Coasts are areas of land next to oceans. Coasts can be sandy or rocky and have landforms such as cliffs, sea stacks, caves, and arches. Coasts can be next to open oceans or be sheltered in bays or coves. In this beautifully photographed book, Bobbie Kalman takes children on a tour of different coasts, where they can ride some breathtaking ocean waves or meet underwater animals that live in nearby coral reefs. Children will also be introduced to some amazing coastal cities and learn about famous coastal rock formations.
Why do people need rivers? What causes rivers to flood? These are just a few of the questions answered by this fascinating introduction to rivers by Bobbie Kalman. Topics include the paths of rivers, how rivers carve through rocks, types of rivers, waterfalls, headwaters, tributaries, estuaries, deltas, fiords, river plants and animals, people and rivers, and famous rivers.
In this fascinating book by Bobbie Kalman, children will learn about how mountains and islands form from volcanoes, how wind and rivers create canyons, how rivers and streams create underground caves, how ocean waves shape coasts, and how glaciers make valleys. They will enjoy looking for rock formations in the shapes of animals, trees, and even ghosts!
This fascinating book explains to young children why the land on Earth has different shapes in different places. Amazing photographs and illustrations show examples of continents, mountains, valleys, plains, and caves, as well as the forests, animals, and water that may be found on each landform. Simple text also describes what volcanoes are and how lava flows can create mountains. The role that weather, such as rain and strong wind, plays in shaping sand dunes, mesas, buttes, and canyons is also described.
