The obvious answer is one half, although it might actually be very very slightly more than one half, since earth's gravity causes some light to fall beyond the limits that would be defined geometrically.

What portion of earth receives energy form the sun at any given time?

Since the Earth is a Spheroid shape, (not a true sphere) 50% of its surface is illuminated by the Sun, at any given moment.


If the earth has revolved exactly once around the sun since last time how much time pass?

It takes the Earth a year to do this that is 365.25 days.


Will the earth begin to cool if the Earth received more energy than it transmitted over a long period of time?

no, Earth gets more energy than it gives off


How much time does the moon takes to revolve around the earth?

The moon's synodic period, the time it takes to come back to the same phase relative to the Earth and Sun, varies but, on average, is 29.53 days.


Does the surface north or south of the equator receive less heat because Earth's surface is curved?

== == The fact that the surface of Earth is curved definitely has a bearing on how much heat any particular point on Earth's surface receives at any given time. But remember, the axis of Earth is tilted about 23 degrees from perpendicular. As such, the critical point is not always on the equator. The critical point could be anywhere between the Tropic of Cancer and the Tropic of Capricorn, depending on the time of year and the time of day. Every moment of every day, there is a point on Earth, somewhere between the Tropic of Cancer and the Tropic of Capricorn, where for a brief second the sun is directly overhead, 90 degrees from the surface of Earth. That point gets the maximum benefit from the sun's rays for that brief second. The more direct the 'hit' of a ray is to the surface of Earth, means the more of the heat of the ray that gets to the surface of Earth. When a ray needs to penetrate through the atmosphere (and all the other 'ospheres) on an angle, it loses heat. The more the angle is away from 90 degrees to the sun, the more heat is lost. This is often quite noticeable during the course of the day. The morning may begin cool, then it will heat up during the day, and cool off again in the evening. This is all related to the angle at which the sun's rays hit Earth. The tilt of Earth is also the reason for the seasons. The less sunlight that reaches the surface of Earth, the less heat also reaches the surface of Earth. During winter, there are fewer hours of sunlight than in summer, and the angle at which the sun's rays reach Earth is farther away from 90 degrees than in summer.

How much of earth is covered by clouds at any one time?

On average, about two-thirds of Earth's surface is covered by clouds at any given time. Cloud cover can vary depending on location, weather patterns, and time of year.


Why does it gets dark and cold in December and not in July?

It gets dark then because of the tilt of the earth. Luckily, we were just talking about this in my science class. The earth has a tilt, and when it's winter time, we're at the bottom So imagine if this is the earth: /. And this is the sun: o. If the earth is like this: / o. Then the bottom of the earth isn't getting as much sunlight as the top of the earth. It all depends on the rotation and the tilt of the earth.


Why does it get hot and cold?

the earth gets hot in cold because of the earths tilt in the summer time most of the sun is on the earth in the winter time less of the sun is on the earth


How much of the Moon's surface is illuminated by the sun at any time regardless of how much of that light can be seen from earth?

At any given time, one half of the Moon's surface is illuminated by the sun, just like on Earth. The portion of the Moon's illuminated side that we can see from Earth depends on its position in its orbit around our planet.


The majority of water on Earth at any given time is found in?

The oceans.


How much of earth is in daylight at any given time?

Approximately half of the Earth is in daylight at any given time due to its rotation on its axis, with one side facing the Sun (daytime) and the other side facing away (nighttime). This is why we experience day and night cycles throughout the day.

What determines the time of a given location on earth?

The time of a given location on Earth is determined by its position within a time zone. Time zones are based on longitudinal lines and are typically one hour apart. The time is also influenced by whether the location observes daylight saving time.
