Glacial deposition is the settling of sediments left behind by a moving glacier. As glaciers move over the land, they pick up sediments and rocks. The mixture of unsorted sediment deposits carried by the glacier is called glacial till. Piles of till deposited along the edges of past glaciers are called moraines.

  1. Glacioscerpe

  2. Glaciations

  3. Fluvialglacio

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Fluvioglacial landforms are landforms molded by glacial meltwater. This discharge of glacial streams, both over the surface and beneath the ice sheet, is higher in the warmer summer months. As subglacial water often flows under pressure, it has a high velocity and is very turbulent.

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Earth is a non-luminous body but the sun is luminous. As the earth is rotating around its axis, half of its portion is facing the sun and the other half is entirely dark due to the absence of sun. In other words, half of the globe have day and on the other half, it is a night. As the earth is rotating around the sun its every part is exposed to Sun within every 24 hours this rotation causes days and nights.

  1. Rotate around the sun

  2. Rotate around itself

  3. Revolve around the sun

  4. Revolve around itself

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.

The axis of rotation of the earth is __________.

  1. Vertical

  2. Horizontal

  3. Tilted

  4. Both A and B
Reveal answer Fill a bubble to check yourself
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
