Over geological time, the Earth's average temperrature has increased and decreased.
Think of the 'Ice Ages' , when the Earth was much colder, with larger polar ice caps. and intervening warm periods, when the Earth was much warmer.
There was no Industrial Activity or motor cars etc., to drive these changes. So it is thought that the Sun and the Earth's atitude on its spacial movement around the Sun , was the main driver for these variations.
The current 'hysteria' of climate warming/change is just a natural warming. Mankind does not fully understand the larger periodical mechanics behind this process., but it happens.
So , YES!!! The Earth's mean temperature does change over time.
What else can I help you with?
Are the moon and the sun the same distance from earth?
No, the moon and the sun are not the same distance from Earth. The average distance from the Earth to the moon is about 238,855 miles, while the average distance from the Earth to the sun is about 93 million miles.
Since the moon always keeps the same side facing earth does it rotates on its on axis?
Yes, it rotates at the same rate it orbits the Earth.
Because the moon rotates once for each revolution around earth?
The moon is tidally locked with the Earth, meaning that it rotates on its axis at the same rate that it orbits the Earth. This synchronous rotation is why we always see the same side of the moon facing towards Earth.
Do you always see the same side of the moon from eath?
The answer is yes. We always see the same side of the moon from the Earth because the time it takes the moon to circle the Sun is the same as the time it takes to circle itself.
What is the average temperature on Earth?
Well, hello there, my friend. The average temperature on Earth can be a tricky thing to pin down since it varies depending on where you are. Generally speaking, though, the average temperature across the entire globe is about 59 degrees Fahrenheit (15 degrees Celsius). But remember, nature has its own way of dancing to its own beat, so this number can shift like clouds in the sky. How magical is it to know that our planet has so many hues in its temperature palette?
Why does the area around the equator stay same temperature year round?
The equator faces always the sun wheather the earth is tilted to the north or south. This causes the earth to stay the same temperature all time.
Which two months shown have the same average temperature?
March and April have the same average temperature.
Do two gases at the same temperature have the same kinetic energy?
Yes, two gases at the same temperature have the same average kinetic energy. Temperature is a measure of the average kinetic energy of the particles in a substance. Therefore, if two gases are at the same temperature, their particles have the same average kinetic energy.
If two glasses of water are at the same temperature the average is?
The average would be the same temperature as the two glasses of water.Using the following formula for finding the average temperature this is proven.(Temperature of glass one) + (Temperature of glass two) / (number of glasses) = Average
The Moon's average density is about the same as the density of which of the Earth's layers?
The moon's average density is about the same as the density of mantle of the Earth.
What is the overall rise in earth's average temperature called?
The rise in temperature is called Global Warming. This global warming of the earth is causing Climate Change. These two things are not the same thing.
What is the temperature of the inside of earth?
The same temperature as the rock in which it sits (the aquifer).
Does mars have the same temperature as earth?
No, its colder.
How cold is Saturn than earth?
At the level at which the atmospheric pressure on Saturn is the same as the pressure on earth, the temperature is around 134°K (-139°C). Earth's average temperature is 287°K (14°C). Earth is 153°C warmer. Saturn gets warmer as you move closer to the core.
What is the average temperature for gold?
Same as for everything else - called the ambient temperature.
What is the reason why the same side of the moon always faces the earth?
The same side of the moon always faces the earth because of a phenomenon called tidal locking, where the moon's rotation period is the same as its orbit around the earth. This causes one side of the moon to always be facing towards the earth.
Are the moon and the sun the same distance from earth?
No, the moon and the sun are not the same distance from Earth. The average distance from the Earth to the moon is about 238,855 miles, while the average distance from the Earth to the sun is about 93 million miles.
