Within 1 billion years, all water will be gone and the average surface temperature will reach 70 °C (158 °F).Earth is expected to be effectively habitable for about another if the nitrogen is removed from the atmosphere.
A "clock" is any geophysical or astronomical process that is changing at a constant rate.
Clocks may be used to estimate how long a process has been taking place.
Below is a list that covers the many different aspects of our planet and what we’ve come to know about.
, who for many years did debate such issues on college campuses, yet because he either "held his own" or won, little by little, evolutionists became unwilling to debate. This is because the facts of science do not support the assertion (or belief) that no intelligence or Intelligent Being was needed to create life and/or its vast and varied forms. Living things are so complex that even people with college degrees in science are realizing that life could not have made itself even in trillions of years.
In essence, it is the largest terrestrial planet, but is smaller and less massive than any of the gas/ice giants of the Outer Solar System.
And with a mean density of 5.514 g/cm³, it is the densest planet in the Solar System.Earth’s axis is tilted 23.439281° away from the perpendicular of its orbital plane, which is responsible for producing seasonal variations on the planet’s surface with a period of one tropical year (365.24 solar days).In addition to producing variations in terms of temperature, this also results in variations in the amount of sunlight a hemisphere receives during the course of a year.Above the Arctic Circle, an extreme case is reached where there is no daylight at all for part of the year – up to six months at the North Pole itself, which is known as a “polar night”.In the southern hemisphere, the situation is exactly reversed, with the South Pole experiencing a “midnight sun” – i.e. This will result in a serious shift in Earth’s habitable zone, as the increased radiation will have a dire effect on life and lead to the loss of the oceans.By 5 billion years from now, the Sun will become a red giant, expanding to 250 times to a radius of roughly 1 AU (150 million km).
