What can be used to form fossils?
What is bones or leaves?

How does soil form?
What is soil forms when weathering causes rocks to break apart, such as with water and plant roots?

What is a mineral's way it reflects light?
What is luster?

What are some types of sedimentary rocks?
What is a rock that forms from sediments made of materials that were once living things (such as limestone)? Another type is made up of bits of minerals that are the size of grain (such as sandstone). Lastly, the third type is mudstone, it forms in lakes or oceans where very tiny particles settle.

How can a sedimentary rock form into a metamorphic rock?
What is by applying heat and pressure?

Magma that slowly cools below Earth's surface forms igneous rocks that have... what?
What is large crystals?

What does soil contain?
What is soil contains small bits of rock, decaying plants and animals, and tiny life forms?

What are the physical properties that scientists use to identify a mineral? (Name 5)
What is by its color, luster, harness, streak, and cleavage?

How do igneous rocks form?
What is igneous rocks form from molten rock when it cools?
500
What is the hardest mineral out there? What about the softest?
What is a diamond is the hardest mineral and talc is one of the softest minerals?

How does an organism become a fossil?
What is after an animal dies,the soft tissues of its body devay; bones and shells remain? Sediments bury the remains in successive laters. Over time, the remains may be replaced with minerals that eventually harden into rock. Weathering and erosion may eventually cause the fossil to appear on Earth's surface.

What can weathering cause?
What is weathering can cause rocks to wear away?

How do metamorphic rocks form?
What is metamorphic rocks form through heat and pressure over time?
