Section 1
Landforms Shape Earth's Diverse Surface
Earth's surface features include mountains, valleys, plateaus, beaches, and deserts. Each landform has specific characteristics and forms differently through natural processes over time.
In this Grade 5 lesson from Science: A Closer Look, Chapter 4, students learn to identify and classify Earth's landforms and water features, including mountains, plateaus, canyons, rivers, deltas, and estuaries. The lesson also introduces ocean floor features such as the continental shelf, continental slope, abyssal plain, and submarine canyons. Students practice observing, describing, and grouping physical features of Earth's surface using real-world examples from across the United States.
Section 1
Landforms Shape Earth's Diverse Surface
Earth's surface features include mountains, valleys, plateaus, beaches, and deserts. Each landform has specific characteristics and forms differently through natural processes over time.
Section 2
Ocean Floors Hide Mountain Ranges and Valleys
The ocean floor contains diverse features including continental shelves, abyssal plains, trenches, seamounts, and mid-ocean ridges. Scientists use sound waves and underwater vehicles to map these hidden landscapes.
Section 3
Maps Transform 3D Landscapes into 2D Representations
Relief maps use shading to create a three-dimensional appearance, while topographical maps use contour lines to show elevation. Closely spaced contour lines indicate steep terrain; widely spaced lines show gradual slopes.
Section 4
Earth Divides Itself Into Distinct Layers
Earth consists of several layers: the atmosphere (gases), hydrosphere (water), and solid layers including the crust, mantle, outer core, and inner core. Living things inhabit the biosphere, from deep oceans to lower atmosphere.
