Question

identify and describe physical features that are the result of plate movement)

Explanation:

To answer this, we analyze physical features formed by plate tectonics:

1. Mountains (e.g., Himalayas): Formed by convergent plate boundaries where two continental plates collide (e.g., Indian and Eurasian plates). The collision causes the crust to buckle and fold, creating large mountain ranges.

1. Volcanoes: Often form at convergent (oceanic - continental or oceanic - oceanic) or divergent boundaries. At subduction zones (convergent), one plate sinks, melting the mantle above to form magma that rises to create volcanoes (e.g., Pacific Ring of Fire). At divergent boundaries (e.g., mid - ocean ridges), magma rises to form new crust and can create underwater volcanoes (some become islands like Iceland).

1. Ocean Trenches: Form at convergent boundaries where an oceanic plate subducts under another plate (e.g., Mariana Trench, where the Pacific plate subducts under the Philippine plate). The subducting plate creates a deep depression in the ocean floor.

1. Rift Valleys: Form at divergent boundaries on land, where continental plates pull apart (e.g., East African Rift Valley). The crust stretches and thins, eventually creating a valley as the plates move apart.

1. Mid - Ocean Ridges: Form at divergent boundaries in the ocean, where tectonic plates move apart. Magma rises to fill the gap, creating new oceanic crust and a long, underwater mountain range (e.g., Mid - Atlantic Ridge).

Answer:

Some physical features resulting from plate movement include:

• Mountains (e.g., Himalayas): Formed by continental - continental plate collision, causing crustal folding and uplifting.
• Volcanoes (e.g., those in the Pacific Ring of Fire): Formed at subduction zones (convergent) or divergent boundaries, from rising magma.
• Ocean Trenches (e.g., Mariana Trench): Formed at subduction zones (convergent) where an oceanic plate sinks.
• Rift Valleys (e.g., East African Rift Valley): Formed at continental divergent boundaries as plates pull apart.
• Mid - Ocean Ridges (e.g., Mid - Atlantic Ridge): Formed at oceanic divergent boundaries, creating new oceanic crust.
