What are grains (rock)?
particles of minerals and other rocks that make a rock
How are rocks and grains different?
Rocks are composed of one or more minerals, while grains are small, individual particles of a mineral. Rocks can be made up of different types of minerals and have a variety of sizes and shapes, while grains are typically uniform in composition and size. Rocks are larger and can be made up of multiple grains, whereas grains are individual, tiny fragments.
Why is the texture of obsidian is best contain few or no minerals grains?

The particles of minerals or other rocks that make up a rock is called?
The particles of minerals or other rocks that make up a rock are called grains or crystals. These grains can vary in size and shape based on how the rock was formed and the types of minerals present within it.
What are the three types of lithification?
The three types of lithification are compaction, cementation, and recrystallization. Compaction involves the squeezing together of sediment grains, cementation involves the precipitation of minerals in the spaces between grains to bind them together, and recrystallization involves the transformation of existing minerals into new minerals.
What did the egyptians trade with the Phoenicians?

What are the characteristics of grains?
Grains are small, hard, dry seeds harvested for human consumption. They are rich in complex carbohydrates, fiber, vitamins, and minerals. Grains can be categorized as whole grains or refined grains, with whole grains being more nutritious due to their higher fiber and nutrient content.
When grains are processed what is removed?
When grains are processed, the outer layer (bran) and germ are often removed, leaving mainly the starchy endosperm. This results in refined grains that have lost some of the fiber, vitamins, and minerals present in whole grains.
What kind of sediments consist primarily of minerals grains that were eroded from rocks on land?
