Earth’s Atmosphere Flashcards
The atmosphere is composed of a mixture of gases
with their unique physical and chemical properties.
TRUE
What is the bulk composition of the Earth’s atmosphere? (99%)
NITROGEN AND OXYGEN!
What is the 0.9% composition of the Earth’s atmosphere?
ARGON
What is the 0.1% composition of the Earth’s atmosphere?
TRACE GASES
Carbon dioxide and ozone, although available in minute amounts, are very essential to life on Earth.
TRUE
What are the layers of the atmosphere? FIVE
TROposphere
Stratosphere
Mesosphere
Thermosphere
Exosphere
TROpa Sina Mama Tatay Ekis
This is the layer closest to Earth.
TROPOSPHERE
This layer has persistently changing weather.
TROPOSPHERE
In the TROPOSPHERE, the temperature gets COOLER as we go HIGHER
TRUE
This is the lowest layer where humans live.
TROPOSPHERE
The troposphere layer REGULATES WEATHER AND CLIMATE. It holds nearly all water vapor in Earth’s atmosphere and is characterized by RELATIVELY ___ ATMOSPHERIC TEMPERATURE which allows high concentrations of oxygen ideal for life.
HIGH
This layer has the OZONE LAYER, which protects the Earth from the sun’s harmful UV protection.
STRATOSPHERE
In the stratosphere, the temperature gets HOTTER/WARMER as we go HIGHER.
TRUE!
Insulating foams, air conditioners, refrigerators, and other things manufactured by industries that use chlorofluorocarbons (CFCs) which causes ozone depletion.
TRUE
As CFCs reach the stratosphere, they will be broken down by the sun’s UV radiation releasing ___. They will react and destroy the ozone.
CHLORINE
Depleted ozone causes LESS UV radiation to reach Earth’s surface
FALSE! MORE
Harmful ozone are found in the MESOSPHERE.
FALSE! TROPOSPHERE. (tropospheric ozone)
This layer is 35 km thick.
STRATOSPHERE
This layer is derived from a greek word that means MIDDLE.
MESOSPHERE.
This oldest layer because it has a minimum temperature of
roughly -85 degrees Celsius.
The reason behind this low temperature is the lessened solar heat and high cooling due to carbon dioxide.
MESOSPHERE
A meteor shower is AKA A SHOOTING STAR.
TRUE
The ____ layer protects the earth from a meteor shower’s debris.
MESOSPHERE
This layer is derived from a greek work which means OUTSIDE.
EXOSPHERE
This 10,000 km thick outermost layer forms a boundary between Earth and space.
EXOSPHERE
The exosphere is the layer that absorbs some _____ and protects the layers underneath.
RADIATION
The exosphere contains ____ and ____. (ELEMENTS)
HYDROGEN AND HELIUM
This is the HOTTEST LAYER.
THERMOSPHERE
The thermosphere layer regulates temperature and ____ X-rays and some ultraviolet radiation emitted by the sun.
FILTERS
The most important layer of the atmosphere is the
boundary layer composed of the troposphere and stratosphere.
TRUE
The energy transferred from Earth’s surface in the form of conduction or even moisture from evapotranspiration stays within this boundary and is not transferred to a higher atmosphere.
TRUE
The stratospheric ozone is BAD.
FALSE! IT IS GOOD
The tropospheric ozone is GOOD.
FALSE! IT IS BAD
The tropospheric harmful ozone when inhaled can irritate
the lungs and breakdown lung tissues.
TRUE
PROVISION
The atmosphere is crucial in enabling and maintaining life on Earth.
TRUE
PROVISION
Without the atmosphere, Earth would look like the?
MOON
PROVISION
Atmospheric gases, such as carbon dioxide and oxygen, are needed by?
ORGANISMS
PROVISION
Carbon dioxide is used by ___ ___ to convert the energy from the sun to usable energy through the process of photosynthesis.
PHOTOSYNTHETIC ORGANISMS
PROVISION
Oxygen is used by ___ for cellular respiration.
HUMANS
PROTECTION
This layer in the stratosphere is necessary in enabling life on Earth.
OZONE LAYER
PROTECTION
This layer in the stratosphere is necessary in enabling life on Earth. If it does not exist, harmful rays from the sun would reach the surface of Earth and prevent most organisms from surviving.
OZONE LAYER
Water is a renewable resource because it is continually circulated across Earth through a process known as the?
HYDROLOGIC CYCLE
What are the three important processes in the hydrologic cycle?
EVAPORATION
CONDENSATION
PRECIPITATION
HC
What is evaporation? explain. AWP
Evaporation is the process of converting liquid to gas.
Water from the oceans, lakes, streams, rivers, and other
bodies of water undergo this process, and it becomes atmospheric water vapor.
HC
What is condensation? explain. C
Cloud formation that happens by converting water vapor to liquid form.
HC
The water vapor in the atmosphere is stored in the form of clouds and moisture (humidity).
TRUE
HC
What is precipitation?
The process of RELEASING water from
the clouds in the form of rain, snow, sleet, or hail.
HC
It is the process of returning water from the atmosphere back to the Earth’s surface.
PRECIPITATION
The atmosphere is a crucial part of the water cycle as it serves as the reservoir of large amounts of water.
TRUE
The ______ cycle describes the
movement of water from one area to another by changing states―liquid to vapor to ice and back again. IT IS A NEVER ENDING CYCLE.
WATER CYCLE/HYDROLIC CYCLE
The atmosphere is an efficient medium to move water around the globe.
TRUE
