C Correct answer
Explanation

Earth takes about 365 1/4 days to revolve around the sun. As we take 365 days for a year, the difference of 1/4 of a day requires adjustment. This is why we add one day to February every four years.

A Correct answer
Explanation

1;The earth rotates around its vertical axis. The axis is an imaginary line passing through the centre of the earth. Its two ends on the surface are called North and South poles The Earth completes one rotation in 24 hours. 

2:The Earth's axis is vertical, meaning it runs up and down. (A rolling log, on the other hand, has a horizontal axis, meaning it runs sideways.) The Earth's axis runs from the North Pole to the South Pole. It takes the Earth 24 hours, or one day, to make one complete rotation around this invisible line

Wind erosion has the greatest impact on areas with __________.

  1. wet soil

  2. dry soil

  3. both a and b

  4. none of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Wind erosion has the greatest impact on areas with dry soil because it is easier for wind to pick up and transport dry, light soil. Characteristically, deserts have dry soil, or sand, that is easy to transport. Also, deserts often have fewer physical barriers, such as hills, trees, or other structures, that can slow the wind movement.

The huge mass of ice and snow moving slowly is called __________.

  1. glacier

  2. moraine

  3. magma

  4. lava
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The moving ice mass downslope under the impact of gravity is called a glacier. About 10 percent of the earth's surface is now covered by the glacier. Glacier is formed due to the accumulation of ice above snow-line under extreme cold climate.
