Rocks formed from sedimentary or igneous rocks under heat and pressure.

The Greek word for 'transformation', related to how metamorphic rocks change.

Appearance of metamorphic rocks with aligned mineral layers.

A metamorphic rock formed from granite under high temperature and pressure.

A foliated metamorphic rock formed from shale.

The continuous process of rock transformation between igneous, sedimentary, and metamorphic rocks.

An igneous rock found predominantly in the central part of Singapore.

Location in Singapore with some presence of metamorphic rocks.

A tool made from a sharp stone tied to wood, historically used by people near the Hoko River.

Solid materials that make up the Earth's crust, composed of minerals like quartz and sand.

Geologists classify rocks into igneous, sedimentary, and metamorphic based on their formation.

Rocks formed from cooled magma, either beneath or above the Earth's surface.

Igneous rocks that form when magma cools slowly inside the Earth.

Rocks formed from particles or sediment, often containing fossils and layered structures.

Examples include basalt, granite (igneous), limestone, sandstone (sedimentary), and marble (metamorphic).

Rocks formed from lava that cools quickly on Earth's surface, resulting in small grains.

A fine-grained igneous rock formed from rapidly cooled lava, used for tiles and fiberglass.

Tiny pieces of broken rocks, sand, clay, and silt, carried by wind and water.

Rocks formed from very small sediments, requiring a microscope to see details, like shale.

Rocks formed from larger sediments, like sandstone and conglomerate, visible to the eye.

A sedimentary rock formed from hardened remains of marine life and may contain fossils.
