Earth’s crust is covered with layers of deep soils and fine-grained clays. These layers are in constant motion and they move at about the rate fingernails on hands grow. Over time, this movement causes intense heat as the rocks push, grind, and collide with enormous force. These gradual conditions make three different types of rock known as SEDIMENTARY, METAMORPHIC,and IGNEOUS.
In this video, Bill Nye helps us to explore Earth’s soil and rock formation in more detail. Bill starts by first showing us how interesting this topic can be.
