(b) Long wave terrestrial radiation

Q.11.Isotherm is:

a) The line joining the places of equal temperature.

b) The incoming short wave radiation.

c) The line joining the places of equal pressure.

e) None.

Answer:

(a) The line joining the places of equal temperature.

Q.12.Conduction refers to:

a) Heating of the atmosphere horizontally

b) Vertical heating of the atmosphere.

c) Heating of the atmosphere coming in contact with the land.

d) Heating process

Answer:

(c) Heating of the atmosphere coming in contact with the land.

Exp. Conduction takes place when two bodies of unequal temperature are in contact with one another, there is a flow of energy from the warmer to the cooler body.

Q.13.Convectional heating is:

a) Lateral heating

b) Vertical heating

c) Heating of the atmosphere by insolation

d) None

Answer:

(b) Vertical heating

Exp. The air in contact with the earth rises vertically on heating in the form of currents.

Q.14.Advection means:

a) Vertical movement of air

b) Horizontal movement of air

c) No movement

d) None

Answer:

(b) Horizontal movement of air.

Exp. Horizontal movement f the air is relatively more important than the vertical movement.

Q.15. Long wave radiation is radiated by:

a) Sun

b) Moon

c) Earth

d) None

Answer:

(c) Earth

Exp. The heat absorbed by the earth during the time is radiated back to the atmosphere in the nights in long wave radiation.

Q.16.What is Albedo.

a) The percentage of visible light reflected by an object.

b) The difference of temperature between two areas.

c) The incoming solar radiation.

d) None

Answer:

(a) The percentage of visible light reflected by an object.

Q.17. For the distribution of temperature which one is not controlling factor:

a) The latitude

b) The altitude

c) Distance from the sun

d) Heat budget of the earth

Answer:

(d) Heat budget of the earth

Exp. Heat budget of the earth is total gain minus total loss of heat received by the earth.
