Why does the Earth revolve around the Sun?
It has the most gravity in our solar system
100
How many high tides are there each day?
2

What are 2 hemispheres on Earth? Which one do we live in?
Northern Hemisphere and Southern Hemisphere. We live in the Northern Hemisphere
100
What two factors impact water density?
Salinity and Temperature
100
How does air move?
Air moves from an area of high pressure to an area of low pressure
200
What does the Sun revolve around?
A black hole in the center of the milky way
200
What are the Moon phases when it is a spring tide?
New Moon & Full Moon
200
How do we get day and night?
When we face the Sun we have day, when we turn away from the Sun we have night.
200
How do ocean currents affect climate?
Places near warm currents are warmer than they would be without the current there
Places near cold currents are cooler
200
What two factors cause wind movement?
The change in pressure/density & the coriolis effect
300
Where on the Earth are the Sun's rays the strongest?
Around the equator
300
What causes a high tide?
When the space on Earth passes through the area closes to the Moon
300
How long does it take the Earth to rotate once?
24 hours
300
What is the Gulf Stream?
A warm ocean current that brings the weather up the east coast of the United States.
300
What kind of weather is at a low pressure system?
These pressure systems form clouds and sometimes precipitation - rain or snow
400
Revolution speed decreases as you move farther away from the sun, why is this?
the suns gravity decreases as distance increases
400
What are the Moon phases that create neap tides
first and third quarter moon
400
How long does it take for the Earth to revolve around the Sun?
365.25 days
400
What is a gyre?
A circular current that causes trash to collect.
400
What kind of weather is at a high pressure system?
These pressure systems bring clear skies and fair weather
500
Why don't people on Earth get attracted through gravity to the Sun instead of Earth since the Sun is more massive than Earth?
Earth is less massive but significantly closer
500
Draw a tidal bulge and explain what is happening at each part
500
How do we get our seasons?
When we are tilted away from the Sun we are in winter because the Sun's rays aren't as strong. When we are titled toward the Sun we have summer.
500
What do the deep ocean currents move?
This allows for nutrients to move back up to the top layers of water & oxygen to be circulated back down to lower layers
500
How are air masses classified?
Air masses are classified by their temperature and moisture characteristics.
