The observation, identification, description, experimental investigation, and theoretical explanation of phenomena is all part of science. Nothing is immune to the scientific process: from charm quarks that haven't existed naturally since the beginning of time to Pluto, recently demoted from planet to dwarf planet. Questions on knowledge about the material and physical aspects of our world are asked and answered here.

Because sunlight is absorbed mostly by solid objects (not the gasses of the atmosphere), so the ground heats up, and warms the air adjacent to it.

If you mean living processes, then the answer is Sunlight. If you mean geological processes, then the answer is decay (nuclear fission) of radioactive isotopes in the Earth's core and Sunlight. If you mean tidal processes, then the answer is kinetic (rotational) energy transfer.

You don't need a "system" if you're small enough so that the function can be distributed throughout your entire body - as are all single celled organisms. But it works all the way up through jelly fish.

This is impossible to answer unless you know what substance we are talking about. The same mass of different substances occupies different amounts of space. The mass of 1 centimetre cubed of a substance is called its density. Temperature also matters as most substances become less dense when you hea…

Gravity. Whenever the planet got hot enough to melt everything (either/or) because of massive impacts or heat from radioactives, then the denser materials settled towards the center, with lighter stuff floating over the center.

You can demonstrate this problem quite easily by removing the peel from an orange in one or two pieces. If you try to lay it flat you'll find you have to make lots of cuts in it, and it still doesn't work well. If you draw a map like this, parts that should be connected are not. If you try to draw t…

You could answer that in many ways but the most obvious is into physics and chemistry. Physics deals with energy and forces amongst other things, and concentrates on what happens to a substance. Chemistry deals with the nature of the substance and what other substances you can turn it into.

The clue is in the name. Plastic means 'shapeable'. When they are first made these substances are soft enough to be squeezed out like toothpaste, flow into moulds with intricate shapes, rolled into thin sheets and be stamped into shapes like trays. When they cool they set in the new shape. Some set …

When two amino acids combine to form a dipeptide, the small molecule eliminated is water, hence the name condensation reaction. However, you can also make dipeptides from amino acid derivatives such as acyl chlorides, in which case the molecule eliminated is different (hydrogen chloride in the case …

Igneous rocks are usually classified by their chemical composition (acidic or basic), and by whether they formed underground (intrusive, characterised by large mineral crystals) or on the surface (extrusive, made of tiny, microscopic crystals). For instance, basalt is a basic, extrusive rock, and gr…

This is thought to be because NCl3 hydrolysis is initiated by a water molecule, acting as a nucleophile, attacking a chlorine. The N - Cl bond is only very slightly polar, with the chlorine as the slightly positive end. The N - F bond on the other hand is much more polar, and in the opposite directi…
