[#642] Upper layer of water in a single body of water is known as
Correct Answer
(B) Epilimnion
Explanation
Solution: Upper layer of water in a single body of water is known as Epilimnion.
[#643] The lower limit of water availability in soil is known as
Correct Answer
(D) Wilting point
Explanation
Solution: The permanent wilting point is considered as the lower limit of plant-available soil water and depends upon both plant and soil characteristics. The quantity of water held by the soil between the field capacity and permanent wilting point is considered as the plant-available water.
[#644] The top layer of the lake is called as
Correct Answer
(B) Epilimnion
Explanation
Solution: Lake stratification is the separation of lakes into three layers: Epilimnion: the top of the lake. Metalimnion (or thermocline): the middle layer, which may change depth throughout the day. Hypolimnion: the bottom layer.
[#645] The atmospheric layer in which we live is called the:
Correct Answer
(A) Troposphere
