Distunguish Between Things In Weather Flashcards
Distinguish between dew and frost
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
Distinguishes between fog and mist
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
Distinguishes warm and cold ocean current
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
Distinguish absolute and relative humidity
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 %
Maritime and continental climate
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
Distinguish weather and climate
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
D isotherm
Places experiencing the same temperature at a given time are connected with a line this line is known as the isotherm
D isohyets
Places recieving the same amount if rainfall over a period of time are connected with a line
D humidity
The amount of moisture or water vapour in the air is called humidity
Gr india has tropical monsoon climate
The temperatures are high in India for most of the year and the country recieves rainfall during the monsoon season
Gr italy experiences Mediterranean climate
It lies in the med regions hence experiences warm dry summers followed by cool wer winters
Name the elements of climate
Temperature, pressure, humidity, precipitation, wind direction and speed, clouds cover and sunshine
What is evaporation
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
What is condensation
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
What is precipitation?
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
Describe currus clouds
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
Describe cumulus clouds
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
Stratus clouds
These are sheet like clouds which soread iver the while sky they are from low levels like 2km they are grey and dull
Describe nimbus clouds
Tet are real rain clouds heavy thick black soread in layers they cause continuous rain and snow
What is rain
It is the most commin form of precipitation
What us drizzle
Light drain drops that a smaller is called drizzle
What is snow
Feathery flakes if frozen moisture fall in the surface of the earth when temperature ramains below freezing point
What is sleet
It is a mixture of rain and snow
What is hail
Frozen raindrops from ice pallets and fall as hail it is the most destructive form if precipitation
