Quartz
Mica
Granite
Clay
Answer is Right!
Answer is Wrong!
The correct answer is D. Clay.
Clay is a fine-grained, naturally occurring mineral that is plastic when wet and hardens when fired. It is used to make pottery, bricks, and other objects.
Quartz is a hard, brittle mineral that is found in rocks and sand. It is not plastic.
Mica is a group of minerals that are found in rocks and soil. It is not plastic.
Granite is a hard, igneous rock that is composed of quartz, feldspar, and mica. It is not plastic.
Clay is a highly plastic substance because it is made up of small, plate-like particles that can slide past each other when wet. This allows clay to be easily molded into different shapes. When clay is fired, the water evaporates and the particles bond together, forming a hard, durable material.
