Write a hypothesis that describe how you think the rock model with stones will break down.

Weathering

Explanation:

Weathering is the process by which rocks breakdown or dissolve into smaller stones on the surface of the Earth. The agents of weathering are Water, ice, acids, salts, plants, animals.

Once a rock has been broken down, a process called erosion transports the bits of rock away. No rock on Earth is hard enough to resist the forces of weathering and erosion.

Weathering is often divided into two :

1) Mechanical weathering, also called physical weathering and disaggregation, causes rocks to crumble.

2) Chemical weathering changes the molecular structure of rocks and soil.

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.
