At the beginning of the Cambrian Period, about 542 million years ago, there were sea creatures like hydras, jellyfish, sponges and seaweed living in the oceans, but only one-celled algae on land yet. Small arthropods like beetles were beginning to appear, and by 540 million years ago the first land plants evolved from the land algae. These plants were like modern moss.

Convergent plate boundaries can form which of the following?Rift Valleys
Deep Ocean Trenches
Mountains
Volcanic Island Arcs
New Ocean Floor

Answers

Answer:

Deep Ocean Trenches, Volcanic Island Arcs and mountains

Explanation:

At a convergent plate boundary two plates collides with one another. Based on the type of plate, different features can form at such a margin.

In a continental - continental crust collision, both plates have the same density so, they build up on collision to form a mountain.
In an oceanic - continental crust convergence; the oceanic plate is denser and it subducts. This leads to the formation of trenches. Also, here, the subducted plate will melt and a crack within the crust can allow for the melt to reach the surface and solidify to form volcanic Island arcs.
Oceanic - oceanic crust convergence is also known.
