Layers of the Atmosphere
the measure of the force with which air molecules push on a surface is called
air pressure
narrow belts of high speed winds that blow from east to west between 7km and 16km above earth's surface are called
jet streams
tiny particles of a solid that are suspended in air or water are
particulates
name an example of thermal expansion
marshmallow in microwave, thermometer, balloon or basketball in garage
name the three gases in earth's atmosphere
nitrogen, oxygen, and carbon dioxide/other gases
How does the ozone layer affect us?
Protects us from UV rays
why is their wind at the beach during the day and not at night?
land breeze
the land warms faster, causing the warm air to rise and the cold air from the ocean comes over beneath the warm air
who is responsible for monitoring the aqi or air quality index?
epa, environmental protection agency
How is heat transferred from one object to another? ex. high temp to low temp, cold to hot
high temp to low temp, hot to cold
what do cfc's or chlorofluorcarbants do to the atmosphere?
they break down the ozone layer
name the layer: I am warm, air pressure rises in my layer, and I am the layer above the troposphere
stratosphere
2 global winds that blow storms from the west to the east across the usa
westerlies and jet streams
name some natural sources of air pollution
volcanic eruptions, wildfires, or dust storms
the average kinetic energy of an object
temperature
if global temperatures continue to rise, what could happen?
changes in rainfall patterns, rising sea level, severe storms, drought, agriculture problems
name the layer: I am very cold, but am supposed to be hot, I am the fourth layer from Earth's surface, and satellites orbit in my layer
thermosphere
what degrees are the horse latitude located
30 degrees
name two long term effects and short term effects of air pollution
short term: coughing, headaches, difficulty breathing, itchy or burning eyes
long term: asthma, emphysema, allergies, lung cancer, chronic bronchitis
the total kinetic energy of an object
thermal energy
what causes wind
the difference in air pressure, because the sun heats the earth unevenly
the greenhouse effect is when gases in the atmosphere trap heat, causing it to be warmer. how does the greenhouse effect support life on earth?
it maintains a suitable temperature for us, so that way we can grow and live
where do the three types of global winds start and end? (in degrees) ex. trade winds: 65 degrees and 90 degrees
trade winds: 0 degrees to 30 degrees
westerlies: 30 degrees to 60 degrees
polar easterlies: 60 degrees to 90 degrees
name some indoor air pollutants
chlorine, ammonia, formaldehyde, chemica;s from glue, and radon
an image shows a person holding a pot over a fire. 1 what do the arrows pointing out of the fire mean? 2 what do the arrows in the pot, circling around each other mean? 3 what does the arrow from the handle to the hand mean?
1 radiation
2 convection
3 conduction
a gas produced when sunlight reacts with vehicle exhaust and oxygen
ground level ozone
