Tuesday: Roots hold on

Raven gently pulls up a clump of grass.

Soil hangs from the roots like a beard.

"Whoa," Rocket says. "The roots are holding the dirt!"

"What do you notice about how many roots there are?" Raven asks.

Nova hums. "Hint: think of roots like tiny fingers."

Plants protect soil

Growing roots hold soil in place.

Roots help keep soil from washing away in the rain.

Plants above the ground help shield soil from wind.

On beaches, dune grasses trap and hold sand.
