7 inch map x (24,000 inch actual/1 inch map) = 168,000 actual inches. 168,000 in x (1foot/12 inches) x 1 mile/5280 feet) = 2.65 miles

35 cm map x (25000 cm actual/1 cm map) = 875,000 cm actual. 875 cm x (1m/100cm) x (1km/1000m) = 8.75 km

If the map scale is 1:25000 and a distance is 7 cm on the map, how many km is it?

7cm map x (1km actual /2.4 cm map) = 2.917 km

equinox, March, September

When both hemispheres of the earth receive the same amount of insolation it is known as the _____ and this occurs in _____ and _____.

The equator

Which latitude has the least variability of insolation levels?

Because the axis is not inclined toward or away from the sun.

Why does an equinox occur

Humidity makes it more difficult for sweat to evaporate which is what cools your body temperature down

Why does humidity make you seem hotter?

The wind takes heat away from the body

Why does wind chill make you feel colder?

insolation at the poles is more spread out because of the tangent angles of insolation, albedo, glaciers and currents affect the amount of energy absorbed or reflected at the poles and during winter they build up more ice during total darkness.

Why doesn't ice melt at the poles during their Summers?

So that countries on the 180° meridian aren't divided by different dates.

Why doesn't the International Date Line follow the 180° meridian?

Because the distance between meridians varies and the distance between latitudinal lines is always the same.

Why is it harder to calculate longitudinal distance than latitudinal distance.
