Answer:
A river forms from water moving from a higher elevation to a lower elevation, all due to gravity. When rain falls on the land, it either seeps into the ground or becomes runoff, which flows downhill into rivers and lakes, on its journey towards the seas.

Answer:
These areas are called as Biological Hotspots
Explanation:
- Most of the species near to extinction and vulnerable are those which are kept in bio hotspots, these hotspots er conservation areas and hence limited in numbers.
- These hotspots check the population of the species from being jeopardized in the future. These tend t provide a reserve or facility to keep endemic species in natural surroundings in a protective environment under the scanner of rangers and wildlife protectionists.
- Forests are themselves a type of reserve a protected area that helps the growth and development of these species on land and water and also check there reproductive capacity
- Maintenance of these hotspots is a must for a nation to preserve its wild heritage and keep balance with the biodiversity of the region.
Answer:
Option (1)
Explanation:
Clay is the most porous but least permeable rock.
The porosity is defined as the property of the rock that allows the water to store in its pore spaces. In simple words, it is the measure of the pore spaces that are present in the rock. Whereas the permeability is the property that allows the fluid to pass through the cracks of the rocks and mixing up with the groundwater.
So, in the case of clay, the inter-granular spaces (pore spaces) between the rocks help in trapping the water in them, but they do not allow the water to transmit and get mix up with the groundwater. So, they are the best example of porous rocks.
Hence, the correct answer is option (1).
