Savannahs are tropical rain forests.

Answer

**Step-by-Step Solution:**

1. **Understanding the Terms:**
- Define what savannahs are. Savannahs are grassland ecosystems characterized by the trees being sufficiently small or sparse to allow sunlight to reach the ground, promoting the growth of grasses.

2. **Defining Tropical Rainforests:**
- Tropical rainforests are dense forests found in tropical regions, known for high rainfall, high humidity, and rich biodiversity. They typically have a closed canopy formed by tall trees.

3. **Comparing Savannahs and Tropical Rainforests:**
- Savannahs receive less rainfall compared to tropical rainforests. While tropical rainforests can receive over 2000 mm of rain annually, savannahs receive between 500 to 1500 mm.
- The vegetation in tropical rainforests is dense and diverse, whereas savannahs have a mix of grasslands and scattered trees.

4. **Soil Fertility:**
- The soil in tropical rainforests is generally very fertile due to the decomposition of organic matter. In contrast, savannah soils can be less fertile and may vary depending on the specific region.

5. **Conclusion:**
- Based on the differences in rainfall, vegetation, and soil, the statement "Savannahs are tropical rain forests" is false. Savannahs are distinct ecosystems that do not fit the criteria of tropical rainforests.

**Final Answer:**
The statement is false. Savannahs are not tropical rainforests; they are a different type of ecosystem characterized by grasslands and sparse tree growth.
