There is a finite number of the basic element of life forms on earth – the atomic particle-. are there enough available for the production of the estimated 4 billion more humans over the next eighty years, together with all their support necessities- food, clothing . housing, transport, education,warfare, etc without the extinction of other life forms of earth?

Yes, in that way Earth loses a little bit of mass.

How about the satellites made and sent out there to space and never comeback ???

Yes, very true

what about the fact that its emitting gravitational waves which is another reason for losing mass?

Does molten lava weigh the same when it cools and forms land after a volcanic eruption? My thoughts would suggest as the earth cools, it shrinks and becomes more dense. It’s why the plates don’t fit together anymore and create earthquakes and mountains in their adjustment process. Earth was bigger than it is now, but less dense. Civilization adds density. Our moon doesn’t rotate on its axis and a heavier earth would create even greater gravitational pull. Just like Jupiter’s moons, someday our moon will succumb to accretion.

Earth is an approximation of a closed system contained between the Magnetosphere, approx. 100 kms above the earths surface, and the Inner core centre approx 6378 kms below the Earth’s surface. All the matter that has built all life forms in all of earth’s history is still contained within this system. All future life forms, whether animal, aviarial,insectival, botanical, bacterial, viral, robotic, electronic or what-so-ever will consist of matter that has already been part of millions of past life forms. Only minor amounts of virgin matter comes into the Earth system. Estimates of cosmic dust entering Earth’s atmosphere range between 5 and 500 tonnes per day. This is offset by somwhere near the same amount of Hydrogen and Helium gasses leaving, as the only elements light enough to escape gravity without the use of large amounts of energy.

Life exists in the Biosphere, a narrow layer encircling the molten inner core, the solid outer core and the mantle from 35 kms below the Earth’s surface to the troposphere 11 kms above Earth’s surface. The materials for the development, sustainment and replacement of all Earth’s life forms are contained within this Biosphere, 0.0007% of the total volume of the Earth system. Except for volcanic activity spreading rich plant nutrients and long term weathering, increases in any life form on earth are dependent on recycling material within the Biosphere.
The Earth is basically made of atomic particles. The basis of all matter contained within the Earth’s system is the Atomic Particle that forms the atom that builds the molecule that make up cells that organise every living entity. Non- living matter also is based on atomic particles and is the greatest percentage of the Earth’s mass.. The total number of atomic particles within the planet and its atmosphere is incomprehensible, possibly incalculable but finite.
An increase in the total number of any life form is dependent on the supply of atomic particles being available from within the Biosphere

The toopic of bio matter (plants, trees, animals, people) growth having an effect on overall earth mass, keeps being brought up, The answer is no, there is no increase in mass, in fact, the more LIFE you have, the greater the decrease in overall mass. I was 8 pounds at birth, and 218 now, I have consumed maybe 50,000 pounds of food, and 100,000 pounds of fluid, and can not even begin to estimate how much gas (oxygen, Co2, argon, etc.), yet in turn, I also expell a variety of waste products, fecal, urine, gaseous, sweat, tears, blood, which cancels out all but6 the 210 pounds I have gained since birth. Everything I consumed to grow was already here, everything I have expelled is still here.

however, the consumption of resources requires energy, and the expelling of waste consumes energy, the loss is insignificant over my lifetime, yet, I am a carbon based life form, and experiencing radioactive decay like everything else…its called entropy.

Not necessarily. It depends on the orientation of material impacting Earth. Since it comes from all sorts of directions, the angular velocity wouldn’t increase.

1.if the mass of the earth is increased then angular velocity also inceased. is it true?

i. Suppose that if the weight of the Earth is increased 10 to 15% from their actual weight,what kind of effect will come on the rotation and revolution of earth.

ii. When the earth formed their rotation and the revolution will be as it is today

well you’re partly right, but you’re missing the fact that because it sends energy in the form of photons, the objects in subject on earth would gain an extremely small amount of mass because of that energy. We know that when objects gain energy and mass simultaneously, because of Einsteins iconic equation, E=mc^2. This reply is almost a year late, so I probably shouldn’t even post it but whatever
