Landform Patterns

Distinct geological formations arise from a variety of natural processes. Fold mountains, exemplified by the Rocky Mountains, are created from thick layers of sedimentary rock at the collision points of tectonic plates, which can later transform into metamorphic rock.

Landform Patterns

Landform Patterns

Fold Mountain

E.g Rocky Mountains
Built from thick layers of sedimentary rock
Where plates collide

Ancient Shields

Many around the Pacific Ring Of Fire
Located on plate boundaries

Plants and Lowlands

Sedimentary Rock
Lowlands: Plains along coastlines
Plains: broad areas of level land
E.g Great plains-St. Lawrence Lowlands

Active Volcanoes

Carves out land from erosion
Later, it forms into metamorphic rock (changes)
Mostly made of igneous rock (solidified magma)
Created by volcanic activity
