Weathering and Erosion

Front

Ecosystem Noun

---

[ee-koh-sis-tuhm]

Back

Ecosystem

---

A biological community of interacting organisms and their physical environment, forming a complex and interconnected system.

---

Example: This image shows an aquatic ecosystem with plants, fish, and water, illustrating how organisms interact with their environment.

Front

Sediment Noun

---

[sed-uh-muhnt]

Back

Sediment

---

Small, naturally occurring pieces of rock, soil, or organic material broken down by weathering and transported by natural forces.

---

Example: Sediment layers shown in a cross-section illustrate how small particles are deposited over time.

Front

Rapids Noun

---

[rap-idz]

Back

Rapids

---

A section of a river where the current is very fast and turbulent due to a steep descent or obstacles.

---

Example: Rapids form when a river flows quickly over rocks, causing fast and turbulent water movement.

Front

Habitat Noun

---

[hab-i-tat]

Back

Habitat

---

The natural home or environment where an animal, plant, or other organism lives and obtains its essential resources.

---

Example: A pond habitat showing fish, plants, and other organisms living together.

Front

Endangered Species Noun

---

[en-deyn-jerd spee-sheez]

Back

Endangered Species

---

A species of animal or plant that is at a very high risk of becoming extinct in the near future.

---

Example: This image shows different endangered animals and their population numbers, illustrating the concept of endangered species.

Front

Ecology Noun

---

[ee-kol-uh-jee]

Back

Ecology

---

The scientific study of the relationships and interactions between living organisms and their physical and biological environment.

---

Example: The image shows rainforest layers, explaining how different plants and animals interact in their environment.

Front

Eddy Noun

---

[ed-ee]

Back

Eddy

---

A circular current of water running contrary to the main current, often creating a small, gentle whirlpool.

---

Example: The image shows an eddy forming around a rock, with arrows indicating the circular water flow.

Front

Deposition Noun

---

[dep-uh-zish-uhn]

Back

Deposition

---

The geological process where sediments, soil, and rocks are laid down or added to a landform or land mass.

---

Example: Sediments are deposited in layers at the bottom of a body of water, forming new land.

Front

Weathering Noun

---

[weth-er-ing]

Back

Weathering

---

The natural process that breaks down rocks, soil, and minerals through contact with the Earth's atmosphere and water.

---

Example: A river erodes soil and rocks, showing how water breaks down earth materials.

Front

Erosion Noun

---

[ih-roh-zhuhn]

Back

Erosion

---

The geological process in which earthen materials are worn away and transported by natural forces like wind or water.

---

Example: Wind moves sand and dust in deserts, showing erosion by carrying particles through the air.
