because the earth is spinning and as it spins the sun appears to move.
You should run it only when it's display tells you the air is humid.
Time is related to the orbit of the Earth as well as the Earth's rotation around the Sun. This is because as the Earth rotates on its own axis we are moving from what is considered daytime and nigh time. Daytime being when there is sunlight and night time when there is no sunlight. It takes 24 hours for the Earth to complete one rotation. As the Earth turns on its axis, it is also orbiting the Sun, this helps to create our seasons. The seasons are determined by how close or how far any hemisphere is from the sun. It takes 365 days for the Earth to complete an orbit around the Sun.
It's always daytime over 50% (half) of the earth.When a solar eclipse occurs, anybody who is in a position to see it is on the daytime partof the earth. Obviously, if something is happening to the sun and you can see it in the sky,then it must be daytime where you are.When a lunar eclipse occurs, only the people on the night-time part of the earth can see it.But for a lunar eclipse, everybody on the night-time part of the earth can see it.
During the day, the sun heats the desert - making it extremely hot. At night, the heat simply dissipates.
Daytime occurs when the Earth rotates on its axis, causing the side facing the Sun to experience daylight. As the Earth spins, different parts of the planet are exposed to sunlight, creating the cycle of day and night.
The temperature range of the planet Mercury is from 350 degrees in the daytime to 170 degrees at the nigh-time. The temperature range of the metal mercury is from −38.83 °C to 356.73 °C.
I think this is how you use nigh in a sentence: "It was a cold evening but morning was nigh." Hope this helps!!
It always display daytime
When you are nocturnal you sleep at daytime and you're awake at nigh time.
Because in the daytime the earth is tilted to where it gets more direct sunlight, while in the night time the earth is tilted to where sunlight is not direct and it's turned away from the sun so the temperture lowers.
Any time during the night. Never during the daytime.
The position of the sun appears to change over a day as it rises in the east, reaches its highest point at noon, and sets in the west. This apparent motion is due to the rotation of the Earth on its axis.
