Guided practice

1
Read this passage: "Mountains seem like the most permanent things on Earth. Cities rise and fall, rivers shift their banks, but a mountain — surely a mountain stands still? In fact, mountains are moving all the time. The Earth's outer shell is broken into enormous plates that slide, very slowly, across the planet's hot interior. When two plates push against each other, the rock between them crumples upward over millions of years. That is how the Himalayas rose, and they are still rising — about a centimeter every year, roughly the speed at which fingernails grow. Other mountains are wearing down. Wind, ice, and rivers carry tiny grains away day after day. A mountain that took fifty million years to push up may take another fifty million years to grind down. From a human lifetime it looks unchanged. From the Earth's, it is in constant motion." Q: What is the main idea?
Parent tip: Read aloud once, then ask your child to read it back. Underline answers together.
2
Using the same passage, answer: How fast are the Himalayas rising?
Parent tip: Point back to the line in the text that proves the answer.
