What is the name of a day when the day and night are equally long?
The day when day and night are equally long is called an equinox. There are two equinoxes each year: the vernal equinox, which occurs around March 20 or 21, marking the beginning of spring in the Northern Hemisphere, and the autumnal equinox, occurring around September 22 or 23, signaling the start of autumn. During these times, the Earth's tilt is such that the sun is directly above the equator.

What happens when the north end of earths axis is tilted torward the sun?
When the North Pole is tilted toward the sun, the northern part of the earth has long days and short nights.The tilting of the Earth on its axis is what gives us the changing seasons. When the North Pole tilts towards the Sun, it is summer in the northern hemisphere and winter in the southern hemisphere.
What is the deflection of objects in the northern hemisphere?
In the northern hemisphere, objects moving over long distances are deflected to the right due to the Coriolis effect, which is a result of the Earth's rotation. This phenomenon influences weather patterns, ocean currents, and the trajectory of projectiles. For example, winds in the northern hemisphere curve clockwise around high-pressure systems and counterclockwise around low-pressure systems. The effect increases with the speed of the moving object and the distance traveled.
