Question

plate tectonics: convergent boundaries dense continental crusts collide. this results in the formation of mountain ranges, and one outstanding example is the himalayan mountains. these peaks are still rising today and hold a remarkable secret - fossils of ancient sea creatures! this discovery suggests that the area was once submerged under a much deeper ocean or sat at a lower elevation. what geological features are typically formed at continent - continent convergent boundaries? mountain ranges oceanic trenches rift valleys

Explanation:

The text states that when dense continental crusts collide at continent - continent convergent boundaries, mountain ranges are formed, with the Himalayan Mountains as an example. Oceanic trenches form at ocean - continent or ocean - ocean convergent boundaries, and rift valleys form at divergent boundaries.

Answer:

A. Mountain ranges
