WebAn object at rest in a coordinate system rotating with the earth is subject to a centrifugal force directed outward from the earth's axis and a gravitational force directed toward the earth's center. An observer or an instrument on the earth cannot distinguish between these two forces. Therefore they are combined into a resultant force (25) WebWe have hot summers and cold winters because of the tilt of the Earth's axis. The tilt of the Earth means the Earth will lean towards the Sun (Summer) or lean away from the Sun (Winter) 6 months later. In between these, Spring and Autumn will occur.

This makes the days shorter and colder. The shortest day in this period is called the Winter Solstice. As the earth revolves back towards the summer, it passes through another point where the axis is tilted sideways to the sun. WebThis means that the axis of rotation for the earth is directed almost entirely towards Polaris. They're almost the exact same position. Therefore, when the Earth rotates about its own access, the position of put Polaris remains relatively unchanged. So therefore Option B is the correct option. biltmore lake apartments az
