CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers.

Detailed explanation-2: -Based on formation, rocks are classified into three categories-Igneous, Sedimentary and Metamorphic. Igneous rocks are formed by the cooling and solidification of the molten material. Sedimentary rocks are formed by the compaction and hardening of bits of rocks and soil deposited in layers over millions of years.

Detailed explanation-3: -Igneous rocks are formed from melted rock deep inside the Earth. Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons. Metamorphic rocks formed from other rocks that are changed by heat and pressure underground.

Detailed explanation-4: -There are two different ways that rocks are often classified; the first is based on the processes by which they form, in which rocks are classified as either sedimentary, igneous, and metamorphic. Rocks are also commonly classified by grain or crystal size.
