What type of rock is formed when sediments accumulate over time and become compacted and cemented together?

✅Explanation:
Sedimentary rocks are formed when sediments (such as sand, mud, and small rocks) accumulate over time and become compacted and cemented together due to pressure. Over time, the particles bind together to form solid rock. This type of rock is typically found in layers and often contains fossils.

📌Other Options Explanations:
-a. Igneous rock: Formed from the cooling and solidification of magma or lava.
-c. Metamorphic rock: Formed from the transformation of existing rocks under high pressure and temperature.

🛑 Additional Information::
The earth's crust is made up of various types of rocks, differing from one another in texture, structure, colour, permeability, mode of occurrence, and degree of resistance to denudation.

• All rocks may be classified into three major groups:
-Igneous Rocks,
-Sedimentary Rocks,
-Metamorphic Rocks.

• 1. Igneous Rocks:
-Igneous rocks are formed by the cooling and solidification of molten rock (magma) from beneath the earth's crust.
-Example: Granite, Gabbro, Basalt, etc.

• 2. Sedimentary Rocks:
-Sedimentary rocks are formed by the process of weathering and cementation or precipitation on the Earth's surface. 
-Example: Sandstones,Kankar, shales, limestones, Mudstones, laterite, etc

• 3. Metamorphic Rocks:
-Formed when rocks are subjected to high heat, high-pressure changes inside the Earth.
-Example: Gneissoid, slate, schist, marble, quartzite, etc.
