Unique Earth

LA TIERRA

THE UNIQUE PROPERTIES OF THIS

PLACE WE CALL HOME.

PLANET
EARTH

1. LOCATION

UNLIKE THE OTHER PLANETS, EARTH IS
NOT TOO CLOSE TO THE SUN AND NOT
TOO FAR AWAY FROM THE SUN SO IT
IS NOT TOO HOT AND NOT TOO COLD
FOR WATER TO EXIST IN ALL 3 STATES

AND FOR LIFE TO EXIST.

2. SIZE

EARTH IS THE RIGHT SIZE TO HAVE

AN ATMOSPHERE AND ENOUGH

GRAVITATIONAL PULL TO KEEP OUR

ATMOSPHERE, WATER, AND

EVERYTHING ELSE ON THE SURFACE

OF THE PLANET.

3. PLATE TECTONICS

THE PLATES OF THE EARTH ARE

MOVING, AND THIS IS IMPORTANT

BECAUSE THAT IS THE PROCESS

THAT CREATES LAND. NOT

EVERYTHING IS UNDER WATER.

4. JUPITER

JUPITER IS LIKE A BIG BROTHER OR

SISTER, PROVIDING PROTECTION FOR

OUR PLANET FROM AFAR. BECAUSE

JUPITER IS

SO LARGE, IT DEFLECTS COMETS AND
ASTEROIDS FROM HEADING OUR WAY.
It can also send things in our direction - oops

5. OUR MOON

OUR MOON KEEPS US LOCKED IN A

23.5 DEGREE TILT SO IT KEEPS EARTH
FROM WOBBLING ON OUR AXIS WHICH
KEEPS US FROM EXPERIENCING HUGE

FLUCTUATIONS IN WEATHER.

HOW EARTH

PROVIDES AIR FOR

US TO BREATHE

6. Earth's atmosphere is 78% nitrogen,
21% oxygen, and less than 1% argon,
carbon dioxide and other trace gases.
This atmosphere is held to the surface of the planet by gravity.

7. Because Earth has a magnetosphere,

the atmosphere is protected from

solar winds that threaten to blow it off

the surface.

What is a magnetosphere?

HOW EARTH

PROVIDES FOOD
FOR US TO EAT

8.Because Earth is a terrestrial planet, which

means that the surface of the planet is

rocky and solid.

Plants grow in the soil, taking in minerals

and water through their root system to live.

Sunlight, combined with water, and carbon

dioxide are used by plants to perform

photosynthesis, a process by which plants

turn these things into glucose/sugar for

them to grow.

HOW EARTH

PROVIDES WATER
FOR US TO DRINK

While we do not know how water got to

Earth or why we have so much of it, we do

know that life

could not exist here without it.

9.Water exists in all 3 states naturally on
Earth because the heat Earth receives is

redistributed around the globe from

warmer to cooler areas, making Earth a
moderate temperature for water to exist.

While Earth is covered in 71% water, only

1% is available to drink as fresh water.

Water is continuously recycled through the
Earth System through a process called The

Water Cycle

HOW EARTH PROVIDES

PROTECTION FROM
HARMFUL UV RAYS

10.The stratosphere, contains the ozone layer
in Earth’s atmosphere which protects me

from harmful UV rays that cause skin

cancer

HOW EARTH PROVIDES

PROTECTION FROM
AND BEING STRUCK

BY METEORITES

11.The Mesosphere layer in Earth’s

atmosphere protects the surface of Earth

from being struck by large meteors because

they burn up here due to the friction

created when they enter this part of our

atmosphere.
