Day 41: Shapes of Land
Land has different shapes, called landforms. A mountain is very high land with steep sides. A hill is raised land that is lower and rounder than a mountain.
A valley is low land between hills or mountains. A plain is wide, flat land. Cheaha Mountain, in east Alabama, is the highest point in the state.
Worked example: What is the low land between two mountains called?
- Low land between hills or mountains is a valley.
Worked answer: A valley.
Day 42: Bodies of Water
A body of water is a place where water collects. An ocean is a huge body of salt water. A lake is a large body of water with land all around it. A pond is like a lake but smaller.
A river is moving water that flows toward a lake or the ocean. An island is land with water all around it.
Worked example: What is the difference between a lake and an island?
- A lake is water with land all around it.
- An island is land with water all around it.
Worked answer: A lake is water surrounded by land; an island is land surrounded by water.
Day 43: Build a Landform Model
A model helps us see the shapes of land and water from above and from the side.
In a good landform model, a mountain is taller than a hill, a valley sits low between raised land, and water fills the lowest places.
Worked example: In a model, where should a river go: on top of a mountain or through a valley?
- Water flows downhill to low places.
- A valley is low land.
Worked answer: Through a valley.
Day 44: Reading a Map of Land and Water
A map is a flat drawing of a place seen from above. A map key, or legend, tells what the colors and symbols mean.
On many maps, blue shows water and green or brown shows land. A triangle may stand for a mountain, and a wavy blue line may stand for a river.
Worked example: On a map, a key shows a wavy blue line for River. What does a wavy blue line on the map stand for?
- Look at the key.
- Wavy blue line means river.
Worked answer: A river.
Day 45: Independent Check: Land and Water
Today you will answer on your own.
Use what you learned this week: landforms, bodies of water, models and map keys.
Worked example: What is land with water all around it?
- Remember the meaning of island.
Worked answer: An island.
