Where is the tidal bulge?
On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean's waters toward it, creating one bulge. On the far side of the Earth, inertia dominates, creating a second bulge. In this way the combination of gravity and inertia create two bulges of water.
What is a tidal bulge quizlet?
The water on the side closest to the Moon is closer to the Moon than the center of gravity of the Earth and so the Moon exerts more pull on that water and it bulges out (high tide).

So the part facing the moon is pulled away from the center creating a bulge and thus increasing the sea level and causing a high tide.
What happened to the tidal bulges?
The bulge on the far side of the Earth is caused by inertia. The water moving away from the moon resists the gravitational forces that attempt to pull it in the opposite direction. Because the gravitational pull of the moon is weaker on the far side of the Earth, inertia wins, the ocean bulges out and high tide occurs.
How many tidal bulges are there?
two tidal Since the Earth rotates through two tidal “bulges” every lunar day, we experience two high and two low tides every 24 hours and 50 minutes.
What causes tidal bulges quizlet?
The pull of the moon's gravity on Earth's water causes tidal bulges to form on the side closest to the moon and farthest from the moon. In the place where there are tidal bulges, high tide occurs along coastline.
What would happen if Earth had no moon?
The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days. Without the moon, tides would fall, nights would be darker, seasons would change, and the length of our days would alter.
Which phenomenon causes the oceans to bulge?
The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.
Does centrifugal force cause tidal bulge?
The tidal bulge on the far side of the earth is not caused by centrifugal force. It is caused by the exact same thing the near-side bulge is caused by: the moon's gravity. Furthermore, tidal effects are not caused by the overall strength of gravity like planetary orbits are.
Are tidal bulges equal?
The moon's gravitational attraction exerts a retarding torque on those tidal bulges. This is in a direction to reduce the earth's angular momentum and gradually slow the earth's rotation. The bulges also exert an equal size and oppositely directed torque on the moon, gradually increasing its angular momentum.
What are tidal forces caused by?
High and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon.
What astronomical body causes the largest tidal bulge on Earth?
Based on its mass, the sun's gravitational attraction to the Earth is more than 177 times greater than that of the moon to the Earth. If tidal forces were based solely on comparative masses, the sun should have a tide-generating force that is 27 million times greater than that of the moon.

What causes the ocean to bulge near the equator compared?
The equatorial bulge affects the ocean, too—sea levels are slightly higher in equatorial regions than near the poles. The equatorial bulge is created by the Earth's rotation. As lines of latitude increase in size, a point has to travel faster to complete a circle (revolution) in the same amount of time.
Do tides cause the Coriolis effect?
Another influence on waves, tides, and ocean currents is the Coriolis effect. Earth is constantly rotating towards the east and the speed of Earth's rotation varies greatly at different latitudes.
What are the three forces that cause tides?
The tide-raising forces at the earth's surface thus result from a combination of basic forces: (1) the force of gravitation exerted by the moon (and sun) upon the earth; and (2) centrifugal forces produced by the revolutions of the earth and moon (and earth and sun) around their common center-of-gravity (mass) or …
Do black holes stretch you?
Your feet feel a stronger gravitational pull than your head, because they are closer to the black hole. As a result, your body is stretched apart. For small black holes, this stretching is so strong that your body is completely torn apart before you reach the event horizon.
How many tidal bulges occur at any one time?
two tidal Because the Earth rotates through two tidal “bulges” every lunar day, coastal areas experience two high and two low tides every 24 hours and 50 minutes. High tides occur 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high.
Why don’t we feel the Earth rotating?
But, for the most part, we don't feel the Earth itself spinning because we are held close to the Earth's surface by gravity and the constant speed of rotation. Our planet has been spinning for billions of years and will continue to spin for billions more. This is because nothing in space is stopping us.

How cold would Earth be without the Sun?
For us on earth, it is a source of life. Even in Antarctica, the coldest place on our planet, temperatures seldom drop below minus 50°C. Without the sun's radiation, the temperature would be anywhere near the absolute zero of minus 273°C. Life would have never continued nor even have come into existence.

Why is Earth bulge at Equator?
This bulge exists because of a force created by Earth's rotation. As a result, a person on the equator is over 13 miles farther from Earth's center than a person on the North Pole is.
What are Earth’s three different tidal patterns called?
There are generally three types of tides: diurnal – one high and low tide each day, semi-diurnal – two high and low tides each day, and mixed – two high and low tides each day of different heights.
Why does the Earth rotate from west to east?
The Sun, the Moon, the planets, and the stars all rise in the east and set in the west. And that's because Earth spins toward the east. Because of the Earth's magnetic field, it rotates from west to east.
What are tides 7?
Answer: The rhythmic rise and fall of ocean water, twice in a day, is called a tide. Tides are caused by the gravitational force exerted by the sun and the moon on the earth's surface.
Would spaghettification hurt?
Either way, spaghettification leads to a painful conclusion. When the tidal forces exceed the elastic limits of your body, you'll snap apart at the weakest point, probably just above the hips. You'll see your lower half floating next to you, and you'll see it begin to stretch anew as tidal forces latch onto it.
Do wormholes exist?
Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They've never been seen, but according to Einstein's general theory of relativity, they might exist.
Why is the tidal bulge in front of the moon?
The Short Answer: High and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon.
