A Landforms Adventure
Road Trip! We're going on a road trip this summer! My parents and I are driving from Boston to Seattle. My class has been learning about landforms in school. We're going to see some amazing landforms on the trip!
In Class My teacher, Mr. Lopez, said that Earth's crust is made up of huge pieces of rock called plates. Some of the plates are larger than continents! The plates sit above melted rock and slowly slide around because of heat deep inside Earth. The moving plates can create landforms.
Mr. Lopez also said that Earth's surface is always changing. He said that some changes are slow, while others are fast. Old landforms can change over time, and new ones can be created. Some landforms result from changes underground. Hot, melted rock under Earth's surface can build up and form a volcano. A volcano is a type of mountain.
Other changes happen on the surface. Weathering breaks down rock and shapes it. Erosion carries away the pieces that have broken off, Wind, water, and ice are the main tools of weathering and erosion. Mr. Lopez handed out a list of different landforms. I'm going to take the list on my trip and try to see them all!
Getting Ready to Leave Mom and I start at Castle Island, in Boston Harbor. It's not really an island since it doesn't have water all around it. It's connected to the mainland on one side, so it's a peninsula. You can see a bunch of islands from there, though.
