Activity extension: Landslide stoppers!

Engineers have come up with many ways to protect homes and stop landslides. Here are a few of our favorites.

You can change the slope of the hillside with walls and terraces or make barriers designed to catch falling rocks.

To protect a road or house, you can build a rock shed like this one or design a radically different house like this one that’s shaped like a soccer ball.
