Students' Pangaea Puzzle worksheet illustrating the ancient supercontinent.

The image you provided is a puzzle depicting the continents as they were arranged during the supercontinent Pangaea. The task appears to be to reassemble these continents into their original configuration, forming Pangaea.

Step-by-Step Solution:

1. Identify the Continents:
- The labeled continents in the image are:
- Antarctica
- South America
- North America
- Australia
- Africa
- Arabia
- Greenland
- Europe
- India

2. Understand Pangaea:
- Pangaea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras (approximately 300 million years ago).
- It consisted of all the Earth's landmasses joined together into a single continent.
- Over time, due to tectonic plate movements, Pangaea broke apart and the continents drifted to their current positions.

3. Reassemble the Puzzle:
- The goal is to fit the continents back together as they were in Pangaea. Here’s how to do it:

#### Step 1: Place Africa at the Center
- Africa is a key continent in Pangaea because it was near the center.
- Position Africa horizontally in the middle of the puzzle.

#### Step 2: Attach South America to the West of Africa
- South America fits snugly against the western edge of Africa. The coastlines of both continents align perfectly when placed together.

#### Step 3: Add North America Above South America
- North America fits above South America, with its eastern coast aligning with the northern part of Africa and the western coast of Europe.

#### Step 4: Place Europe to the Northeast of Africa
- Europe fits to the northeast of Africa, completing the northern part of the supercontinent.

#### Step 5: Add Arabia to the East of Africa
- Arabia fits neatly against the eastern side of Africa.

#### Step 6: Position India Below Arabia
- India fits below Arabia, filling the gap between Arabia and the southern part of Asia.

#### Step 7: Place Australia Below India
- Australia fits below India, completing the southeastern part of Pangaea.

#### Step 8: Add Antarctica Below Africa
- Antarctica fits below Africa, completing the southern part of Pangaea.

#### Step 9: Place Greenland Between North America and Europe
- Greenland fits between North America and Europe, completing the northernmost part of Pangaea.

4. Final Configuration:
- When all the continents are correctly aligned, they should form a single, continuous landmass resembling Pangaea.

Explanation:

The alignment of the continents in this puzzle is based on the theory of continental drift, proposed by Alfred Wegener in the early 20th century. This theory suggests that the continents were once joined together and have since drifted apart due to the movement of tectonic plates.

Final Answer:

The solution involves fitting the continents together as follows:
- Africa at the center.
- South America to the west of Africa.
- North America above South America.
- Europe to the northeast of Africa.
- Arabia to the east of Africa.
- India below Arabia.
- Australia below India.
- Antarctica below Africa.
- Greenland between North America and Europe.

When assembled correctly, the continents will form the supercontinent Pangaea.

Boxed Final Answer:
