Science Olympiad Earth's Atmosphere
Exam| with Complete Verified Solutions
What is the ozone layer? - ✔forms a thin shield high up in the sky and is located in
the stratosphere. It protects life on Earth from the sun's ultraviolet rays. In the 1980s,
scientists began finding clues that the ozone layer was going away or being depleted.
This allows more UV radiation to reach the Earth's surface. This can cause people to
have a greater chance of getting too much UV radiation. Too much UV can cause bad
health effects like skin cancer, eye damage, and get you sick easier.
What are the layers of the Earth's atmosphere? - ✔The atmosphere is divided into
five layers. It is thickest near the surface and thins out with height until it eventually
merges with space.
Troposphere - ✔is the first layer above the surface and contains half of
Earth's atmosphere. Weather occurs in this layer
Stratosphere - ✔is the second layer of the Earth's atmosphere. Many airplanes fly
in the stratosphere, because it is very stable. Also, the ozone layer absorbs harmful
rays from the Sun.
Mesosphere - ✔is the third layer of the Earth's atmosphere. Meteors or
rock fragments burn up in the mesosphere.
Thermosphere - ✔is the fourth layer of the Earth's atmosphere. It's the layer
with auroras and where the space shuttle orbits
