Sedimentary Rock Noun

---

[sed-uh-men-tree rok]

Back

Sedimentary Rock

---

A type of rock formed from the accumulation and solidification of mineral or organic particles at the Earth's surface.

---

Example: Layers of sediment are deposited over time, forming sedimentary rock.

Limestone Noun

---

[lahym-stohn]

Back

Limestone

---

A sedimentary rock composed primarily of calcium carbonate, often formed from the remains of marine organisms like shells and coral.

---

Example: Limestone is shown with fossilized shells, illustrating its formation from marine organisms.

Front

Calcium Carbonate Noun

---

[kal-see-uhm kahr-buh-neyt]

Back

Calcium Carbonate

---

A chemical compound with the formula CaCO3 that is the main component of limestone, marble, chalk, and shells.

---

Example: The image shows the molecular structure of calcium carbonate, highlighting its chemical composition with labeled atoms.

Front

Calcite Noun

---

[kal-sahyt]

Back

Calcite

---

A common rock-forming mineral made of calcium carbonate that is the primary component of limestone and fizzes with acid.

---

Example: Calcite crystals are shown here, which are made of calcium carbonate and are common in limestone.

Front

Weathering Noun

---

[weth-er-ing]

Back

Weathering

---

The natural process of breaking down rocks, soil, and minerals through contact with the Earth's atmosphere, water, and organisms.

---

Example: A river erodes soil and rock, showing how water breaks down materials over time.

Front

Physical Weathering Noun

---

[fiz-i-kuhl weth-er-ing]

Back

Physical Weathering

---

The mechanical process of breaking down rocks into smaller pieces without altering their chemical composition.

---

Example: Water freezes in rock cracks, expands, and breaks the rock apart.

Front

Chemical Weathering Noun

---

[kem-i-kuhl weth-er-ing]

Back

Chemical Weathering

---

The decomposition of rocks through chemical reactions, such as dissolving in acid, which changes their mineral composition.

---

Example: The image shows a rock surface affected by chemical weathering, where acids have dissolved minerals, changing its composition.

Front

Ooze Noun

---

[ooz]

Back

Ooze

---

A soft, muddy sediment on the ocean floor, often composed of the microscopic remains of organisms that can form limestone.

---

Example: The image shows ocean floor sediment, highlighting microscopic remains that form ooze.

Front

Precipitate Verb

---

[pri-sip-i-teyt]

Back

Precipitate

---

To form a solid substance from a solution due to a chemical reaction or a change in physical conditions.

---

Example: A solution forms a solid precipitate, showing a chemical reaction.

Front

Cave Noun

---

[kayv]

Back

Cave

---

A natural underground chamber, often formed by the chemical weathering and dissolution of limestone by acidic groundwater.

---

Example: The image shows a cave with stalactites and stalagmites formed by mineral deposition from dripping water.
