Earth Science Rocks and Minerals

Arjun, Elijah, and Harper are on a treasure hunt and they found a shiny object. They are debating whether it's a rock or a mineral. Can you help them figure out the difference between a rock and a mineral?

• A rock is made up of minerals.

• Rocks are formed through volcanic activity.

• A mineral is made up of rocks.

• A rock is a type of mineral.

Anika, Grace, and Liam are on a treasure hunt and they found a mysterious mineral. They want to determine its hardness. Which scale should they use?

• Mohs scale for hardness measurement of minerals

• A scale for measurement of mineral density

• A scale for measurement of mineral color

• A scale for measurement of mineral transparency

Imagine Ava, Kai, and Grace are on a thrilling adventure to a volcano! They come across two types of igneous rocks. Ava finds one type inside the volcano (intrusive), while Kai and Grace find the other type outside the volcano (extrusive). Can you guess the main difference between these two types of igneous rocks that our brave explorers found?

• The color of the rocks.

• The composition of the rocks.

• The texture of the rocks.

• The formation process/rate of cooling of the rocks.

Imagine Samuel, Abigail, and Aiden are on a thrilling adventure deep inside the Earth's crust. They come across a rock that has changed due to heat and pressure. What is this exciting process called?

• weathering

• metamorphism

• melting

• erosion

Imagine Daniel, Benjamin, and Scarlett are on a thrilling adventure to discover different types of rocks. They stumble upon a mysterious cave with three types of sedimentary rocks. Can you help them identify these rocks?

• Are they igneous, metamorphic, and volcanic?

• Could they be granite, limestone, and sandstone?

• Or are they clastic, chemical, and organic?

• Maybe they are hard, soft, and medium?

Oliver, Rohan, and Maya are on a treasure hunt and they stumble upon a mysterious stone. They wonder what type of stone it could be. Can you help them figure out the two main types of metamorphic rocks they might have found?

• Could it be marble and limestone?

• Or is it granite and basalt?

• Maybe it's igneous rocks and sedimentary rocks?

• Or could it be foliated rocks and non-foliated rocks?
