Earth has primarily its at the beginning of rock along decay animal and plant if you can imagine long lines or periods of time when mass of the wholesale crumble rock and demolition. Heating, the action of water and friction were largely responsible for this. Friction here means rubbing and rock mass crushing against the rock mass. Think of boulders, chaos perfect colonization in collision, scratching against each other. What would the result be? Well, of course to all them could work that happened: pieces of rock has been used a lot of heat is produced, pieces of rock was pressed with the masses of rock new form, some parts are dissolved in water. Why feel stress and tension of almost everything. You can?
Then there are also large temperature changes. For the first time, everything was heated at high temperature and then gradually it was cool. Just think rust cracking, upheaval, such changes must have caused! You know some of the effects of the sudden freeze in winter and thaws. But examples only burst water pipes, and coffee broken, it's like nothing of what is happening in the world in those days. Water and gases in the atmosphere has helped on this work in ruins.
All this friction, action action, we call mechanics, it is easy enough to understand how the sand has been formed. It is a land of sandy divisions of large land. The sea are large masses of clean sand. If nothing but potato broken rock masses, then it would be really very poor and unproductive. But the first forms of animal and plant life used was part of the rock mass and a solo for best result. Soil spoke of sandy soils how mixed with sand, sometimes laugh, sometimes often waste material or humus vegetables and animals.
Clay brings us reason for another class of soils of clay soils. It turns out that some parts of the masses of rock was dissolved when water on them and heating was pretty and ample. This solution took place, mainly because there is no on-air light gas called carbon dioxide or carbonic acid gas. This gas attacks and modify certain substances in the rocks. Sometimes, you can see large rocks with portions of boring look as if they had been eaten away. Carbonic acid was done. A changed this edible portion on the other hand, we call on clay. A change like this is not mechanically but chemistry. The difference between the two types of change is simply this: in the case of sand, where a mechanical change now, you still have what began you with, except the size of the mass is lower. You started with a big rock and ends with a bit of sand particles. But you had no other type of rock in the late mechanical Action can be illustrated with a piece of real sugar. Let the sugar represents a large rock mass. Break down sugar and even the slightest bit is sugar. This is how the rock mass. But in the case of a change in chemistry you start with one thing and end with another. You started with a big rock mass which had partly amended by acid acting on it becomes totally different that we call the clay. Then a chemist, change a certain something first and at the end, we have completely different things. Silty soils are called Lama soils due to the amount of water used in its formation.
The third type of Earth as we people need to deal with farm is on the ground lime. Remember to think of land from the point of view. Of course, this land generally composed of limestone. As soon as something is mentioned, as we know, nothing comes another, as we are all ignorant. And so follows a whole chain of questions. Now say you probably in themselves, as the limestone was formed?
In an age of ages there are shapes of animals and plants less recalls water particles with Cal. CAL form skeletons or houses themselves as larger animals protection. Coral is representative of this class skeleton forming the animal.
As the skeleton of dead animals has remained. Large masses of living matter pressed form after age, limestone. Some limestones are still underway, exfoliation training is still visible. Marble, limestone, another is something of crystalline in nature. Another well known limestone is chalk. Perhaps you would like to know a way to be always able to say limestone. Drop a little of this acid in some Cal. see how the bubbles and fizzles. Then drop some chalk and marble also. Meet the same stream. How cal should be these three structures. We shouldn't have to buy a special acid for this task, the household even acid like vinegar would cause the same result.
Then these are the three types of land that the farmer has to do and how we want to understand. Because you can get to know your garden soil considering as a teacher in a classroom study.
