may have volcanic activity

Explanation:

The Pacific Islands that lie along tectonic plates may have volcanic activity

A. may have volcanic activity

Explanation:

Volcanic activity results in the emission of dangerous gases that are explosive and lasts for long hours when they occur. Sudden energy release lead to the occurrence of the volcanoes that is caused by the movement of magma on the surface.

The volcanoes, therefore, erupt when magma is in the surface; magma itself occurs when the earth melts. Melting occurs when the tectonic plates pull apart or when one plate is pulled down. When the magma is thick, it is difficult for gas bubbles to escape, and because of this pressure builds up, leading to the rising of magma.

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.
