Sky Science #2 Flashcards
What is one fact about each layer of the earth’s atmosphere?
Troposphere: This is where weather happens
Stratosphere: It contains the Ozone (O3) layer
Mesosphere: Protects us from meteor and other space debris. Coldest layer of the atmosphere (-88°)
Tremosphere: This is the hottest layer of the atmosphere. Contains fewest air molecules
Ionosphere: The northern lights are created in this layer by the electrically charged ion
Exosphere:satellites orbit in this layer thermosphere
What are the names of the layers of the Earth’s atmosphere?

Why does the sun appear to move across the sky each day?

What is the difference between direct and indirect ( slanting ) rays from the sun? What causes the rays become more or less direct?
The difference between direct and indirect raise our direct rays are warmer/summer indirect Rays are colder/winter
The Rays become more or less indirect by the tilted earth or how far away you are from the sun
What are the two reasons that earth experiences for different seasons each year?
Tilt to be earth/revolution (orbit) around the sun
When do the spring and fall equinoxes occur? When do the summer and winter solstice a cook corn? What happens to the amount of daylight on each of the states? What causes solstices and equinoxes?

Winter solstice December 21 shortest day
fall equinox September 21 day/night 12/12
spring equinox March 21 day/night 12/12
The revolution around the sun causes the solstices and equinoxes
