precipitation and
disappear.
SNOW - ICE: formed during the winter, and melt in summer.
RAINWATER: filters underground and appears again in natural springs.
