Does the earth grow each year?
short answer no. Longer answer there are micro meteors hitting the earth all the time which even if they burn up in the atmosphere are still adding there mass to the earth, we are sending space probes and other such things in to space which are making the earths mass smaller, and there is radioactive material on the earth which is decaying turning mass in to energy making the earth less massive as well. all these things are negligible in comparison to the mass of the earth so my answer is again no.
Who do earth plates move?
The tectonic plates move because they are floating on magma. They jostle with each other and that's how you get tectonic movement, earthquakes, volcanoes and all that happy stuff.
Which of these spheres do each of the five branches of earth science study?
Which of these spheres do each of the five branches of earth science study?
What force pulls the moon and earth toward each other?
gravity
What percent of the Earth is sodium?
Sodium, magnesium and pottassium are about 2% of the earth EACH!
How much space dust falls on the earth each year?
none
When is earth day annually?
Each year, Earth Day falls on April 22
What topics does earth and space science include?
earth is behaving like space or our space is behaving like earth or some other thing which is force to behaving both like each other.think carefully
When there is a full moon where are the Moon Sun and Earth relative to each other in space?
They are in a line with Earth in the middle.
What happens to each stage in the multistage rocket when it uses up fuel?
The payload (the important stuff) in a multistage rocket is carried in the last stage. The earlier stages are there only for the purpose of boosting the last stage on its way. When each earlier stage is out of fuel, it separates and falls back to Earth.
How does the earth the stay in space?
Both the Sun and the Earth exert gravitational pull on each other; the resulting tension causes the Earth to remain in space rather than crash into the Sun.
What is the effect of sending hard wares into space on the weight of the earth?
Considering the mass of the Earth itself, sending a few tons of mass to the Moon or elsewhere in the solar system is entirely insignificant. Remember that stuff launched into space to Low Earth Orbit - LEO - doesn't count, since like the Mir and Skylab space stations and everything else in LEO, it will crash (or has already crashed) back to Earth when the orbit decays. Also consider that the Earth gains several TONS of mass each day from meteors that fall to Earth, so a few space launches hardly counts at all.
Why the magnets are not attract each other in space?
Magnets behave exactly the same in space as they do on Earth. Who told you that they don't ??
North American landmark which moves backwards?
Niagra Falls due to the erosion of the earth beneath the falls. It moves back about 3 feet each year.
Why does the apple fall on the earth and not vice versa?
The apple falls on the earth because of gravity. It is the force that causes two particles to pull towards each other.
How fast is ameteoriodwhen it enters the earths atmosphere?
Depends whether it is moving in the same direction as the earth, or against it. About 20 km/sec is the average. The fast ones move through space at perhaps 40 km/sec, and the slow ones perhaps half that. The Earth is moving about 18km/sec, so that either adds or subtracts from the meteoroid speed, depending whether it moves with or against Earth's velocity. About 15 000 tons of natural space debris falls on Earth each year.
What will happen if there be frequent visitation of meteorites on earth?
There are frequent visitations of meteorites on Earth! A good Estimate for the total mass of meteoric material that falls on Earth each year is between 37,000-78,000 tons.
