  1. Answer: Most of the small organisms like earth worms, rodents live inside the soil. They usually live in burrows and holes in the soil. These burrows also make spaces available for air to move in and out of the soil. However, when it rains heavily, water fills up all the spaces occupied by the air in the soil
  2. During heavy rains.all the spaces in soil which contained air get filled by rainwater leaving no air in the soil for the earthworms to breathe in. Due to this, the earthworms have to come out of the soil to obtain air for breathing (or respiration) Many animals living in soil dig burrows and holes deep into the soil

Pools of freshwater carried by ocean currents from the central Pacific Ocean's regions of heavy rainfall pile up next to Panama's coast, while the Mediterranean Sea sticks out in the Aquarius maps as a very salty sea. One of the features that stand out most clearly is a large patch of highly saline water across the North Atlantic During heavy rains, the chips soaked up any excess water, then slowly released it into adjacent beds as the soil dried. These paths also made excellent earthworm habitat. But every three or four years, the wood chips break down into soil, leaving low paths prone to vigorous weed populations, so we add new chips During this drought, the pond behind my home dropped about 12 inches in water level, but my water instruction continued just the same.

Answer: (i) The breaks in monsoon are related to the movement of the monsoon trough. For various reasons, the trough and its axis keep on moving northward or southward, which determines the spatial distribution of rainfall. (ii) When the axis of the monsoon trough lies over the plains, rainfall is good in these parts These are large gaping channels that carry large volumes of soil during heavy downpours. Such a type of erosion is called gulley erosion. 5.1.3 Causes of erosion.

Amy Robinson, a member of KCC, belched that [a]n earthworm breathes oxygen by absorbing it through its skin. It likes damp soil, but if the rain is very heavy, the oxygen in the water-logged soil may run out. Then the worm has to come up into the air to breathe. Worms do not have lungs like humans and other animals have In plants, respiration occurs during the day as well as during the night. During the day, oxygen produced during photosynthesis is used for respiration and the extra amount of oxygen is given out through the stomata. The roots of plants take up oxygen from the air present between the roots and soil particles Soil is alive and a key enabler of life on land and in the air. The images of soil and of microbes need to change to reflect the benefits they bestow upon us and the rest of the biosphere, to promote humankind to embrace the policies and actions needed to repair, restore and maintain in good health soils that are currently unhealthy, and to attain soil sustainability The text book of Lakhmir Singh And Manjit Kaur for Class 10 Biology gives the students a detailed picture about each and every chapter.

It is closely linked to land. Landforms determine the type of soil. Soil is made up of organic matter, minerals and weathered rocks found on the earth. This happens through the process of weathering Soil aggregation and aggregate stability are not a result of mechanical processes (running a plow through the soil) but chemical and biological processes. Well-aggregated soils are crumbly and open, allowing water to easily infiltrate rather than run off during heavy rain events. They will have the texture of cottage cheese A full half of an ideal soil is made up of WATER AND AIR which all of the living organisms in your soil and the plants you want to grow need to sustain their lives. This is why COMPACTION is something we want to avoid. Soil becomes compacted, and the pockets of air and water disappear, when we step on soil unnecessarily and when we use excessive tillage Why Salt? Ice forms when the­ temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius), and that includes ice on roadways. Road salt works by lowering the freezing point of water via a process called freezing point depression.The freezing point of the water is lowered once the salt is added, so it the salt makes it more difficult for water to freeze
