How Do Mountains Form?
SPI’SScience 7.7.1, 7.7.2
Reading 5.1.2, 5.1.7, 5.1.12, 5.1.16, 5.1.17, 5.1.28, 5.1.30, 5.1.31
Main Idea
You will name and describe the four types, or classes of mountains.
See if you can figure out what type mountains the Smokies are!
Let’s write our vocab. definitions in our Science
Journals
Dome mountains– mountains that form when magma pushes up on Earth’s crust but does not break through.
Vocab. Cont…
Fault-block mountains- mountains that form along fault lines where blocks of rock fall, are thrust up, or slide.
The Rocky Mountains are fault-block mountains, and they are located in
the Southwestern region of our country. P. 229 of your text has a picture of a fault-block mountain.
Vocab. Cont…
Fold mountains- mountains that form where two plates collide and force layers of rock into folds.
(On P. 228 of your text is a picture of the Andes Mountains which are
Fold Mountains.)
Who Remembers what we’re learning in this lesson?
We’re learning to describe the four types, or classes of mountains.
Mountain Formation
We’ll read PP. 228 and 229. I need a volunteer to begin reading on P. 228. Be sure to ask yourself questions about the text as you read. (This technique helps you understand what you are reading…)
In your Science Journals…
Summarize: What are two ways in which mountains are formed?
Contrast: How do older mountains differ from younger mountains?
Compare: What do fold mountains and fault-block mountains have in common?
Read to find out…
We’ll read PP 230 and 231 to find the following information:
Where does volcanic activity occur?oHow do dome mountains form?Which mountains have been shaped by erosion?How do erosion mountains differ from all other types of mountains?
The Appalachian Mountains
Ahhh, these are OUR mountains!!! Follow along in your text while I read P. 232. There will be a 20 question
quiz over chapter 6, so PAY ATTENTION while I’m reading!!
