100
Satellites orbit here. Charges particles collide here making aurora borealis
Thermosphere
100
Which layer contains the ozone?
Stratosphere
100
What would happen to the air pressure if density decreased?
Air pressure would decrease
100
What contains the umbra inside it?
Preumbra - outer region of the shadow. Light nay be partially blocked
100
Why would a hiker need oxygen support when he/she reaches the top of a very tall mountain?
It is more difficult to breathe near the top of the mountain because the oxygen particles are very spread apart. The air particles are less dense, so it is harder to grab the oxygen through mouth and nose
200
What is the mesosphere?
Temperature decreases with height throughout the mesosphere.
The coldest temperatures in Earth's atmosphere,
(-130° F), are found near the top of this layer.
200
What is the upper part of the atmosphere?
exosphere
200
How does the diagram on the right help explain the method of separating oil and water?
The syringe can lift the oil apart from the water because the oil is less dense and it floats to the top
200
This is when the moon passes through the shadow of the earth. These are safer to human viewing
Lunar eclipse
200
Define the following: Melting, Freezing, Vaporization, Condensation, Heat Energy
Melting - process of solid to liquid
Freezing - process of liquid to solid
Vaporization - process of liquid to gas
Condensation - process of gas to liquid
Heat energy - the energy that moves from one place to another due to a change in temperature
300
What are the three requirements for an eclipse?
Straight line sun- earth- moon
Moving object as from revolution of objects
Light source sun
300
How does the diagram on the right help explain the method of separating salt from water?
Allow the water to evaporate and leave the salt particles
300
A mixture that contains equal distribution, all particles are evenly spread out
Homogeneous mixture
300
This is when the Earth passes through the shadow of the moon
Solar eclipse
300
What is the connection between temperature and heat energy?
As one increases, the other increases
400
4 main layers of the atmosphere starting above Earth
Earth, Troposphere, Stratosphere, Mesosphere, Thermosphere
400
What is the relationship between altitude and air pressure?
They are opposites. As altitude increases (going up a mountain), air pressure deceases (and density decreases).
400
A mixture is a mixture in which the composition is not uniform throughout the mixture.
Heterogeneous mixture
400
why there is snow at the top of the mountain and not at the bottom?
Snow at top. Lower air pressure brings unpleasant weather
400
The material that dissolves is called the
solute
500
Which layer of the atmosphere is where weather occurs?
troposphere
500
What would happen to air pressure if you increased altitude?
air pressure would decrease (less air sitting on top of your head at the top of the mountain)
500
What is the umbra?
Inner region of a shadow
Light totally blocked
500
How does air pressure change with increasing altitude?
Air pressure decreases as altitude increases. Notice the particle arrangement
500
What is the universal solvent?
water
