1.

Explain how sedimentary rock is formed.

2.

Match each scenario to the type of rock it is describing.

This rock was formed in La Fortuna, Costa Rica after the explosion of the Arenal volcano in 1968. Today, the entire area is covered in structures formed by this rock and it is very ashy.
In 2004, team of paleontologists discovered the 375 million year old fossil of a Tiktaalik, an ancient fish.
Marble comes from limestone and other minerals that have been heavily altered by heat and pressure underground. We now use it to build monuments and countertops!
Obsidian is formed when lava rapidly cools down. It was used by many Native American cultures to craft weapons because of how sharp it is.
