What is a naturally occurring aggregate of minerals?
A rock is a naturally occurring aggregate of minerals formed through geological processes such as cooling and solidification of magma or metamorphism of existing rocks. Rocks are classified based on their mineral composition and texture.
Why does gold occur native whereas zinc doesn't?
Gold occurs naturally because it is a stable molecular element - it doesn't react with other elements well. Zinc is more reactive than gold so it is difficult to find JUST zinc buried in the ground, instead you get something like zinc oxide and other pollutants which you have to refine.
What is the different between a rock and mineral?
A rock is composed of combinations of minerals, each mineral having its own chemical formula and crystalline structure. Minerals are composed of an element or combination of elements. Granite, for instance, is an intrusive igneous rock composed ofthe minerals quartz, feldspar, mica, hornblende, and other combinations or ratios of minerals.A mineral is a naturally-occurring inorganic (there are some exceptions to this) crystalline solid (though mercury is regarded as a mineral) with a specific chemical composition and a characteristic internal regular geometric arrangement of atoms, sometimes expressed as natural crystal faces.A rock is an aggregate of one (such as quartzite) or more (such as granite) mineral particles formed through either crystallization of molten magma (igneous rocks), settling of particles (sedimentary rocks), or reheating and pressure applied to pre-existing rocks (metamorphic rocks), with no set chemical composition or atomic structure.
Research on the manufacture and the use of organic and inorganic fertilizers and how these affect the environment?
Organic fertilizers are manufactured using only naturally existing elements, while inorganic fertilizers use chemical compounds that contain the same types of minerals and nutrients as organic fertilizers. An organic fertilizer might use fish emulsions to add certain nutrients to the soil, while an inorganic fertilizer might use a man made acid based compound to fulfill the same need as the fish emulsions. Organic fertilizers are often times absorbed much more easily into the environment with little side effects, although any runoff of nutrient rich water can affect a watershed's territory. The main problem with inorganic fertilizers is that they use "steroid" like compounds to maintain faster vegetative and flowering growth cycles.
What m described rocks that were formed when existing rocks were heated or squashed?
Metamorphic rock. This can naturally form an existing Sedimentary, Igneous or Metamorphic rock due to exposure to heat and/or pressure.
Are all elements naturally existing?
No
What is a mineral and how is it formed?
A mineral is a naturally occurring inorganic solid with a crystalline structure and a definite chemical formula. Most minerals are formed from the cooling or evaporation of solutions containing the elements necessary for mineral formation.
What you all of the living and nonliving organisms existing in an enviromment is called and what?
ecosystem i think
Did methuselah die of natural causes?
Yes, never existing is a naturally occurring illness. Yes, never existing is a naturally occurring illness.
Are most elements man made or natural?
All the existing elements are natural the man made elements are rare and have a very short life.
What is another name for living and nonliving?
dead and alive existing and nonexisting life and death here and gone
New cells form when already-existing cells divide means that?
new cells can be formed from nonliving matter
Elements that are made by fusing existing elements with fast-moving particles are called what?
Elements that are made by fusing existing elements with fast-moving particles are called transuranium elements or synthetic elements. These elements are usually created in a laboratory setting through nuclear reactions and are typically unstable and radioactive.
Who originated theory of biogenesis?
The Law of Biogenesis, attributed to Louis Pasteur, states that life arises from pre-existing life, not from nonliving material.
Why is the sun nonliving?
Because it has no existing life on it. If any living thing were to land on the Sun, it would burn due to very high temperature.
Why is sun nonliving?
Because it has no existing life on it. If any living thing were to land on the Sun, it would burn due to very high temperature.
Why was Mendeleev's periodic table was useful?
Because it organized all of the existing elements and helped scientist discover more elements.
