Chapter 5: Land and Water
Lesson #1: Earth’s Land

2. Vocabulary Landform: different shapes of Earth’s land Mountain: high
Hill: short
Plain: flat and wide
Valley: low land between mountains

3. 3 layers of Earth Crust: Earth’s outer layer.
Mantle: Earth’s middle layer.
Core: Earth’s deepest and hottest layer.

4. Earth Layers There are _____ main layers inside Earth?
Which layer can people live? __________
Which layer has hot lava? ________
Which layer is the thinnest? __________
Which layer is the thickest? __________
Which layer has two parts? __________
What are these two part? 1) ___ 2) _____

5. Map & Globe Map: flat - shows where land and water are on Earth.
Globe: sphere / ball
It is a model of Earth.
It is a map of Earth in the shape of a sphere or ball.

6. Continents & Oceans Continent: Big piece of lands
Island: small piece of lands
* Both Continents & Islands are surrounded by oceans/water.

7. Oceans 1. Arctic Ocean 2. Atlantic Ocean 3. Indian Ocean
4. Pacific Ocean
5. Southern Ocean
Continents
1. Africa
2. Antarctica
3. Asia
4. Australia
5. Europe
6. North America
7. South America

Ch.5/lesson #2: Earth’s Water

9. Vocabulary Fresh Water: water that is not salty
- found in lakes, ponds, rivers & streams
Ocean: A large body of salt water.
- where you found most of Earth’s water
Ocean covers ¾ of Earth
Most living things can only drinks ___________
Can people drink ocean water? ( Yes/No )

10. Why is water important? All living things need water to live & survive
Human Animals Plants
- drink drink grow and stay
- wash hands wash body health
- clean dishes live/home make their own food
- swim

11. Human vs. Earth Human Body Earth ocean / water
- ¾ of Earth is covered by
ocean / water
- human body consist 70% of water

12. Ch.5/lesson #3: Changes on Earth
Science Final Review
Ch.5/lesson #3: Changes on Earth

13. Vocabulary Earthquake: A shake in Earth’s crust.
- can cause great damages
- change the shape of land quickly
Volcano: an opening in Earth’s mantle and crust.
- A very hot, thick liquid (lava) comes
out  turn into solid rocks after it
cools down.

14. Vocabulary
Flood: water that flows over land and cannot easily soak into the ground.
- When a lot of rain falls quickly
- Change the shape of land quickly
- People build houses on stilts to keep them safe from flood
Landslide.: sudden movement of soil from higher to lower ground
Change the shape of land quickly
Heavy rain and melting snow can
cause landslides.

15. Slow changes on Earth Water Wind Fast moving water can wear away rock
water (warm weather)  ice (cold weather)
can cause the rocks to crack open
Wind
Strong winds blow sands and carry away soil.
The surface of the land or rock changes shape.
weathering- things like rock or wood changes its shape or color over time
condition (rain, sun, wind)
Erosion- gradual removal rock or soil by river, sea or weather.

16. Chapter 6: Earth’s Resources Lesson #1: Rocks and Minerals
Science Final Review
Chapter 6: Earth’s Resources
Lesson #1: Rocks and Minerals

17. Vocabulary
Natural resource: material from Earth that people use in daily life. (which ones are living vs nonliving?)
Water rocks air
Animals plants

18. Rocks nonliving part of Earth most rocks are hard Inukshuk
have different shapes, sizes, color and textures (how you feel)
cover the surface of Earth
found from top of a mountain, to below city streets, grass, soil and the bottom of the ocean
people use rocks as tools
made of one or more minerals

19. Minerals Bits of rock and soil that help plants and animals grow.
a nonliving part of Earth.
make the rocks shine and sparkle.
formed in the ground million years ago.
Uses of Minerals:
Graphite magnetite fluorite turquoise

20. Rocks vs. Minerals Same: - nonliving parts of Earth
- formed in the ground over millions of year
Different: Rocks Minerals
- tools nutrients for plants to grow
- make rocks shine

21. Science Final Review
Ch.6/lesson #2: Soil

22. Soil a mix of tiny rocks and bits of dead plants and animals.
allow plants to grow.
silt- tiny pieces of broken rock in soil.
have different colors and textures
clay soil topsoil sandy soil
darker color lighter color
(holds more water)
where plants grow best

23. How is soil form?
Over time, rocks and minerals break down into smaller pieces.
Decompose: when plants and animals die
( the dead body parts begins to rot away  decompose)
mushrooms  help break down the dead plants
Nutrient that were once in living things become part of the soil.
( nutrients  make the soil healthy for the plants)

24. How is soil form? compost pile- a mix of soil and parts of rotting
plants and animals.
- show how things decompose in the soil.
* topsoil: best for growing plants
has mushrooms
has rotting plant and animal parts
* subsoil: beneath topsoil
