NATEB GCE GEOGRAPHY ANSWERS

(1ai)
Old scale = 1.50,000
To get the new scale divide the old scale by 2
Ie 150,000/2 = 1/50,000 x ½
Therefore new scale = 1/100,000 = 1:100,000

Gradient between Lokogema and Angwan pasali Gradient = vertical interval/horizontal equivalent
– Legagema is locate on the contour 46om
– Angwan pasali is on the contour 480m
– Horizontal equivalent = 3cm = 30cm
Gradient = 480 – 460/300 = 20/300
= 2/30 = 1/15
Therefore Gradient between Logogema and Angwan pasali is 1 in 15

The north Atlantic Ocean also known as the north Atlantic Drift movement is a powerful warm western boundary current within the Atlantic Ocean that extends the Golf stem northeast ward
The NAC originates from where the GULF stream turns north at the southeast new found land Rise. The NAC flows northward east of the Grand Banks, from 40°N to 51°N before turning sharply east to cross the Atlantic. It transports more warm tropical water to northern latitudes than any other boundary current. More than any other boundary current. More that 40sv in the South and 20sv as it crosses the mud Atlantic Ridge. It reaches speeds of 2knots near the north America Cost directed by in controls to the meanders of the GULF steam the NAC meanders remain stable without breaking one into eddies.
