EARTHSCAPES with texts and colored photographs transports you to tall frozen mountains, wanders seashores, roams streams and rivers, and ventures onto parched deserts. Along the way you learn how internal Earth force, water, wind and ice carve and deposit many landforms of great beauty. Most landforms evolve by small increments over thousands of years, but few occur in catastrophic bursts, landslides and volcanic explosions, causing hazards for humans. Thin extensive layers of human engineering obscure large natural areas.
