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.
How far away is the stratosphere away from the earth?
The stratosphere starts about 10 kilometers (6.2 miles) above the Earth's surface and extends up to about 50 kilometers (31 miles) high.
What pulls everything to the center of the earth?
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.
How many million miles does earth travel in a year?
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.
What is the traveling distance from earth's surface to earth's orbit?
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.
Does the Earths rotation take place on an imaginary line called its axis?
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.
How long will the earths tungsten supply last for?
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.
Where on earth would the weight of a body be zero?
w=mg
gravity is zero at centre of earth
then g=0
and w=m(0)
=0
so weight is zero
What conditions on earth allowed us to survive?
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.
How is the environment different between Mars and Earth?
Mars is smaller than earth with less gravity. It also has a very thin CO2 atmosphere where Earth has a Nitrogen-Oxygen atmosphere that is much thicker. Mars is also very cold while Earth is warm.
- Earth is almost twice the diameter of Mars.
- Nearly 70% of Earth's surface is liquid water, while Mars has none.
- The sun warms the Earth to more the 100oF; on Mars the temperature barely goes above the freezing mark.
- Earth has an atmosphere breathable by humans. Mars has virtually none, and it is composed almost entirely of toxic gases.
- IIRC, Mars is about 1 1/2 time farther from the sun than Earth; and is about 1/2 the size, and 3/4 the density.
- Its surface is largely iron oxide, which gives it its reddish color. There is no liquid water (there is ice at the poles). Because is it has a much thinner atmosphere, and is farther from the sun, it is much colder.
- Astronomers speculate that Mars was once much closer to the sun and was more "earthlike," but gradually moved farther away, resulting in its present state.
How do the moon and tides relate?
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.
How many revolutions around the sun has Earth completed in its entire history?
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.
What gives earth its extraordinary blue colour?
The Earth's atmosphere scatters sunlight in all directions, but it scatters shorter blue wavelengths more effectively than longer red wavelengths. This is known as Rayleigh scattering, and it is why the sky appears blue to our eyes. When we view the Earth from space, this scattered blue light gives our planet its overall blue appearance.
What is happening to earths average tempretature?
Earth's average temperature is increasing due to human activities that release greenhouse gases into the atmosphere, leading to the greenhouse effect. This phenomenon traps heat on Earth, causing global warming and resulting in various climate change effects like rising sea levels, more frequent extreme weather events, and changing wildlife habitats.
What does earths rotation control?
Earth's rotation controls the length of a day, causing the sun to rise and set. It also influences the planet's weather patterns, ocean currents, and the Coriolis effect, which affects winds and ocean circulation. Furthermore, the rotation helps provide the conditions necessary for life to exist on Earth.
What planet is about 10 times as far as earth from the sun?
The closest would probably be Saturn, which has a diameter of around 120 536 km, which is 9.45x Earth's diameter (12 756.2 km). The next closest is Jupiter, with a radius of 142 984 km, or 11.2x Earth's diameter.
Which layer of the earth contains the most silica?
The mantle layer contains the most silica. Silica is a major component of the minerals forming the mantle, such as olivine and pyroxene. This layer lies beneath the Earth's crust and extends to a depth of about 2,900 kilometers.
What is the maximum and minimum distance between Earth and Jupiter?
The maximum distance between Earth and Jupiter is about 601 million kilometers when they are on opposite sides of the Sun (opposition). The minimum distance is around 588 million kilometers when they are on the same side of the Sun (conjunction).
How is the environment on the planet earth like?
The environment on planet Earth is diverse, with various ecosystems that support a wide range of plant and animal life. It faces challenges such as climate change, deforestation, and pollution that impact its delicate balance. Efforts are being made globally to protect and preserve the environment for future generations.
How do you know that the earth is covered with water?
Scientists have used various methods, including satellite observations and direct measurements, to estimate that Earth's surface is approximately 71% covered by water. This calculation takes into account the vast oceans, seas, lakes, rivers, and ice caps that make up Earth's water bodies.
How far is Draco away from Earth?
Draco is a constellation located in the northern sky. It is approximately 309 light-years away from Earth.
It seems like there is a typo in your question. Could you please clarify what you mean by "conitnet"?
