What is the name for the change in a stars spectrum when it moves away from the earth?
The change in a star's spectrum when it moves away from the Earth is called redshift. This shift occurs because the wavelengths of light emitted by the star are stretched out as the star moves away, causing the light to appear more red.
Do rainbows appear in the same place on different days?
If you are in the same place, the rainbow will always appear in the same place because it all has to do with the angle you are at in relation to the sun (42 degrees - see the related link). So if you are always in the same spot (e.g. at your desk at work), the sun will be coming from the same same angle, creating the rainbow in the same spot. My understanding of what I've read, you'll only see a rainbow in a certain place in the sky from the same spot at a certain time of the year because the sun moves depending on the season. Also, it is not only the angle of the sun but also the height of it that has to be the same.
What way does the earth moves?
The Earth moves in two main ways: rotation on its axis, which causes day and night, and revolution around the sun, which determines the length of a year. Rotation takes about 24 hours, while revolution takes about 365 days.
What is the type of fault where a hanging wall block moves up relative to the footwall block with a dip of greater than 45 degrees?
That type of fault is called a reverse fault. Reverse faults are characterized by the hanging wall block moving up and over the footwall block at a steep angle, typically greater than 45 degrees.
International Date Line The term for the boundary between night and daylight on the Earths surface is?
The International Date Line marks the boundary between two consecutive calendar days, creating a difference in time of up to 24 hours. This imaginary line generally follows a meridian of longitude in the Pacific Ocean and helps account for the Earth's rotation and time differences across the globe.
How many degrees of longitude does the sun appear to move each hour if it move 360 in 24 hours?
The sun appears to move 15 degrees of longitude each hour if it moves 360 degrees in 24 hours. This is because there are 24 hours in a day, so dividing 360 degrees by 24 hours gives us 15 degrees per hour.
How many degrees of longitude does the sun appear to move each hour if it moves 370 degrees in 24 hours?
Any number you like. Since the predicate statement: "the sun appears to move 370 degrees in 24 hours" is FALSE, then the "conclusion" can be any statement you like. The sun appears to move 360 degrees in 24 hours and so 360/24 = 15 deg each hour.
How many degrees does the hour hand move in 6 hours?
The hour hand of a clock completes one full revolution, or 360 degrees, in 12 hours. Therefore, in 6 hours, it moves half of that distance. To calculate this, you can divide 360 degrees by 12 hours to get 30 degrees per hour, and then multiply by 6 hours. Thus, the hour hand moves 180 degrees in 6 hours.
How many degrees does the sun move in four hours?
The sun appears to move about 60 degrees in four hours. Of course, the sun is not moving, the earth is rotating making it appear to ancient people the sun is moving.
How long does it take the hour hand to move 90 degrees?
It moves 360 degrees every 12 hours, so for 90 degrees that is 3 hours
How long does it take the hour hand to move to 6 degrees?
The hour hand moves 360 degrees in 12 hours so 6 degrees takes 0.2 hours = 12 minutes.
How many degrees does the little hand move in 3 hours?
5
Why do the stars appear to move 360 degrees in 24hours?
The stars appear to move 360 degrees in 24 hours due to the Earth's rotation on its axis. As the Earth spins, it creates the illusion that the stars are moving across the sky. This motion is what gives us day and night cycles.
180 degrees longitude?
180 degree longitude or 0 degree longitude means the same thing. Now when someone crosses this line one has to make some changes in the time e.g when one crosses this line and moves towards east it will gain one day, if one crosses and moves towards the west then one losses one day
How many minutes are in one degree longitude or latitude?
60 minutes in each degree. The International Date Line is at around +180° longitude. If we start moving to the West from +180° longitude after 6 hours we will reach at +90° longitude position and after 24 hours we will reach at -180° longitude which is nothing but our starting position. In this time (24X60=1440 minutes) our Planet moves 360° in total. Now it is clear to realize that 1° equivalent to 4 minutes.
What longitude and latitude is Antarctic circle?
The Antarctic Circle is a line of latitude -- which moves, according to the Earth's wobble. As of 10 March 2016, it runs 66°33′46.1″ as a line of latitude and crosses all degrees of E and W longitude on Earth.
How many degrees does the hour hand move in one half of an hour?
It takes twelve hours for the hour hand to move 360 degrees In half an hour the hour hand moves 15 degrees
