From the mountains to the plains, the earth is covered with a huge variety of fascinating landforms. But how did they get there?
When the ground shakes, there is a hidden cause. The plates in Earth's crust are moving around, and when they collide, it is called an earthquake!
What are Earth's most fantastic, and sometimes most violent, geologic changes? Here is a hint: molten rock and ash are involved!
Some of the world's most famous landmarks were created by weathering and erosion. Ever heard of the Grand Canyon? That is one of them.
Did you know that there is a name for all of the rock on Earth? Sure is. Here are a few names that will come in handy.
You may have heard of minerals. They are important to living things all over the planet.
Can you imagine melting a rock? It takes a lot of heat, but the earth has plenty!
Our planet has layers, and so do some of its rocks! Sedimentary rocks are the product of a lot of pressure, and they even tell a lot about Earth's history.
Take a rock, add a whole bunch of heat and pressure, and presto! You have a new kind of rock: a metamorphic rock.
You might think rocks never change, but that is not true. Like water and nitrogen, rocks have their own cycle, and it is all about change.
You plant flowers in it. Farmers grow our food in it. It is a black and brown feast of minerals for plants. That is right. It is time to talk about soil!
Fossils have stories to tell! These preserved bits of living things tell us a story of what the world was like thousands and millions of years ago.
