Question

The sand in a beach is red in colour.
Which of the following is a factor responsible for the colour?

• A. Weather
• B. The rock from which the sand is made
• C. Sunlight
• D. None of the above

Answer 1

The correct option is B The rock from which the sand is made

The colour of sand depends on the colour of the rock it weathered from.

If the sand is red in colour, it is because the rock from which it was formed would have been rich in iron, which gives the rock it’s red colour.
