This medium-level worksheet has students fill in blanks, and match items from two columns to practice earth's layers skills.
It includes 10 questions across 2 sections for focused practice.
Style:
Earth's Layers
Part A: Fill in the Blank
Write the missing word or number on each line.
1. The outer core is the only layer of Earth that is completely liquid.
2. Earth's crust is made mostly of rock and minerals, not metal.
3. The mantle contains a soft, slowly flowing zone called the asthenosphere.
4. Iron and nickel are the two main metals found in both the outer core and inner core.
5. The rigid top part of the mantle and the crust together form the lithosphere.
6. Continental crust is mainly composed of a lighter rock called granite.
7. The inner core reaches temperatures of about 5,000 degrees Celsius.
8. The mantle makes up roughly 84 percent of Earth's total volume.
9. Oceanic crust is thinner but denser than continental crust because basalt is heavier than granite.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Crust
→ Thin outer shell of rock where all living things exist
Liquid layer of molten iron that generates Earth's magnetic field
Mantle
→ Thickest layer made of hot rock that flows very slowly
Thickest layer made of hot rock that flows very slowly
Outer core
→ Liquid layer of molten iron that generates Earth's magnetic field
Solid ball of iron and nickel at Earth's center under extreme pressure
Inner core
→ Solid ball of iron and nickel at Earth's center under extreme pressure
Thin outer shell of rock where all living things exist
