A tree begins to grow on a mountain in a dry area with a warm climate. After many years, a pile of small rock pieces forms at the bottom of the mountain. The pictures show the tree and mountain over time.

What MOST LIKELY caused the rock to break into pieces?

• Animals dug deep into the rock.

• Flowing water broke apart the rock.

• Growing tree roots broke apart the rock.

• Water froze and cracked the inside of the rock

A flash flood and earthquakes are the same because

• both are fun to ride

• both create mountains

• they are caused by thunderstorms

• both cause rapid erosion
