24/4/24 latitudes longitudes and atmospheres Flashcards
Which latitude is the biggest Circle?
Equator
The lines of the latitudes are
Parallel to each other
Distance between the two latitudes is
111 km
What is latitude?
Latitudes help you in getting the information about different temperature zones over earth
What is the area between two latitudes called?
Zone
The latitude about the equator are called northern hemisphere latitudes
Indicated by N
Latitudes forms a
A complete circle over earth
What is the total number of degrees in latitude?
181 including the equator
What is called the Tropic of cancer?
It is the latitude formed at 23.5° northern hemisphere
What is called Tropic of Capricorn?
What is the latitude formed at 23.5° South
What is tropical zone?
The zone between the Tropic of Cancer and Tropic of Capricorn is called tropical zone because this zone receives immense amount of it throughout the year. That’s why any country or part lying in the zone will never have winter that’s why this zone is called tropical zone
What is called a frigid zone
There is zone between 66.5°, North Arctic Circle and 90° north S zone between 66.5°, South Antarctic Circle and 90° South have extremely cold temperatures. That’s why it is called frigid zone
What is the temperate zone?
Don’t lies between the 23.5° North and 66.5° North Artic circle same way temperate zone lies between 23.5°, South Tropic of Capricorn and 66.5° Antarctic Circle reason for receive extreme season
What is called and latitude?
Latitude is the distance on the Earth surface north or South of the equator expressed in angular measurement is 0° and equal to 90°. In simple words latitudes are the parallel lines running from east to west or vice versa.
What is called Tropic of Cancer?
The line joining both the points of 23.5° in the northern hemisphere is called the Tropic of Cancer.
The countries which lie on the Tropic of Cancer
Mexico, Bahamas, Mauritania western Sahara Mali Algeria, Niger, Libya, Egypt, Saudi Arabia, UAE Oman India, Bangladesh, Myanmar, China, Taiwan
What are the two North American countries Tropic of Cancer?
Mexico and Bahamas
what is called the Tropic of Capricorn
The line joining both the finals of 23.5° in the Southern hemisphere is called Tropic of Capricorn.
What are the countries present in the Tropic of Capricorn?
Chile Argentina, Paraguay Brazil, Namibia, Botswana South Africa, Mozambique, Madagascar, Australia, and French Polynesia
What is equator?
A line notionally drawn on this earth equal distance from the polls, dividing the Earth into northern and Southern hemispheres, and constituting the parallel of latitude 0°
The countries falling on the equator or
Ecuador, Colombia, Brazil, São Tomé and Príncipe, Gabon Republic of Congo, democratic republic of Congo, Uganda, Kenya, Somalia, Maldives, Indonesia, Kiribati
What are the seven countries penetrated by the Artic circle?
USA, Canada, Greenland, Norway, Sweden and Finland Russia
What is the longitude?
Longitudes are the imaginary lines which ran from poles to poles. These are not the parallel lines. The distance between the two longitude increases as one move from poles to equator. The distance between two longitudes is maximum at equator and minimum at the poles.
What is called the greenwich line?
 0° land line is called the prime meridian . Greenwich line as it passes for the greenwich line of England. This line is used for a time calculation of the various countries over the globe.
Longitude lines don’t form a complete circle the form here
Semicircle
The area between the two longitudes is called
Gore
Distance between the two longitude at polls
0
Distance between two longitudes at equator
111.32km
The prime meridian divides the globe into two halves
Eastern hemisphere and western hemisphere
The importance of longitudinal lines is to get
Time evaluated
15° in longitude is equal to
One hour
1° in latitude is equal to
Four minutes
The time increases from
West to east
Time decreases from
Eastern hemisphere to western hemisphere
What is the atmosphere?
Atmosphere is the combination of various gases. The name atmosphere is made up from the greek word Atmos which means air
Atmosphere contains
78.09% nitrogen, 20.95, oxygen .93 argon and 0.0 39% of carbon dioxide
Troposphere
The lowest layer of the atmosphere, including human life
After every 165 m in troposphere, the temperature decreases to
1 Degrees centigrade
What is the thickness of troposphere above the poles
8 km thick
What is the thickness of troposphere above the equator?
18 km thick
Where is the stratosphere situated?
50 km above the surface of the Earth top
What separates the troposphere and stratosphere
Tropopause and its thickness is 1.5 km.
Which layer of the atmosphere is called the Earth’s protective shield
Stratosphere due to the presence of ozone gas which observe the sun’s ultraviolet rays. The temperature also increases in this layer of the atmosphere with the increasing height.
Which layer of the atmosphere is suitable for flying in aeroplane?
Stratosphere
What is called the coldest layer of the atmosphere
Mesosphere
Where is Mesosphere located
Mesosphere is situated at the height of 80 km from the surface of the Earth. In this layer, the temperature decreases with increase in height and can reach up to minus hundred degrees centigrade.
Where is Ionosphere situated?
Ionosphere sphere is situated at the height of 80 to 690 km
Which layer of the atmosphere helps in the reflection of radio waves
Ionosphere
What is the hottest layer of the atmosphere?
Thermosphere
What is the temperature range of thermosphere?
1000 to 1500°C
Where is the international space station and hubble telescope located?
Thermosphere
Which is the topmost layer of the atmosphere
Exosphere it starts after 640 km after the surface of the Earth
What are the gas is present in the exosphere?
Hydrogen and helium gas
Exosphere is also known as the
Outer space
where is the stratosphere located
stratosphere is located at 50 km above the earths top
what sepates the trophosphere and stratosphere
tropopause
thickness of tropopause is
1.5 km
ozone gas is present in which layer
stratosphere
the ideal condition of flying an aircraft is found in the
stratosphere
92% of the atmosphere exists in
troposhpere
the thickness of the troposphere is
8km thickness above poles and 18 km thickness above equators
where is the mesosphere located
mesosphere is located above 80km from the surface of the earth
