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!

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.

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.

This magnificent book uses beautiful photography to help young children understand that oceans are a type of habitat or place in nature where plants and animals live. Simple text explains why some oceans are warm and some are cold, which kinds of plants and animals live in oceans, and how the bodies of ocean animals are built to help them glide through water. Other topics such as photosynthesis, tide pools, and coral reefs are briefly and simply explained. Children will be delighted by the images of seals, penguins, polar bears, dolphins, and more.

This extraordinary book shows in a simple way how the Sun's light and warmth affect Earth. Children will be amazed to learn that the Sun is actually a star, and that its position and distance from the Earth cause day and night as well as changing weather and the seasons.
