Investigation #1
The Sun
The Sun
Earth rotates on an imaginary line called what?
Axis
We see all of the Moon when it is a:
Full Moon
Weather happens in the _______ layer of Earth's Atmosphere.
Troposphere
Things that are more dense, do what?
Sink
The gaseous state of water is called what?
If revolution is "To travel around something in a circular path; orbit" then what is rotation?
Turning around on an axis.
Waxing means _________ while waning means _________.
Waxing = growing larger
Waning = growing smaller
What weather instrument measures air pressure?
Barometer
Whats the main difference between air and water particles?
Air particles move around a lot and aren't constantly touching, they do bump into each other thought. Water particles are flowing, but always touching.
Most of Earth's fresh water is found where?
In ice caps and glaciers
On a sunny day, what time would you see your shortest shadow?
Noon, when the Sun is at it highest position in the sky.
About how long does one full lunar cycle (moon phases) typically take?
4 weeks
The hydrosphere is all of the _____ on Earth.
Water!
In GREAT detail, how is Earth warmed?
The Sun warms the Earth through the Geosphere and Hydrosphere first, those then come in contact with the air, warming it!
Most of the Earth's water is made up of:
The Ocean/salt water
Night is the side of Earth that is:
Facing away from the Sun.
If someone were to tell you that our Sun, a star, is the biggest and brightest, what would you say to them. Please explain with great detail.
No, our Sun, a star, is not the biggest in brightest star. It only appears that way because it is so close to us. There are MANY larger and brighter stars, they're just so much further away from us than our star, the Sun!
What two gases are the most plentiful in Earth's atmosphere?
Nitrogen and Oxygen
Wind is caused by what?
Cold dense air flowing towards/into warm less dense air.
What is the difference between evaporation and condensation?
Evaporation: Water to gas
Condensation: Gat to water
What two motions are the reason that there are more daylight hours in the Summer?
1. Earth orbiting the Sun
2. Earth rotating on its tilted axis
Why don't we see the same stars all year long?
For something to be 'matter' it means what two things?
1. It takes up space
2. It has a mass
How do warm and cool air particles differ? I need three ways!
Cool: more dense, sink, a little closer together
Explain, in great detail, a 5+ step water cycle that a droplet could take. It needs to go at least 5 different places and they need to be in an order that could really happen.
