12
Q

How does albedo affect the climate?

A

the higher (lower) the albedo of the surface, the lesser (higher) amount outgoing radiation is observed.

14
Q

Why does vegetation has low albedo?

A

it is due to absorption of incoming radiation and rough surfaces.

15
Q

It affects the albedo of the area by cutting trees and pollution and causes more severe thunderstorms, increased cloud cover, & higher temperatures.

A

Q

TOPOGRAPHY

A

the arrangement of the natural and artificial physical

features of an area.

17
Q

modifies an area’s weather and climate thru the direction of the wind which dictates the amount of precipitation.

A

OROGRAPHIC EFFECT

18
Q

created due to difference of specific heat capacity of

land and water (sea).

A

LAND/SEA BREEZE

19
Q

Occurs at night and offshore winds are also known as?

A

Land Breeze

20
Q

Occurs during daytime and onshore winds are also known as?

A

Sea Breeze

21
Q

It is the energy needed to change the temperature of an object by 1 °C.

A

specific heat (c)

22
Q

What is the meaning of lower c

A

It means faster heat transfer and cooling.

23
Q

It is a type of weather condition derived from a matured vertical cloud known as cumulonimbus and can be formed and dissipate in <= 30 minutes.

A

Thunderstorm
