Question

1. What are rocks made up of?​

Answer 1

Answer:

Rocks are composed primarily of grains of minerals, which are crystalline solids formed from atoms chemical bonded into an orderly structure. Some rocks also contain mineraloids, which are rigid, mineral-like substances, such as volcanic glass, that lacks crystalline structure.

Answer 2

Rocks are made up of different minerals, which are crystalline solids.

• Rocks are naturally occurring and coherent aggregates of different minerals.
• These aggregates contain the basic unit of which the solid Earth is made up and forms recognizable and mappable volumes.
• Over long periods, layer upon layer of sediments formed, which put fierce pressure on the oldest layers.
• As a result of this great pressure and heat, lower layers of sediments ultimately turn into rocks.
• Rocks are classified into three types based on how they are sourced and formed: 1. Sedimentary 2. Igneous 3. Metamorphic.
