Continental Drift Worksheet: Place evidence on the map to support the theory of continental drift.

To solve this problem, we need to place the pieces of evidence listed in the legend onto the map provided. These pieces of evidence are used to support the theory of continental drift. Here's how we can approach this:

Step 1: Understand the Theory of Continental Drift

The theory of continental drift suggests that the continents were once joined together in a supercontinent called Pangaea and have since drifted apart over millions of years. Evidence for this includes:
- Fossils of similar species found on different continents.
- Matching geological features (e.g., mountain ranges).
- Similar rock types and structures across continents.

Step 2: Analyze the Legend

The legend provides the following categories of evidence:
1. Mesosaurus Reptile
2. Desert
3. Amphibians
4. Plateosaurus
5. Alpine Mountains
6. Tropical Plants
7. Igneous Rocks
8. Basalt Rocks
9. Phytosaur

Step 3: Research and Place the Evidence

We need to research where these pieces of evidence are found and then place them on the map. Below is a breakdown of where each piece of evidence should be placed:

#### 1. Mesosaurus Reptile
- Location: South America and Africa.
- Explanation: Mesosaurus fossils have been found in both South America and Africa, suggesting these continents were once connected.

#### 2. Desert
- Location: Sahara Desert (Africa) and Arabian Desert (Asia).
- Explanation: Deserts like the Sahara and Arabian Desert provide evidence of past connections between continents, as they share similar geological histories.

#### 3. Amphibians
- Location: Southern continents (South America, Africa, Antarctica, Australia).
- Explanation: Certain amphibian species are found in areas that were once part of Gondwana, supporting the idea that these continents were connected.

#### 4. Plateosaurus
- Location: Europe and North America.
- Explanation: Plateosaurus fossils have been found in Europe and North America, indicating a shared history before the continents drifted apart.

#### 5. Alpine Mountains
- Location: Europe and Asia.
- Explanation: The Alps in Europe and the Himalayas in Asia are part of the same tectonic activity, suggesting a historical connection.

#### 6. Tropical Plants
- Location: South America, Africa, and Australia.
- Explanation: Tropical plant species are found in regions that were once part of Gondwana, providing biological evidence for continental drift.

#### 7. Igneous Rocks
- Location: Widely distributed but notable in South America, Africa, and Antarctica.
- Explanation: Igneous rocks formed by volcanic activity can be traced back to when continents were connected.

#### 8. Basalt Rocks
- Location: Mid-ocean ridges and continental margins.
- Explanation: Basaltic rocks are common at divergent plate boundaries, which are key to understanding continental drift.

#### 9. Phytosaur
- Location: North America and Africa.
- Explanation: Phytosaur fossils have been found in both North America and Africa, supporting the idea that these continents were once part of the same landmass.

Step 4: Place the Evidence on the Map

Using the information above, place the symbols corresponding to each category on the map. For example:
- Use the symbol for "Mesosaurus Reptile" in South America and Africa.
- Use the symbol for "Desert" in the Sahara and Arabian regions.
- Continue this process for all categories.

Final Answer

The final map should have the symbols from the legend placed in the appropriate locations based on the research above. Here is a summary of the placements:

- Mesosaurus Reptile: South America and Africa.
- Desert: Sahara (Africa) and Arabian (Asia).
- Amphibians: South America, Africa, Antarctica, Australia.
- Plateosaurus: Europe and North America.
- Alpine Mountains: Europe and Asia.
- Tropical Plants: South America, Africa, Australia.
- Igneous Rocks: South America, Africa, Antarctica.
- Basalt Rocks: Mid-ocean ridges and continental margins.
- Phytosaur: North America and Africa.
