Step-by-step solution for: Sixth Grade Space Worksheets
Let's solve the problem step by step based on the image you described. The worksheet titled "Our Earth" asks students to match descriptions with the correct layer of the Earth, using a diagram showing the four main layers: Inner Core, Outer Core, Mantle, and Crust.
Here are the descriptions provided in the boxes:
---
> This layer makes up two-thirds of the Earth’s mass and is about 1,800 miles deep. It is made up of a thick, solid, rocky substance, with portions that melt enough to flow.
- Analysis:
- "Two-thirds of Earth’s mass" → This is a key clue. The Mantle makes up about 70% of Earth’s mass.
- "About 1,800 miles deep" → The mantle extends from about 30 km (crust) to ~2,900 km depth — so 1,800 miles (~2,900 km) is roughly accurate.
- "Thick, solid, rocky substance with portions that melt enough to flow" → This describes the mantle, which is mostly solid but has regions where rock flows slowly due to high heat and pressure.
✔ Correct Layer: Mantle
---
> Surprisingly, this layer is thought to be solid, even though it is farthest from the surface and beneath what's thought to be molten lava.
- Analysis:
- "Farthest from the surface" → That would be the inner core.
- "Thought to be solid" → Yes, the inner core is solid despite being extremely hot, due to immense pressure.
- "Beneath what's thought to be molten lava" → The outer core is molten (liquid iron/nickel), and the inner core is solid and lies beneath it.
✔ Correct Layer: Inner Core
---
> This layer of the Earth is hard and composed of different minerals. It is the thinnest layer.
- Analysis:
- "Hard" and "composed of different minerals" → Describes the crust.
- "Thinnest layer" → The crust is indeed the thinnest layer (only 5–70 km thick).
✔ Correct Layer: Crust
---
> At a depth of 3000 miles beneath the surface, this layer is believed to be made of super-heated liquid molten rock. This lava is thought to be made of mostly iron and nickel.
- Analysis:
- "3000 miles beneath the surface" → 3000 miles ≈ 4800 km. The outer core starts at about 2,900 km and goes to 5,150 km.
- "Super-heated liquid molten rock" → The outer core is liquid.
- "Made of mostly iron and nickel" → Correct composition of the outer core.
✔ Correct Layer: Outer Core
---
| Description | Correct Layer |
|-----------|---------------|
| 1 | Mantle |
| 2 | Inner Core |
| 3 | Crust |
| 4 | Outer Core |
---
- Crust: Thinnest, hard, mineral-rich layer.
- Mantle: Thick, rocky, makes up most of Earth's mass.
- Outer Core: Liquid, made of iron and nickel, generates Earth's magnetic field.
- Inner Core: Solid, dense, hottest part, under extreme pressure.
✔ Match each description to its corresponding layer as above.
