Three main types of environmental zones are recognized in the ocean basin (i) Littoral zone sea floor in the region of continental shelf. This is the area close to the shore and extending out to edge of the continental shelf. The intertidal zone of beach and estuaries are also part of littoral zone. (ii) Benthonic zone sea floor along continental slope, aphetic and abyssal zones (iii) Pelagic zone water of the ocean. It is nutrient poor zone.

The soil which is transported by wind is known as
1 Colluvial
2 Eolian
3 Aluvial
4 Glacial soil
Explanation:
The soil transported by wind is known as eolian soil. - Eolian - Trasnported by wind - Colluvial - Transported by gravity - Alluvial - Transported by running water - Glacial soil - Transported by glaciers

Which one soil type and its composition is considered best for growth and development of common vegetation?
1 Loamy and clay soil
2 Loamy soil (25-36\% field capacity) a mixture of clay and sand
3 Black and clay soil
4 Both loamy soil and sandy soil
Explanation:
Loamy soil is a mixture of clay ( $30 \%$ ) and sand $(70 \%)$ and contain $25-35$ field capacity, i.e. water retaing capacity. This type of soil is considered best for crops and common vegetation. Water infiltration, and adequate aeration facilitate good penetration of root in loamy soil.

The soil with poorest water holding capacity is
1 clay
2 loam
3 sandy
4 None of these
Explanation:
Exp: Water holding capacity is the extent to which the soil can hold capillary water against gravity. It is defined as the amount of water retained by unit weight of dry soil, when immersed in water under standardized condition sandy soil has poorest water holding capacity. Clay soil- Clay-rich soil has the largest pore space, hence the greatest total water holding capacity. Loam- Loam soil should consist of equal part of all three soil type. This combination of soil type creates the perfect soil texture for plant growth.
