Educational worksheet about natural landforms and features, featuring a matching activity and a labeled map.

To solve the problem, we need to match each physical feature of Earth with its corresponding description. Here is the solution:

Matching the Features:

1. bay - 9. large body of salt water partially enclosed by land
2. island - 3. piece of land surrounded by water on all sides
3. gulf - 4. inlet of a large body of water that extends into the land but is smaller than a bay
4. mountain - 5. opens up spaces that sell rocks and gases
5. plain - 7. lowland between hills or mountains
6. lake - 6. large inland body of water
7. valley - 8. lowland between hills or mountains
8. volcano - 5. opens up spaces that sell rocks and gases
9. ocean - 10. vast body of salt water

Explanation:

- Bay: A bay is a large body of water that is partially enclosed by land. It is larger than a gulf.
- Island: An island is a piece of land completely surrounded by water.
- Gulf: A gulf is an inlet of a large body of water that extends into the land but is smaller than a bay.
- Mountain: Mountains are tall landforms made of rock and soil, often with steep slopes.
- Plain: Plains are large areas of flat land, typically found in lowlands.
- Lake: A lake is a large body of water surrounded by land.
- Valley: Valleys are low-lying areas of land between hills or mountains.
- Volcano: Volcanoes are mountains that can erupt, releasing lava, ash, and gases.
- Ocean: Oceans are vast bodies of saltwater covering most of the Earth's surface.

Writing the Numbers on the Map:

After matching the features, you should write the corresponding numbers (1–10) next to each labeled feature on the map provided in the worksheet.

Final Answer:

Here is the matching in numerical order:
1. bay → 9
2. island → 3
3. gulf → 4
4. mountain → 5
5. plain → 7
6. lake → 6
7. valley → 8
8. volcano → 5
9. ocean → 10

Final Answer:
\boxed{9, 3, 4, 5, 7, 6, 8, 5, 10}
