2nd grade nonfiction canyons and rivers 129 words

A River Carves a Canyon

A canyon is a deep valley with steep sides. Some canyons are so deep that the river at the bottom looks like a thin ribbon. How could a river make a hole that big?

The river did it with time. Water by itself is soft. But a river carries sand and small stones. As the river flows, these bits scrape the rock below. Each scrape takes away a tiny bit of stone.

One scrape is too small to see. But the river keeps flowing day after day, year after year. Slowly, it cuts down into the ground. The canyon gets deeper and deeper.

The Grand Canyon in Arizona is a famous example. The Colorado River cut it over a very long time. The river is still flowing there today.

A canyon is a deep valley. Its sides are steep. Some are so deep that the river looks like a thin ribbon. How can a river make a hole so big?

It takes time. Water is soft. But a river carries sand and small stones. They scrape the rock. Each scrape takes off a tiny bit.

One scrape is too small to see. But the river flows day after day for years. It cuts down into the ground. The canyon gets deeper.

The Grand Canyon is in Arizona. The Colorado River cut it. It took a very long time. The river still flows there.

A canyon is a deep valley with extremely steep sides. In some canyons, the river at the very bottom looks like a thin ribbon far below. How could a river possibly carve such an enormous hole?

The river accomplished it with time. Water by itself is soft, but a flowing river carries sand and small stones along with it. As the river rushes forward, these bits scrape against the rock beneath, and every scrape removes a tiny piece of stone.

A single scrape is far too small to notice. However, the river keeps flowing day after day and year after year, slowly cutting down into the ground, until the canyon grows deeper and deeper.

The Grand Canyon in Arizona is a famous example of this. It was carved by the Colorado River over a very long span of time, and that river is still flowing there today.

Ideas for class

  • Before reading, put canyon, steep, scrape and carries on the board with their meanings from the Words to know section and have students predict what the text will be about.
  • Read it aloud once while students follow along, then have them reread it alone or with a partner. At a calm 100 words a minute it takes about 1 minute to read aloud.
  • Use the Read it big button (or B) to put the text on the projector, and Show answer on one question at a time so the class commits to an answer first.
  • Question 5 asks the reader to infer. Ask students to point to the words in the passage that led them to their answer.
  • Ask students to write one question the passage did not answer, then look for the answer in a book or on a classroom screen.
  • Print the student copy for independent work and keep the answer-key copy for yourself.
