Earth Sun Relationship
Round and Round
Our Atmosphere & Life on Earth
100
A measure of the average KINETIC ENERGY of the individual atoms or molecules in a substance is this.
What is temperature?
100
Both life and weather are in this layer of Earth’s atmosphere.
What is the troposphere?
100
This is the name of the wobble in the Earth’s rotation.
What is precession?
100
The longest day of the year occurs on this special day. (2X for month in which it occurs.)
What is the summer solstice? What is June?
100
We are protected from gamma radiation and x-rays by this part of our atmosphere. (2X for its location as well)
What is the thermosphere? What is the top layer of the atmosphere?
200
This is the transfer of heat through matter by direct contact which then results in molecular activity.
What is conduction?
200
This top layer of Earth’s atmosphere is characterized by increasing temperatures due to this. (2X for answer plus the layer name)
What is the Thermosphere? What is oxygen’s absorption of x-rays and gamma radiation?
200
The seasons of the Earth are caused by this.
What is the Earth’s tilt?
200
On the winter solstice ancient people were afraid that the sun was disappearing because of this. (2X for major celebration around this solstice)
What is that the days grew shorter & shorter/the nights grew longer? What is Christmas/Hanukkah/Kwanza?
200
The formation of this layer of molecules in our atmosphere made life on land possible.
What is the ozone layer?
300
The transfer of heat by mass movement or circulation within a substance. (2X for 2 examples)
What is convection? What is boiling water/convection cell in air, ocean, mantle of Earth…?
300
This layer of the Earth’s atmosphere contains the ozone layer. (2X for the number of oxygen atoms)
What is the stratosphere? What is O3?
300
The equinoxes occur in these two months, and begin these two seasons. (2X for both)
What are March & September, and Spring & Fall?
300
What do the autumnal and vernal equinoxes have in common?
What is that day and night are equal in length?
300
Why could we say that carbon dioxide, methane, and water vapor have Jekyll-Hyde effect on our atmosphere? (3X credit for complete answer, including "that other planet" which has an exaggerated version of this.)
What is that we need the greenhouse effect but a runaway greenhouse effect would kill us? AND Venus has a runaway greenhouse effect.
400
This is what we call the transfer of energy (heat) through space by electromagnetic waves.
What is radiation?
400
The temperature drops in this layer, which separates the stratosphere and the thermosphere.
What is the mesosphere?
400
The solstices occur in these two months, and begin these two seasons. (2X for both)
What are June & December, and Summer & Winter?
400
The amount of energy that reaches any given point on Earth’s surface is controlled by this.
What is the angle of the sunlight as it strikes the surface of the Earth, varying with the seasons? (Caused by Earth's tilt as the Earth revolves around the Sun.)
400
Energy transfer between Earth’s surface and the atmosphere creates this important feature of our life on Earth.
What is weather?
500
A molecule of oxygen containing three oxygen atoms. (3X for where this “layer” is found, and for type of radiation which forms it.)
What is ozone? What is the stratosphere? What is UV radiation?
500
Atmospheric pressure does this as altitude increases. (2X for the name of this type relationship.)
What is decrease? What is inverse relationship?
500
We study these four layers of Earth’s atmosphere. (2X stating the basis for the divisions—the major difference between layers)
What are Troposphere, Stratosphere, Mesosphere, and Thermosphere? What is temperature?
500
As the atmosphere’s density decreases, its buoyancy _______________. (3X for density formula AND the name of this type of relationship.)
What is increases? What is d=m/v? What is inverse?
500
A major cause of weather, this is the major mechanism of energy transfer in the oceans, atmosphere, and Earth’s interior.
What is convection?
