Power of Eruptions

Question 1

Mount Sunny erupts. Which three things could really happen to the land around the volcano after the eruption?

Accepted Answer

The hot lava cools into hard black rock, the ash settles on the trees making them look gray, and the once‑flat ground now has a new mound of cooled lava.

Answer

The lava melts all the rocks and disappears, leaving a big hole; the ash blows away everything so no soil is left; and the trees grow taller right away.

Answer

The eruption only makes a loud rumble, so nothing on the ground changes, but the sky gets brighter.

Answer

The volcano erupts and the water in the nearby river turns into solid ice, the grass turns into chocolate, and the mountain shrinks.

Question 2

Before a volcano erupted, the land had a green hill and a clear sky. After the eruption, which description shows how the landscape changed?

Accepted Answer

A tall, dark mountain of rock and ash is now on the hill, and hot lava flows down the sides.

Answer

The hill is still green and the sky is still clear.

Answer

A big river appears where the hill used to be, making the area look wetter.

Answer

Many new trees grow instantly on the hill, making it even greener.

Question 3
