Molecules are smaller than cells but larger than atoms. They are composed of atoms bonded together to form a distinct structure.
No. Comets are usually a few thousand feet to a few miles wide. An object smaller than a sand grain would not be visible in space.Meteors which enter the earth's atmosphere are often sand grain sized, but the once we can see are usually from pebble sized objects.
yes
Pebbles sink faster than sand grains due to their larger size, weight, and density. The larger surface area of pebbles compared to sand grains experiences less resistance as they sink through the water, allowing them to fall more quickly. Sand grains, being smaller and lighter, have a larger surface area that creates more friction with the water, slowing down their sinking rate.
Yes, a googol is larger than the estimated number of atoms in the observable universe. A googol is 1 followed by 100 zeros, while the estimated number of atoms in the observable universe is around 10^80.
An average grain of sand is about 7-10 times larger than a hydrogen atom in diameter, which corresponds to roughly 7-10 orders of magnitude in size difference.
Yes. Asteroids can be anywhere from the size of a grain of sand to larger than the Earth.
Because of erosion or the water erodes the sand there for shaping it differently.
i really dont know this answer. if i could guess i would say gram.can u answer this ? -> 5 times 1,007,777,779,999,999 + 10 = 50,388,888,900,000,005 . TRUE OR FALSE!!!!!
a grain of sand
No, a small grain of sand typically weighs much less than 1mg. The weight of a grain of sand can vary depending on its size, but on average it is in the range of a few micrograms.
No. Sand grains vary quite a but in size, but for our purposes let us consider a spherical grain of sand composed of quartz that is 1 millimeter in diameter. Such a grain would have a mass of about 0.0014 grams and given the formula of SiO2, with a molar mass of 60 grams per mole, would contain about 4.2*10^19 (42 quintillion) atoms. It is hard to estimate the number of stars in our universe and there do not appear to be any reliable sources. There are about 100 billion galaxies in the known universe and own galaxy contains an estimated 200 billion stars, but it is significantly larger than the average galaxy. If we figure the average galaxy contains about 20 billion stars then we get an estimate of 2.0*10^21 (2 sextillion) stars in the known universe universe, about 50 times the number of atoms in our sand grain.
sugar dissolves, sand don't
Grains of rock larger than sand are called gravel or pebbles.

The clastic grain size between 0.0004-0.0006 mm is classified as silt. Silt particles are fine-grained sedimentary particles that are larger than clay particles and smaller than sand particles.
