Correct Answer: Option 3 – Southeast The distance between the stream and the southern reference point is reducing as it moves towards the right which is the east. Hence, as indicated by the direction indicator next to the map the general direction of the stream is southwest.

Correct Answer: Option 3 – 30 ft/mi

The contour interval given is 20 feet. And there are 3 contours between points X and Y. Also using the scale of miles, points X and Y lie approximately 2 miles away. Hence, the gradient between X and Y is

Correct Answer: Option 1 – Earth's rotation and unequal heating of Earth's surface

Planetary wind belts are related to the general circulation of the atmosphere. In this circulation there are three cells of vertical circulation. Try to picture a cross-section of the earth. At the equator the air rises with heating and in the upper atmosphere begins to flow toward the north. At about 30 degrees north latitude it sinks and flows back toward the equator forming the easterlies in the band from 30 N to the equator. This cell is the Hadley circulation. Between 30 N and about 60 N there is a similar circulation but in a reverse mode. It flows at the surface from 30 N to 60 N where it rises along the Polar front and returns aloft by flowing southward where it sinks at 30N. This cell is called the Ferrel cell. Finally, north of 60 N there is the Polar cell which in the upper atmosphere flows toward the Pole where it sinks and flows southward near the surface forming the polar easterlies. Where the Ferrell and Hadley cells sink at 30 N we have the Horse latitudes an area of generally high pressure. This same pattern is repeated in the southern hemisphere

Correct Answer: Option 2 – Bedrock type, structure and elevation

The paragraph that describes the classification of landscape regions is based on the length of mountains, nature of bedrock formed, rolling hills, and valleys. Hence, option 2 is the correct answer.

Hence, the other options 1, 3 and 4 are incorrect.

Correct Answer: Option 1 – Vermont Lowlands

This is evident from the figure

Hence, options 2, 3 and 4 are incorrect.
