Is dictated only by the gravitational attractions of the sun and the moon?
Tidal range a. is dictated only by the gravitational attractions of the Sun and the Moon.
Where is the largest tidal range located and what is the range?
The highest tides in the world can be found in Canada at the Bay of Fundy, which separates New Brunswick from Nova Scotia. The highest tides in the United States can be found near Anchorage, Alaska, with tidal ranges up to 40 feet .
Why are some tidal ranges larger than others?
Some places have a larger tidal range than others because of differences in the shape of the ocean floor. At times when the Sun, Earth, and Moon are in line with each other (during full and new moons), the tidal range is larger because both the Sun’s and Moon’s gravitational pull create the tide.
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. At the first and third quarters of the moon, the sun and moon pull at right angles to each other. This produces a tide with the least difference between low and high tide.
What causes high and low tides quizlet?
What causes tides? The force of gravity pulls the moon and Earth (including the water on Earth’s surface) toward each other. Tides are caused mainly by differences in how much the moon’s gravity pulls on different parts of Earth.
Which is the larger of the two tidal bulges quizlet?
The solar tidal bulges are larger than the lunar tidal bulges because the Sun is larger than the Moon.
What kind of tide does the observer experience as he passes through a tidal bulge?
There are 3 tidalbulgesof water around the earth. B. What kind of tide does the observer experience as he passes through a tidal bulge? The observer experienced a high tide through the tidal bulge.
Why are there two high tides on Earth every day quizlet?
The eastern coast of North America has two high tides and two low tides every day. The moon’s gravitational force pulls on the ocean water and creates a tidal bulge on one side of Earth. The pull on the water on the other side of Earth is weaker, so a bulge forms there, also.
What causes stars to form quizlet?
Stars form primarily from the collision of other stars. Gas pressure is the main source of pressure support against gravity in a main sequence star.
What happens first when a star begins to run out of fuel quizlet?
When a star begins to run out of fuel, its core shrinks and its outer portion expands. Depending on the size the star changes to either a giant or supergiant star.
What force causes a star to form from a nebula quizlet?
gravity
What causes a star to shine brightly quizlet?
What causes a star to shine brightly? The star’s core shrinks. The star becomes a black hole. The star becomes a white dwarf.
What causes a star to shine brightly?
Stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars. In most stars, like our sun, hydrogen is being converted into helium, a process which gives off energy that heats the star.
What color is the hottest star?
Blue stars
How do spectrographs help astronomers classify stars quizlet?
The astronomers use the spectrographs to classify the stars on the basis of the composition of the elements present in them. The element present in them absorbs all the wavelengths of light and reflects back the wavelength which is not absorbed by the element.
What are the 7 main types of stars?
There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M. O and B stars are uncommon but very bright; M stars are common but dim..
What three things are used to classify stars?
Astronomers classify stars according to their physical characteristics. Characteristics used to classify stars include color, temperature, size, composition, and brightness. Stars vary in their chemical composition.
Which star is hotter Mira or the sun?
Mira is hotter and bluer but intrinsically fainter than the Sun.
Which star has a higher temperature?
Type O stars
Where does the sun fit in this diagram?
Our Sun is a fairly average star and sits near the middle. A plot of the nearest stars on the HR diagram is shown below: Most stars in the solar neighborhood are fainter and cooler than the Sun.
Which star is larger in size North Star or the sun?
Scientists using a new telescope found the size of the North Star, also known as Polaris. It turns out that Polaris is 46 times larger than the Sun. It is no surprise to scientists, because Polaris is a cepheid star.
What is the biggest star we know of?
Pistol Star
What is the biggest star in the universe 2020?
UY Scuti
What is the largest star in the Universe 2020?
The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun. And it’s not alone in dwarfing Earth’s dominant star.
What is the biggest thing in the universe?
The largest known structure in the Universe is called the ‘Hercules-Corona Borealis Great Wall’, discovered in November 2013. This object is a galactic filament, a vast group of galaxies bound together by gravity, about 10 billion light-years away.
Which is bigger sun or star?
It turns out that our Sun is an average sized star. We have found stars that are 100 times bigger in diameter than our sun. Truly, those stars are enormous. We have also seen stars that are just one tenth the size of our sun.
How many Earths can fit in the biggest star?
1 Answer. About 7.5477×1010 earths can fit in VY Canis Majoris.
Can you fit 1 million Earths in the sun?
It holds 99.8 percent of the solar system’s mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun. The sun is relatively young, part of a generation of stars known as Population I, which are relatively rich in elements heavier than helium.
How many Earths can fit in our sun?
1.3 million Earths
How many Earths can fit in the universe?
By dividing the two volumes we get a factor of 3.2⋅1059, or written as decimal number: The observable comoving volume of the universe is about 000,000-times the volume of Earth.
