The human brain develops from the tip of a 3-millimeter-long neural tube. At three to four weeks after conception, the neural groove closes into a tube, and three distinct regions—a hindbrain, midbrain, and forebrain—begin to take form.

The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the ****. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and ****. The liver, pancreas, and gallbladder are the solid organs of the digestive system.

How is soil made

Posted by Avijit Goswami 3 years, 5 months ago

CBSE > Class 04 > Science

3 answers

Sia ? 3 years, 5 months ago

Soil is the thin layer of material covering the earth’s surface and is formed from the weathering of rocks. It is made up mainly of mineral particles, organic materials, air, water and living organisms—all of which interact slowly yet constantly.

Most plants get their nutrients from the soil and they are the main source of food for humans, animals and birds. Therefore, most living things on land depend on soil for their existence.

Soil is a valuable resource that needs to be carefully managed as it is easily damaged, washed or blown away. If we understand soil and manage it properly, we will avoid destroying one of the essential building blocks of our environment and our food security.
