This book discusses the make up of soil, its formation and how taking care of soil will reap benefits for all living things. Reading Essentials in Science.
All plants need sun, water, air, and food to grow. Plants are anchored to the ground by their roots, which take in nutrients from the soil. Stems and stalks hold up plants and give them shape, and also hold the plumbing system of the plant. Leaves are the place where food is made for the plant. Many plants make crops for us to eat.
Landforms are features on the earth's surface that are made naturally. Mountains, plains, and plateaus are all examples of landforms. The study of landforms is called geomorphology. Scientists can learn about the past and even predict future changes by studying landforms. Today we can take pictures of landforms from airplanes and satellites.
We live on Earth's crust, but there are other layers beneath the crust. They are the mantle and the outer and inner core. In 1915, scientist Alfred Wegener said that about 200 million years ago, Earth once had a single landmass. Hot, molten magma under the surface of the crust pushed the plates apart at a crack in Earth's crust and, eventually, the landmass was split apart and continents were formed. Wegener's work led to the study of plate tectonics.
This book discusses the science behind tornadoes and their effects. The chapters describe deadly tornadoes, examine the weather conditions that cause tornadoes, and explain how people prepare for these disasters. Diagrams, charts, and photos provide opportunities to evaluate and understand the scientific concepts involved.
