Study Notes
Landforms and Their Influence
- Landforms are shapes on Earth's surface, like mountains, valleys, plains, and islands.
- Mountains rise above 2,000 feet (610 meters).
- Valleys are low areas between hills or mountains.
- Plains are flat stretches of land.
- Islands are areas of land completely surrounded by water.
- Peninsulas are land surrounded by water on three sides.
- Landforms influence human life and are studied by geographers.
Earth's Plates
- Earth's crust is made up of tectonic plates.
- These plates move slowly (a few inches per year).
- Collisions, separations, and shifting of these plates cause forces that shape landforms.
- Continents are part of Earth's crust called plates.
- Some plates are large (like the Pacific plate), others are smaller (like the Nazca plate).
- Plates under the ocean are called ocean plates.
- Plates under continents are known as continental plates.
Forces Shaping Earth's Surface
- Earth's structure includes a solid inner core, a liquid mantle, and a solid crust.
- The crust is where continents lie.
- Plate tectonics explains how forces below the surface shape landforms.
- Energy deep within Earth pushes the plates causing them to shift and move.
- Plate movement causes various landscapes.
- Scientists study how landforms are created and their effect on human activities.
