Distunguish Between Things In Weather

Question 1

Distinguish between dew and frost

Answer 1

Dew are tiny drops of water formed when water vapour condenses on the ground or cool surfaced when the temp is not below 0°C

It is not harmful to crops

Frost is when condensation takes place below 0°C tiny crystals of ice firm on plants crops and groung

They cause damage to cultivated crops and trees

Question 2

Distinguishes between fog and mist

Answer 2

A dense mist is called a fog. It is denser than mist and dangerous as it reduces visibility

Droplets if the atmosphere suspend close to the surface if the earth. It is lighter than fig and not as dangerous

Question 3

Distinguishes warm and cold ocean current

Answer 3

Warm ocean currents move from lower latitudes to higher latitudes they generally make the coastal areas un the gifher latitudes warmer than usual

Cold ocean currents mive from higher latitudes to lower latitudes they lower the temperature of the places in the lower latitudes

Question 4

Distinguish absolute and relative humidity

Answer 4

Absolute humidity is the amount of moisture present in the air it is expressed as gram cubic metre in the air.

It us the relationship between the amount of vapour in the air at any temperature and the maximum amount of vapour in the air can hold at the temperature it is expressed as %

Question 5

Maritime and continental climate

Answer 5

Olaces that are influenced by the sea us called maritime climate
The sea has a moderating influence on temperature and places near the sae have mild climate change

Places that have a great distance from the influence of the sea is said to have continental climate

Question 6

Distinguish weather and climate

Answer 6

Weather is the condition ir state if the atmosphere if a place over a short period of time it is never static and ever changing thus cannot be generalized

Climate is the average of the atmospheric conditions of a large area such as a country over a long period of time ut does not change hence can be generalized

Question 7

D isotherm

Answer 7

Places experiencing the same temperature at a given time are connected with a line this line is known as the isotherm

Question 8

D isohyets

Answer 8

Places recieving the same amount if rainfall over a period of time are connected with a line

Question 9

D humidity

Answer 9

The amount of moisture or water vapour in the air is called humidity

Question 10

Gr india has tropical monsoon climate

Answer 10

The temperatures are high in India for most of the year and the country recieves rainfall during the monsoon season

Question 11

Gr italy experiences Mediterranean climate

Answer 11

It lies in the med regions hence experiences warm dry summers followed by cool wer winters

Question 12

Name the elements of climate

Answer 12

Temperature, pressure, humidity, precipitation, wind direction and speed, clouds cover and sunshine

Question 13

What is evaporation

Answer 13

It is the process in which water changes into vapour. There is a change in the physical state. Heat is absorbed during this process. It can occur when the airs dry at any temperature

Question 14

What is condensation

Answer 14

It us the process by which vapour changes into water. There is a change in the physical state. Heat us released during the process . It occures only when the air is saturated. Clouds mists fog dew arr forms of condensation

Question 15

What is precipitation?

Answer 15

It is the process by which water falls down on the earths surface. There is ni change in its physical state. It occures under different conditions. Rain drizzle snow and hail are forms of precipitation

Question 16

Describe currus clouds

Answer 16

These are feathery fibouris clouds which form at very high levels from 5km to 10km they consist of tiny crystals of ice and look like wips of cotton floating in the sky

Question 17

Describe cumulus clouds

Answer 17

They are cauliflower shaped clouds that have great vertical height and flat base
They cause rainfall with lighting and thunder and are hsually white or grey

Question 18

Stratus clouds

Answer 18

These are sheet like clouds which soread iver the while sky they are from low levels like 2km they are grey and dull

Question 19

Describe nimbus clouds

Answer 19

Tet are real rain clouds heavy thick black soread in layers they cause continuous rain and snow

Question 20

What is rain

Answer 20

It is the most commin form of precipitation

Question 21

What us drizzle

Answer 21

Light drain drops that a smaller is called drizzle

Question 22

What is snow

Answer 22

Feathery flakes if frozen moisture fall in the surface of the earth when temperature ramains below freezing point

Question 23

What is sleet

Answer 23

It is a mixture of rain and snow

Question 24

What is hail

Answer 24

Frozen raindrops from ice pallets and fall as hail it is the most destructive form if precipitation
