Answer:
Explanation:
1. Soil is called renewable resources because it can be use even when it not have nutrients.
2. Igneous rocks are primary Rock because they are not mainly use.
4.Yes, Sedimentary rocks tell us about our evolution of life because they are formed millions of years ago.
3 and 5 not remember.
Explanation:
1 ) Soil is the grainy material in Earth's crust on which plants grow. It is comprised of both organic and inorganic material. The creation of soil is dependent on the geological processes of weathering and transportation of weathered material.
2) As igneous rocks are formed from magma and begin the rock cycle, they are called primary rocks.
Explanation:
Igneous rocks are created from the cooling of molten magma/lava. All other rocks are derived from them, which is why you will also find them referred to as parent rocks on occasion.
3) Intrusive, or plutonic, igneous rock forms when magma is trapped deep inside the Earth. Great globs of molten rock rise toward the surface. Some of the magma may feed volcanoes on the Earth's surface, but most remains trapped below, where it cools very slowly over many thousands or millions of years until it solidifies. Slow cooling means the individual mineral grains have a very long time to grow, so they grow to a relatively large size. Intrusive rocks have a coarse grained texture.
4) Sedimentary rocks are ones that have formed by the weathering of preexisting rocks (chemical and mechanical breaking up of sedimentary, igneous, or metamorphic rocks) to form sediments that are transported (moved by wind, rivers, ice, or other means), and deposited (when the wind or river, for example, becomes too slow to carry the sediment further and it settles out), and then lithified (minerals, often deposited out of pore water, cement the sediment grains together to make a new rock). Sedimentary rocks tell us about past environments at Earth's surface. Because of this, they are the primary story-tellers of past climate, life, and major events at Earth's surface. Each type of environment has particular processes that occur in it that cause a particular type of sediment to be deposited there. This can be illustrated by a simple experiment. Think about putting a pile of mud, sand, and gravel in a pile on one side of a plastic basin, and putting water at the other side. Gently slosh the water against the "shoreline" of the mud, sand and gravel (making waves). Do this for a while. What happens? (answers, est2a4.html). This simple experiment illustrates the key way that many sedimentary rocks tell stories: The size of particles reveals the energy present in the environment of deposition. Think of this other example: Fast mountain rivers have gravel in them because smaller sand and mud is washed away. Slow meandering rivers often have mud in them because the slow water allows the mud (clay and silt) to settle out. Water, ice, and wind each carry sediment in a different way, with water and wind sorting the sediment out by size according to the speed (energy) of the water or wind, whereas ice carries sediment indescriminately, resulting in an unsorted mixture of gravel, sand, and mud which we call glacial till. Finding an unsorted sediment or rock can therefore be a clue to a long-vanished glacier. Finding shale (made of tiny clay and silt particles, try scraping them off with a knife to see the powder that forms) is a clue to a body of very quiet water with little movement, like a deep lake or an ocean distant from the waves.
5) Rust, for example, is iron oxide. When rocks, particularly those with iron in them, are exposed to air and water, the iron undergoes oxidation, which can weaken the rocks and make them crumble.
