The Moon's speed is very constant. There are 2 kinds of acceleration: Linear and Centripital. Centripital acceleration is experienced by a body orbiting another body, like the Moon orbits the Earth, but it does not mean speeding up.
fairly big
Red giants.
It's a fairly cool star
It just stays there waiting to be used-the sun has enough to last many billions of years and luckily for us the rate of burning has stayed fairly constant so far, but eventually it will run out of hydrogen and die.
No. Only the most massive main sequence stars are blue. Because blue stars are short-lived compared to other stars they are almost invariably young. Less massive stars live much longer, so only a fairly small portion of them are so young. For example a star like our sun can be expected to remain on the main sequence for about 10 billion years, if the rate of formation of such stars is constant then you can expect 1 in every 1,000 such stars to be in their first 10 million years on the main sequence.
Yes, the moon is accelerating as it revolves around the Earth, even though it moves at a fairly constant speed. This acceleration is due to the change in direction of the moon's velocity as it travels along its circular orbit. In physics, acceleration is defined as any change in velocity, which includes changes in speed or direction. Thus, the moon is experiencing centripetal acceleration directed towards the Earth.
fairly constant
Yes, it remains fairly constant.
its fairly constant,increasing only 0.2% at the peak of each 11 year solar cycle.
It is the stratosphere atmospheric zone where the temperature stays fairly constant, at -60 degrees Celsius. The stratosphere layer contains the ozone layer.
Blizzards in Antarctica are fairly constant.
loess
fairly constant
true
If you consider blizzards as storms, they are fairly constant on Antarctica.
They tend to move at a fairly constant rate. The only major changes happen with earthquakes.
