Mangrove trees are an important part of Florida's diverse ecosystem and are integral to the coastal intertidal zones where they grow. These plants also filter pollution. What impact would the removal of the Florida Mangrove have on the environment? A. The air quality would decline because there would be less plants to aid in the filtering of pollutants from the air we breathe.; B. There wouldn't be as much shade to help humans hide from the Sun.; C. Cheetahs would lose their hunting grounds.; D. The loss of the Florida Mangrove would not affect the environment because humans combat pollution before it becomes a problem.

Describe the difference between weathering and erosion. Give an example of each term based on a natural occurrence/phenomena.
Answers may vary, but should not deviate from: Weathering is the natural process that causes rock to break down over time. Erosion is the moving or shifting of those smaller pieces of broken rock by natural forces, such as wind, water or ice. (Example of erosion: When the tide pulls the sand further out into the ocean.; weathering: When rocks are sculpted by wind weathering.)

A gardener wants to determine which brand of fertilizer provides the most growth for his plants. He plans to follow a procedure which includes: 1. Divide the area to be planted into 4 equal quadrants; 2. Plant each section with the SAME type of seed; 3. Sprinkle each section with the same amount of a different type of fertilizer; 4. Water each section with the same amount of water each day for 2 weeks. **What should the gardener do next to improve the investigation?**
*Answers will vary, but should relate to*: Measure the the height of the plants in each section, and compare the results to determine which fertilizer provided the most growth.

Explain how Igneous, Sedimentary & Metamorphic rocks formed?
Igneous rocks are formed from melted rock deep inside the Earth. Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons. Metamorphic rocks formed from other rocks that are changed by heat and pressure underground.
