Tides POST TEST

What is a tide?

• an extreme pull from the gravity of the sun.

• something that happens to the ocean every two days.

• a cyclical pattern of temperatures in seas and oceans.

• a continual rise and fall of water in seas and oceans.

What is the moon's role in causing tides?

• Its phases make the tides rise and fall.

• Its gravity causes the water level on Earth to change.

• Its inertia works with its craters to make tides.

• It has no affect at all on Earth's tides.

On which sides of the Earth do high tides occur?

• the sides closest to an farthest away from the moon.

• at the Equator and the Poles.

• only the sides that are closes to the Moon.

• only the sides that are farthest away from the Moon.

What causes high tide on the side of the Earth opposite the Moon?

• The pull of the sun on the side of the Earth opposite the Moon causes a high tide.

• The tilt of the Earth on its axis causes different seasons, such as spring, which create tides.

• The Moon pulls solid Earth toward itself, which makes the water bulge on the opposite side.

• The Oppositional Gravitational Force of the Moon pulls the water on the side farthest from itself.

When the Moon and the Sun are on opposite sides of the Earth, they work together to form an extremely high tide. What is this tide called?

• neap tide

• sweep tide

• spring tide

• neat tide

How do the Sun and Moon work together to create a neap tide?

• by forming a right angle with Earth and creating an extreme gravitational pull.

• by forming a right angle with Earth and canceling out each other's gravitational pulls.

• by aligning on opposite sides of Earth and creating an extreme gravitational pull.

• by aligning on opposite sides of Earth and canceling out each others gravitational pulls.

Which of these is true about how often tides occur?

• All tides occur once a week.

• Tides have no pattern.

• High tides and low tides occur twice a month, a spring tides and neap tides occur twice a year.

• High tides and low tides occur twice a day, and neap tides and spring tides occur twice a month.
