→Activity No 1- Using Marble to study Latitudes
*'''Process'''
*'''Process'''
#Demonstrate Latitude on the Marble atlas. Move the earth from west to east to simulate the rotation of the earth. Move the Earth 'top down' and 'bottom up' also upside down to show Arctic Circle in the bottom. Explain 'north' and 'south' are only conventions and not 'up' and 'down'

#Show the 'Precipitation (July) map? Is there any pattern in the rain heavy zones? Does it depend on the Latitudes?

##(tip - Is there more rain in the northern hemisphere than southern hemisphere? Within the northern hemisphere, is it heavier in some parts, are these related to the latitude of that place?)
##(tip - Is there more rain in the northern hemisphere than southern hemisphere? Within the northern hemisphere, is it heavier in some parts, are these related to the latitude of that place?)
##Why is the rain heavy in the south west coastal part of India (including coastal Karnataka)? Why is there a vertical strip where there is very less rain?

##While North India around tropic of cancer has good rainfall, why is the same tropic of cancer region in Africa without any rain at all? Tip - This is the Sahara desert region. Is the lack of rain the effect of it being a desert or is it vice versa?)
#Show the 'Temperature (July) map.
##Where is the weather hotter - northern or southern hemisphere?
##In the northern hemisphere, where is it the hottest? Why?
##Why is it hotter around tropic of cancer in Africa and West Asia, compared to India?
#Show the 'Temperature (December) map.
##Where is the weather hotter - northern or southern hemisphere?
##Why is the southern hemisphere not as hot in December as the northern hemisphere is in July?
##In December, the northern hemisphere has larger areas which are colder, compared to Southern hemisphere during July. Why?
Basically discuss what are the various factor that affect weather/climate - latitude, vegetation/forest area, coastal region v/s hinterland (distance from sea/water body), altitude, land mass vs water body etc)
