Atmosphere Basics
This invisible layer of gases surround the Earth.
What is the atmosphere?
This is the lowest layer of the atmosphere where weather occurs.
What is the troposphere?
Air moves from areas of high pressure to areas of this.
What is low pressure?
This is the main source of energy for Earth.
What is the sun?
This celestial body obits Earth.
What is the moon?
The 2 main gases in the atmosphere are nitrogen (N) (78%) and this gas (and %).
What is Oxygen (O) at (21%)?
Air pressure is caused by this force acting on air particles.
What is gravity?
A large body of air with similar temperature & humidity is called this.
What is an air mass?
Energy from the Sun that reaches Earth is called this.
What is solar radiation?
This rise & fall of ocean water levels are called this.
What are tides?
These are two of the three main reasons the atmosphere is organized into layers that are essential for life on our planet.
What are acts as a screen blocking out harmful ray from the sun / ensure a relatively stable climate / includes oxygen (O) for Cellular Respiration and carbon dioxide (CO2) for photosynthesis?
A altitude increases, air pressure generally does this.
What is decreases?
This type of front forms when cold air pushes under the warm air.
What is a cold front?
This process traps heat in the atmosphere using gases like CO2.
What is the greenhouse effect?
What are visible light, infrared, and ultraviolet rays?
This gas helps trap heat in the atmosphere & contributes to the greenhouse effect.
What is carbon dioxide (CO2)?
This layer contains the ozone layer & absorbs UV radiation.
What is the stratosphere?
These are high-pressure systems that usually bring clear skies.
What are anticyclones?
This renewable energy source uses sunlight to produce electricty.
What is solar energy?
When the sun, moon and Earth are aligned, stronger tides occur called this.
What are spring tides?
This layer of gas protects the Earth from harmful ultraviolet radiation.
What is the ozone layer?
Name all 5 layers of the atmosphere.
What are the troposphere, stratosphere, mesosphere, thermosphere & exosphere?
Global air movement caused by uneven heating of Earth is called this.
What is atmospheric circulation?
Name one way energy can be obtained from the atmosphere.
What is wind energy? or What is solar energy?
This type of energy is generated using the movement of ocean tides.
What is tidal energy?
