After over an hour of impatiently waiting for them to arrive, they finally got off the stuffy bus and breathed in the fresh and salty air of the beach. “Look, there’s a lot of cliffs that have erosion,” said Troye, pointing to one of the cliffs. “Exactly.

Can anyone tell me the three main types of rocks?” asked Zoe. A student immediately raised his hand.
“Igneous, Metamorphic, and Sedimentary rocks,” said PJ. “Good,” said Zoe. “Can anyone describe what an igneous rock is?” She picked up a light colored rock with dark spots all over it.
“I think an igneous rock is when it’s formed through the cooling and solidification of lava or magma. Once the lava cools down, it finally hardens into rock. There’s two basic types: intrusive and extrusive,” said Caspar. “And there’s the metamorphic rock. A metamorphic rock is the result of a transformation of a pre-existing rock. The rock before the transformation is subjected to very high heat and pressure, and it causes the physical change or chemical change of the rock.” Zoe picked up a rock with that had swirly patterns. “They’re generally strong rocks, because their mineral grains grew together tightly using metamorphism.” Zoe stated. “The swirl patterns show the signs of the rock stretching and squeezing.” She handed the rocks to a student to let the whole class feel
