Atmosphere and ocean

Ocean stratification

Dark zone

Most deep creatures use bioluminescence to produce lights

Sunlight cannot penetrate at all

It is completely dark

Twilight surface

Becomes the habitat for large marine animals, such as giant squids and various species of whales

The fishes living in this zone have large eyes to enable them to see better

It receives a small amount of sunlight

Surface ocean

most aquatic plants live in this zone

It receives the most amount of sunlight

Atmospheric stratification

Troposphere layer

It has the highest air pressure

Formation of cloud and weather changes such as rain,snow and lightning occur in this layer and therefor the weather may be turbulent

Closest to the Earth

Stratosphere layer

The rays can cause skin cancer,eye cataract and weaken the immune system of our body

It has the ozone layer to protect the Earth from ultraviolent rays from the Sun

It allows aircrafts to fly safely

The air is calm and thin ,has no clouds,dust nor water vapour

Mesosphere layer

Meteoroids rub against air particles and burn up into fragments in the mesosphere to produce meteors

Protects the Earth from meteoroids

The coldest layer

Thermosphere layer

the gas atoms inthe ionosphere are blasted by ultraviolent reflects radio signals back to the Earth to enable radio communication between people

Contains the ionosphere layer.

the hottest layer

Exosphere layer

Man-made satellites,space telescopes and space shuttles orbit the Earth

Air becomes thinner towards space

Contains light gases such as helium and hydrogen

The outermost layer
