The way water returns to Earth as rain, snow, sleet or hail.
100
What is the source of energy for the water cycle?
The Sun
100
How do waves form?
Most common waves are started by wind, but other are cause by earthquakes.
100
What is high and low tide?
High tide is when the water is at its highest point and low tide and when the water is at its lowest point.
200
What is condensation?
When water vapor cools and condenses into liquid water, connecting to tiny dust particles in the atmosphere, forming clouds.
200
What is a wave?
The movement of energy through a body of water.
200
Rain, snow, sleet, and hail are forms of what?
Precipitation
200
What happens to wavelength has waves get closer to shore?
The wave length gets shorter.
200
How many low tides are there a day?
How many high tides are there a day?
There are 2 low tides and 2 high tides each day.
300
What is wavelength?
The distance between 2 waves.
300
What is wave height?
The vertical distance from the crest (top of wave) to the trough (bottom of wave).
300
What in gas form in the atmosphere is known as _______ _______.
water vapor.
300
What happens to the wave height as it gets closer to shore?
The waves get higher.
300
What causes high and low tide?
The position of the moon and sun and the pull of gravity on Earth's water.
400
What is rip current?
A rush of water that flows rapidly back to the ocean/sea.
400
What is tide?
The rise and fall of Earth's water on its coastlines.
400
True or false? More than 97% of the water on Earth is fresh water.
False
400
In what direction does a rip currents pull swimmers?
Out into the ocean
400
What is the position of the Earth, moon, and sun for spring tides.
They are in a straight line.
500
What are spring tides?
A tide with greatest distance between the heights of high and low tide.
500
What are neap tides?
A tide with the least difference between low and high tide.
500
Describe the water cycle?
It is never ending. Water evaporates from Earth and goes to the atmosphere as water vapor. The water vapor goes through condensation and forms clouds. The clouds then put water back to Earth in different forms of precipitation.
500
Explain how both a wave's energy and the water in a wave moves?
The energy moves towards shore, while the water moves up and down in a circular motion.
500
What is the position of the Earth, moon, and sun for neap tides?
