Role of soil in agriculture and its formation process.
Soil is usually the upper layer of Earth in which the growth of most plants takes place. Soil is characterized as a ‘hot bed’ which is a mixture of minerals, air, water, insects, worms, and billions of bacteria.
Soil is the most important aspect of agriculture and also the main source of nutrients needed for the growth of plants which feed us. It takes approximately 500 years to generate 2.5 centimeters of soil in a dried up or parched area.
Answer: His arms muscles work in pairs so that one contracts while the other relaxes as he climbs up.
Explanation: when we exercise one muscle, there is usually another muscle that isn't the target of the exercise but it helps us maintain the form by doing the opposite movement. For example, when we do a bicep curl, the muscle that we are working is the biceps, and it contracts, but at the same time, the triceps relaxes, this is called antagonist muscles. The same thing happens when a rock climber climbs up the rock wall, the biceps contract as he pulls up and the triceps relax at the same time.
