ROCK CYCLE

Match the following rock with its description -

• IGNEOUS ROCK

• Created from the deposition of sediments in layers over long periods of time.

• SEDIMENTARY ROCK

• Usually underground, existing rock is transformed by very high heat & pressure.

• METAMORPHIC ROCK

• Created from the cooling and solidification of magma or lava.

Match the following rock with its types -

• IGNEOUS ROCK

• pumice, obsidian, granite

• SEDIMENTARY ROCK

• shale, limestone, conglomerate

• METAMORPHIC ROCK

• gneiss, marble, schist

Magma (the molten rock present deep inside the earth) or lava on earth's surface following a volcanic eruption, solidifies due to rapid cooling and crystallizes to form a type of rock called ​ (a)   .

• igneous rocks
• metamorphic rocks
• sedimentary rocks

Due to weathering and erosion, the igneous rocks are broken down to form sediments which get compacted and compressed together for extended periods to form ​ (a)   .

• igneous rocks
• metamorphic rocks
• sedimentary rocks

Over a very long period of time, sedimentary and igneous rocks end up being buried deep underground the soil. Deep below the surface, these rocks are exposed to high heat and pressure, which change them into a different type of rock called ​ (a)   .

• igneous rocks
• sedimentary rocks
• metamorphic rock

Match the following TERM with its definition -

• WEATHERING

• Carrying away of broken rocks by rain, streams, rivers, and oceans to a distant place from their origin.

• Compaction

• During the carriage of rocks by rivers, the rock particles (mixed with soil) sink and become a layer of sediment. Often the sediments build up and form small accumulations, which over time and pressure turn into sedimentary rock.

• Cementation

• The process in which sediment is squeezed due to the weight and pressure of overlying layers.

• EROSION

• Igneous, sedimentary, and metamorphic rocks present on the surface of the earth are constantly being broken down by wind and water over a long time.

• DEPOSITION

• The process in which sediments are glued together by minerals that are deposited by water.
