Answers
Answer:
1). Effect on the Direction of the Wind. The wind is the movement of air in a particular direction. ...
Cyclones. ...
Ocean currents. ...
Change of day and night.
2). If the Earth were to stop spinning on its axis, gradually the oceans would migrate towards the poles from the equator. ... You could travel around the Earth on the equator and stay entirely on dry land—ignoring the freezing cold on the night side, and the searing heat on the day side.
3). It takes approximately 365.25 days for Earth to orbit the Sun — a solar year. We usually round the days in a calendar year to 365. To make up for the missing partial day, we add one day to our calendar approximately every four years. That is a leap year.
4). The day that the Earth's North Pole is tilted closest to the sun is called the summer solstice. This is the longest day (most daylight hours) of the year for people living in the northern hemisphere. It is also the day that the Sun reaches its highest point in the sky.
The winter solstice, or the shortest day of the year, happens when the Earth's North Pole is tilted farthest from the Sun.
In between, there are two times when the tilt of the Earth is zero, meaning that the tilt is neither away from the Sun nor toward the Sun. These are the vernal equinox — the first day of spring — and the autumnal equinox – the first day of fall. Equinox means "equal." During these times, the hours of daylight and night are equal. Both are 12 hours long. Check out the chart below to see how the solstice works.
