The correct option is D A:3, B:4, C:1, D:2

Solution: Option D

Explanation:

EARTHA:
The world's largest rotating globe, nicknamed "Eartha", is located at the headquarters of DeLorme, U.S.A. This globe is 41 feet in diameter and weighs 2,500 kg, it is so big that you need to take the stairs to the second or third floor to see the northern hemisphere.

Moisture:
The air that has a greater amount of vapor is called humid air. The humidity in the atmosphere is called moisture. The proportion of moisture in the atmosphere depends on temperature. Air with higher temperatures holds a greater amount of moisture.

Weather
The weather can be termed the short-lived atmospheric conditions prevailing at a place and at a given time.

Planktons
Plankton is a collection of tiny organisms that live at and beneath the surface of lakes, rivers, ponds, and oceans across the planet. They’re named after the Greek word planktons, meaning to drift or float. Plankton doesn’t swim on their own—they’re carried by tides, currents, and other forces, which determine where they go. Plankton is an important food source for many large and small ocean creatures. They also play a vital role in absorbing carbon dioxide and producing oxygen in the ocean.
