The south american plate is being pulled westward at a rate of approximately 3.3 centimeters per year. how many kilometers west has it moved in the last 100 million years?

The answer is 3,300km

100,000,000 x 3.3=330,000,000cm

100,000cm-1km

330,000,000 divide by 100,000 = 3,300km

Explanation:

the wrong statement is - c. a desert had more biodiversity than a marsh.

the deserts are one of the places of the planet where there's the least biodiversity. the reasons for that are the climate and the lack of food sources, which hampers both the number of the species that can survive in it, and the number of the individuals in the species itself.

the marshes, on the other hand, are places where there's perfect conditions for lots of organisms to thrive. the temperature is moderate and nice, the amount of water and the food sources are on a high level, so there's an abundance of both plant and animal life in them.
