Questions and Answers

What natural process forms valleys between mountains or hills?

Erosion

How does the shape of valleys differ when formed by glaciers compared to rivers?

Glacier-formed valleys are U-shaped, while river-formed valleys are V-shaped.

What are coastal plains and how are they formed?

Coastal plains are lowlands next to seas or oceans, formed by the action of water.

Flashcards

What is a V-shaped valley?

A low-lying area of land between mountains or hills, formed by river erosion, with a characteristic V-shape.

What is a plain?

A flat and broad landform with little change in elevation, often formed by water, ice, or magma. Provides fertile ground for agriculture.

What is erosion?

The process of wearing down rocks and soil by natural forces like water, wind, or ice.

What are coastal plains?

Plains located near a sea or ocean, typically lowlands that stretch parallel to the coastline.

Study Notes

Valleys

Valleys are low-lying landforms between hills or mountains.
Valleys form due to erosion, the natural process of water wearing down rocks and soil.
Water flowing down mountains carves V-shaped channels.
Glaciers create U-shaped valleys.
Valleys usually have pleasant climates, making them good places to live.
Water from rivers in valleys provides resources for human settlements.

Plains

Plains are broad, flat landforms with little elevation change.
Plains are made by factors such as water, ice, and magma.
Plains are excellent farmland because the soil is fertile.
Plains near seas/oceans are called coastal plains.
Plains made by rivers, wind and erosion are called erosional plains.
Plains cover about a third of Earth's land area.

Plateaus

The text refers to a plateau, the Lasithi plateau in Crete Island, Greece, as an example of flat land.
The sides of plateaus in picture B are called cliffs.
