Topography includes Elevation – height above sea level of a point on the earth’s surface Elevation – height above sea level of a point on the earth’s surface Relief – difference in elevation between the highest and lowest parts of an area. Relief – difference in elevation between the highest and lowest parts of an area. Landforms – a feature of topography (hill, valley, river, etc. Landforms – a feature of topography (hill, valley, river, etc. Topography includes Elevation – height above sea level of a point on the earth’s surface Elevation – height above sea level of a point on the earth’s surface Relief – difference in elevation between the highest and lowest parts of an area.

Height and elevation are not the same! Height is the distance of something from the base to the top. Elevation is the distance above sea level. Height and elevation are not the same! Height is the distance of something from the base to the top. Elevation is the distance above sea level.

LANDFORMS

Types of Landforms Plains – nearly flat or gently rolling land with low relief Plains – nearly flat or gently rolling land with low relief Types of Landforms Plains – nearly flat or gently rolling land with low relief Plains – nearly flat or gently rolling land with low relief

Types of Landforms Mountains – high elevation and high relief. Mountains – high elevation and high relief. Types of Landforms Mountains – high elevation and high relief. Mountains – high elevation and high relief. Mountain range – group of mountains that are closely related in shape, structure, and age.

Types of Landforms Plateaus – high elevation and a more or less level surface. Plateaus – high elevation and a more or less level surface. Types of Landforms Plateaus – high elevation and a more or less level surface. Plateaus – high elevation and a more or less level surface.

Landform Regions A large area of land where the topography is made up mainly of one type of landform.
