Exploring Earth’s Surface
EQ: How do I describe the topography and spheres that make
up the Earth’s surface?
G1-1
Topography – shape of the land
Determined by an area’s Elevation - height above sea level of a point on
Earth’s surface Relief – difference in elevation between the highest
and lowest parts of an areaLandforms – feature of topography formed by the
processes that shape the Earth’s surface. All landforms have elevation and relief
Landform region- large area of land where the topography is similar
EQ: How do I describe the topography and spheres that make up the Earth’s surface?
G1-1
Types of Landforms
There are three main types of landforms–Plains–Mountains–Plateaus
EQ: How do I describe the topography and spheres that make up the Earth’s
surface?
G1-1
Plains
A landform made of flat or gently rolling land with low relief
Two types of plainsCoastal plain Interior plain
EQ: How do I describe the topography and spheres that make
up the Earth’s surface?
G1-1
Coastal plain – plain that lies along the seacoast, low elevation and low relief i.e. area of land that wraps along the eastern and southeastern shores of the USA
EQ: How do I describe the topography and spheres that make up the Earth’s surface?
G1-1
Interior plain – a plain that lies away from the coast. Elevation can vary, but relief is lowi.e. Great Plains
EQ: How do I describe the topography and spheres that make up the Earth’s surface?
G1-1
MountainsA landform with high elevation and high relief
Mountain Range – a group of mountains that are closely related in shape, structure and age
EQ: How do I describe the topography and spheres that make
up the Earth’s surface?
G1-1
Plateaus
Landform with high elevation and more or less level surface (low or no relief)
The Piedmont region of North Carolina (where we live) is a plateau

topography and spheres that make up the
Earth’s surface?

Earth’s Four Spheres
• Lithosphere• Atmosphere• Hydrosphere• Biosphere
EQ: How do I describe the topography and spheres that make up the Earth’s surface?
G1-1
Lithosphere
• Earth’s solid rocky outer layer. Makes up the earth’s crust and uppermost mantle
• Made of continents, islands, and ocean floor
• Surface varies from smooth plains to jagged mountain peaks
EQ: How do I describe the topography and spheres that make up the Earth’s
surface?
G1-1
Atmosphere
Outermost sphereA mixture of gases that surround a planetEarth’s atmosphere mostly made of nitrogen and oxygenAlso contains water vapor , carbon dioxide and other gases
EQ: How do I describe the topography and spheres that make up the Earth’s surface?
G1-1
Hydrosphere
• All the water on Earth including oceans, lakes, rivers, and ice
• Most of our water is ocean
EQ: How do I describe the topography and
spheres that make up the Earth’s surface?
G1-1
Biosphere• The sphere or area around the planet Earth where life exists. Most life forms live on, or near the surface of Earth.
• Some live deep within the hydrosphere
• Others thrive in the depths of the lithosphere (solid portion of Earth).
