The process where rocks and minerals are broken down into smaller pieces by things like wind, water, and temperature changes.

Long, narrow islands made of sand that sit just off the coast and help protect the mainland from big waves and storms.

Sandy or pebbly areas along the edge of a body of water, like an ocean, lake, or river, where people often go to relax and swim.

A landform created where a river meets a larger body of water, like a sea or ocean, and drops off the sediment it’s carrying, forming a fan-shaped area.

Hills or mounds of sand formed by the wind, often found near beaches or deserts.

The process where soil, rocks, or sand are worn away by forces like wind, water, or ice.

Flat land next to a river that can get covered with water when the river overflows, often creating rich soil.

Fine, dusty soil that has been blown by the wind and forms thick layers on the ground.

Wetlands that are often covered with shallow water and have lots of grasses and plants, providing homes for many animals.

Piles of rocks and dirt left behind by glaciers as they move or melt.

Flat areas made of sediment (sand, gravel) that were spread out by water flowing from melting glaciers.

Large, flowing bodies of water that move across the land from higher to lower areas, often emptying into oceans or lakes.

When rocks are broken down or dissolved by chemicals in rain, water, or air, changing their composition. For example, rain can make certain rocks crumble.

When wind, water, or ice drop off bits of rock, soil, or sand in a new place, building up layers over time.

The process where soil, rock, or sand is worn away and moved to another place by forces like wind, water, or ice.

The breaking down of rocks into smaller pieces without changing what they’re made of. This happens through things like freezing and thawing or roots growing into cracks.

The process of rocks being broken down into smaller pieces by natural forces like water, wind, or temperature changes.

The solid rock layer found beneath soil and loose rocks on the Earth’s surface.

A layer of soil that is different from the layers above or below it. Soil has different horizons that form over time.

Dark, organic material in soil made from decayed plants and animals. It’s important for keeping soil healthy and full of nutrients.

The top layer of the Earth where plants grow, made of minerals, organic material, water, and air.

The uppermost layer of soil that is rich in nutrients and where most plants grow their roots.

Unit 3 - W.E.D

6th Grade Unit 3- Weathering, Erosion and Deposition

Question	Answer
Weathering	The process where rocks and minerals are broken down into smaller pieces by things like wind, water, and temperature changes.
Barrier islands	Long, narrow islands made of sand that sit just off the coast and help protect the mainland from big waves and storms.
Beaches	Sandy or pebbly areas along the edge of a body of water, like an ocean, lake, or river, where people often go to relax and swim.
Delta	A landform created where a river meets a larger body of water, like a sea or ocean, and drops off the sediment it’s carrying, forming a fan-shaped area.
Dunes	Hills or mounds of sand formed by the wind, often found near beaches or deserts.
Erosion	The process where soil, rocks, or sand are worn away by forces like wind, water, or ice.
Floodplain	Flat land next to a river that can get covered with water when the river overflows, often creating rich soil.
Loess	Fine, dusty soil that has been blown by the wind and forms thick layers on the ground.
Marshes	Wetlands that are often covered with shallow water and have lots of grasses and plants, providing homes for many animals.
Moraines	Piles of rocks and dirt left behind by glaciers as they move or melt.
Outwash plains	Flat areas made of sediment (sand, gravel) that were spread out by water flowing from melting glaciers.
Rivers	Large, flowing bodies of water that move across the land from higher to lower areas, often emptying into oceans or lakes.
Chemical weathering	When rocks are broken down or dissolved by chemicals in rain, water, or air, changing their composition. For example, rain can make certain rocks crumble.
Deposition	When wind, water, or ice drop off bits of rock, soil, or sand in a new place, building up layers over time.
Erosion	The process where soil, rock, or sand is worn away and moved to another place by forces like wind, water, or ice.
Physical weathering	The breaking down of rocks into smaller pieces without changing what they’re made of. This happens through things like freezing and thawing or roots growing into cracks.
Weathering	The process of rocks being broken down into smaller pieces by natural forces like water, wind, or temperature changes.
Bedrock	The solid rock layer found beneath soil and loose rocks on the Earth’s surface.
Horizon	A layer of soil that is different from the layers above or below it. Soil has different horizons that form over time.
Humus	Dark, organic material in soil made from decayed plants and animals. It’s important for keeping soil healthy and full of nutrients.
Soil	The top layer of the Earth where plants grow, made of minerals, organic material, water, and air.
Topsoil	The uppermost layer of soil that is rich in nutrients and where most plants grow their roots.
