Q1.
Deposition of glacial or glacial marine strata and
Air static flow of the Arctic Ocean
Q2.
Distribution of ice
Motion of the sea water
Q3.
The rate of chemical weathering would increase with increased temperature and humidity at
the equator. This would lead to a greater rate of chemical weathering.
Q4.
Chemical weathering of rock would lead to absorption of atmospheric carbon dioxide thereby
reducing Green house Gases in the atmosphere and increasing the temperature
Q5.
The decrease in CO2 would cool the planet being unable to trap the solar radiation while an
increase in CO2.would increases the temperature by absorbing heat.
Q6.
Cooling of the lower layers of the atmosphere
It was a negative sign
Q7.
The second radiative forcing was the increase of CO2 and other green house gases due to
volcanic emissions and methane generation. The signs were the cyanobacterial bloom in the
ocean.

Q8.
The feedback was decreasing CO2, a negative feedback in the snowball situation. The end of
snowball was dominated with the increase in CO2 and methane CH4 giving rise to increasing
ocean temperatures.
It was a positive feedback
Q9.
The statement is true
Q10.
In snowball earth the CO2 concentrations were comparatively lower. It would require
excessively higher amount of CO2 that is nearly 350 times of present days CO2 content
Q11.
The North Atlantic Ocean current, the South Atlantic Ocean current and the North Pacific
Ocean Current are the three major ocean currents
Q12.
The Gulf Stream along the east Coast of United states brings warm current from the equator,
and the Kuroshio Current brings warm water from the eastern coast of Japan in the northern
Pacific Ocean.
Q13
The coast of Canada is warmer compared to the coast of England, due to warm Ocean
currents.
Q14.

Running Head: Geography
Due to the warm ocean current that brings water from the equator while the coast of England
is fed by the North Atlantic drift which is relatively colder
Q15.
Canary Islands are cooler than Florida, since the Canary current due to its upwelling is
replaced by cold waters from below. This makes the region colder than Florida.
Q16.
The Sea surface temperature, the upwelling and down welling of the ocean circulations, the
temperature of the currents make a region either cooler or warmer.
