Planet Earth

Earth travels approximately 584 million miles in its orbit around the Sun every year.

The most complex forms of life, such as animals, began to appear during the Cambrian period around 541 million years ago. This period is often referred to as the "Cambrian Explosion" due to the rapid diversification and emergence of various complex organisms.

Space itself does not have gravity, as gravity is a force produced by mass. In space, the gravity experienced depends on the mass of nearby objects, such as planets or stars. If you are far away from any massive objects, you would experience very little gravity, while being close to a massive object would result in stronger gravity.

There are countless individuals and organizations working to help protect the Earth and mitigate environmental damage. These people engage in activities such as conservation efforts, recycling, sustainable living practices, and advocating for policy changes to protect the planet. Global movements like Fridays for Future and Earth Day also mobilize millions of people to take action for the environment.

Any constellation is a group of stars that appear to form some kind of pattern,

but have no connection with each other. They all happen to be in roughly the

same direction from us, but they're all at different distances. So there's no

such thing as a constellation's distance from us.

Water. There is overall 70% water and only 30% land.

However, 97% of water is saltwater, and the other 3% is fresh. Since 2% of that fresh water is frozen in the arctic, we humans can only use 1% for drinking.

earths mass = 5.974 * 10^24 kg, so 1 percent = 5.974 * 10^22 kg

It's roughly a 70.1%/29.9% split in favor of the oceans.

Earth's rotation, known as the Coriolis effect, influences the direction of the jet stream by causing it to meander from west to east in the upper atmosphere. This effect results in the jet stream following a wavy, meandering path as it travels around the globe.

It should deteriorate gradually, if only due to energy lost through the emission of gravitational waves. But this effect is so small that it will not be the greatest of our worries for the future of Earth. Way before it becomes significant, there will be other, more significant problems.

The stratosphere starts about 10 kilometers (6.2 miles) above the Earth's surface and extends up to about 50 kilometers (31 miles) high.

Gravity is the force that pulls everything towards the center of the Earth. This force is created by the mass of the Earth and all objects on or near its surface.

The Earth circles the Sun in an orbit about 584 million miles long (940 million km).

(multiply 93 million miles x 2 x 3.1416)

You can also calculate this by using the Earth's average orbital speed of 29.8 km/sec.

This is roughly 66661 miles per hour x 24 hours per day x 365.25 days per year.

nobody really knows. Anything could have happened to that rock in 65.5 million years. Remember that there are also other theories about the K-T extinction event, though, an asteroid impact is by far most widely believed. If it where possible to find that particular rock, it would be a fact, not a theory.

The Earth's center, or a point very close to it inside the Earth, is exactly

following the orbit. So there are always two points on the surface that are

exactly on the orbit. It seems to me that these points would have to be in

the Tropics, and would have to move along the surface as the Earth turns.

It's not possible for ANY point on the surface to ever be more than about

6,200 miles from one of these points where the orbit actually meets the

surface.

Yes, the Earth's rotation occurs on an imaginary line running through its North and South Poles called its axis. This axis is tilted at an angle of approximately 23.5 degrees relative to its orbit around the Sun, leading to the changing seasons.

It is difficult to predict exactly how long the earth's tungsten supply will last because it depends on various factors such as demand, extraction rates, and new discoveries. However, current estimates suggest that there are enough tungsten reserves to last for several hundred years at current consumption rates.

Earthlink is an internet service provider that has been around since the early days of the internet, in the mid-90s. They are currently supporting all forms of internet connection, and since 2006 have been working on a project to provide free wi-fi to major cities.

w=mg

gravity is zero at centre of earth

then g=0

and w=m(0)

=0

so weight is zero

All of them.

I don't mean to be flip about this, but think about it. If there were any conditions on Earth that weren't conducive to life, we wouldn't be here, would we? So just about any condition you can think of--temperature, pressure, chemistry, you name it--allows us to survive.

The gravitational pull of the moon on Earth's oceans causes tides. When the moon is closest to Earth, during a full or new moon, tides are generally stronger (spring tides). When the moon is at a right angle to the sun, during the first and last quarter moon phases, tides are weaker (neap tides).

Surface temperature is like a fire and your hand, the shorter the distance between your hand and the flame is hotter than when your hand is farther from the flame.

The length of a year is determined by the duration of time that it takes for a planet to make one revolution around it's star, this may also be governed by other factors, such as the three laws of motion, for example; Mercury (the closest planet to the sun) takes 87.969 Earth days to orbit the sun, Earth takes 365 days to orbit the sun, while Neptune happens to take 60,190 days or 164.79 years to orbit the sun.

Somewhere around four or five billion. It's impossible to know for sure -- for one thing, when did the initial ball of rock grow large enough to be considered the Earth? And was the length of a year longer or shorter back then? -- but the solar system is believed to be about 4.6 billion years old.
