How is the Sun the major source of energy in the water cycle?
It provides the energy to condense atmospheric water vapor into rain.
It provides the energy to evaporate water on Earth into the atmosphere.
It provides the energy to create winds that blow air masses across Earth.
It provides the energy needed for water to be transported downhill from mountains to rivers and oceans.
What comes after runoff in the water cycle?
Evaporation
Condensation
Precipitation
Collection
What step comes after infiltration in the water cycle?
collection
groundwater
transpiration
runoff
Why does rain fall to the ground?
The extreme heat in the atmosphere causes the water vapor to get less dense. Gravity pulls it to the ground.
The wind blows the clouds together, causing storm clouds to form and start raining.
The temperature in the atmosphere cools enough so that the water vapor gets more dense. Gravity pulls it to the ground.
The sky gets warmer the higher up you go, so the clouds are evaporated back into liquid form.
Which process in the water cycle forms clouds?
Evaporation
Condensation
Precipitation
Runoff
If we start with the ocean, what is the order of the steps in the water cycle?

Which term applies to water that falls on land and flows towards a body of water?
Condensation

Runoff
Collection

Why does the Moon have a greater gravitational pull on Earth’s water than the Sun?
The Moon is smaller than the Sun.
The Moon is closer than the Sun.
The Moon has a greater density than the Sun.
The Sun is made of gas.
What causes the water to bulge out on the side of the Earth that faces the Moon?
The Moon is closest to that side, so its gravity has stronger pull on the water.
The water is being pushed towards the Moon by Earth’s gravity.
The Moon pushes the Earth away, causing the water to splash.
The waves are bigger on that side of the Earth.
What happens during Spring Tides?
The Moon is at a right angle to the Sun and Earth, weakening the gravitational pull and causing very little difference between high and low tides.
The sea level rises because the Moon is pulling the water on Earth's surface towards it.
The Earth, Moon, and Sun line up, and the combined gravity of the Moon and Sun cause the highest high tides and lowest low tides.
The sea level lowers because the Moon is pulling the water on Earth's surface in the opposite direction as usual.
What happens during Neap Tides?
The Earth, Moon, and Sun form a right angle, weakening their gravitational pull and causing very little difference between high and low tides.
The sea level rises because the Moon is pulling the water on Earth's surface towards it.
The Earth, Moon, and Sun line up, and the combined gravity of the Moon and Sun cause the highest high tides and lowest low tides.
The sea level lowers because the Moon is pulling the water on Earth's surface in the opposite direction as usual.
What is the order of the ocean zones from top to bottom?
Sunlit Zone, Dark Zone, Twilight Zone, Abyssal Zone
Twilight Zone, Sunlit Zone, Dark Zone, Abyssal Zone
Sunlit Zone, Twilight Zone, Dark Zone, Abyssal Zone
Abyssal Zone, Dark Zone, Twilight Zone, Sunlit Zone
What determines the names of the ocean zones and how they are separated?
Temperature in each zone
How much sunlight reaches each zone
The pressure in each zone
The volume of water in each zone
As you dive farther down into the ocean, how would the light, temperature, and pressure change?
light decreases, temperature and pressure increase
temperature stays the same, pressure increases, light decreases
light and temperature decrease, pressure increases
temperature, light, and pressure all decrease
Which zone has the most visible sunlight and supports a wide variety of living things?
