Planet Earth
CHAPTER 1

Earth is the third planet from the sun. The Earth is filled with tons of living
organisms. Organisms are living things.
1.1 PLANET OF LIFE
![Page 3: Planet Earth. Earth is the third planet from the sun. The Earth is filled with tons of living organisms. Organisms are living things. 1.1 PLANET OF LIFE](https://reader035.vdocuments.net/reader035/viewer/2022062408/56649e905503460f94b94866/html5/thumbnails/3.jpg)
There are three places where
organisms can be found. The
lithosphere, the hydrosphere, and the atmosphere are the places where they
can be found.

One of the reasons organisms can live on
earth is that earth has liquid water.
Liquid water helps with many thing like
heating the earth.

The Lithosphere: a layer of rock that
covers the earth from 10 to 200 kilometers deep. There are three
types of rock that make this up.
1.2 EARTH’S LAND AND WATER
![Page 6: Planet Earth. Earth is the third planet from the sun. The Earth is filled with tons of living organisms. Organisms are living things. 1.1 PLANET OF LIFE](https://reader035.vdocuments.net/reader035/viewer/2022062408/56649e905503460f94b94866/html5/thumbnails/6.jpg)
One type is the igneous rock. This is
formed when liquefied rock is
cooled and becomes solid.

Another rock is the sedimentary rock.
This rock is formed by the weathering of other rocks and then those sediments get
compressed and cemented into rock.

The last type of rock is the metamorphic rock. This rock is
formed with lots of heat and pressure.

The hydrosphere: the part of earth
where all the water based animals live.

70% of the world is covered in water.
97% of that water is salt water. The salt water contains 35 grams of salt in a
liter. The other 3% of the water is fresh
water.

Two-thirds of the fresh water exists in frozen glaciers and
ice caps and because there is little fresh
water, it is a valuable substance.

Not all water is above ground. A lot
of water is found underground. There
are two types of underground water.
Aquifer: underground places filled with water and
Artesian wells: water flows to the
surface due to high pressure
underground.

The Atmosphere: an envelope of gases that surrounds earth and also holds the air
we breath.
1.3 THE ATMOSPHERE
![Page 14: Planet Earth. Earth is the third planet from the sun. The Earth is filled with tons of living organisms. Organisms are living things. 1.1 PLANET OF LIFE](https://reader035.vdocuments.net/reader035/viewer/2022062408/56649e905503460f94b94866/html5/thumbnails/14.jpg)
There are four different layers of the atmosphere. There is the troposphere, the
stratosphere, the mesosphere, and the
thermosphere.
1.3 PAGE 2
![Page 15: Planet Earth. Earth is the third planet from the sun. The Earth is filled with tons of living organisms. Organisms are living things. 1.1 PLANET OF LIFE](https://reader035.vdocuments.net/reader035/viewer/2022062408/56649e905503460f94b94866/html5/thumbnails/15.jpg)
The lowest part is the
troposphere and the next it the stratosphere. The troposphere: the layer that holds most of the
weather and touches the earth. The
stratosphere: reaches the height of 50 km above earth and also contains a gas called
ozone.

1.3 PAGE 4
The next two layers are the mesosphere
and the thermosphere. The
mesosphere: it extended up to 85 km above earths surface. The thermosphere: the outmost layer of
the atmosphere and it can get up to 2000
degrease C.

The biosphere: all the parts of the earth
that support and contains life.
