true or false? there is nothing we can do to help prevent soil erosion. only scientists and farmers can work on solutions.
○ true
○ false

Explanation:

Question about terra preta:

• Terra preta is known as dark soil (due to high charcoal content).
• It is a mixture that includes burned organic matter (not just soil and straw, but the key is its composition with charcoal and nutrients) and is full of nutrients and charcoal.
• It is not unhealthy or depleted; in fact, it's highly fertile. So the correct options are "dark soil", "mixture of burned soil and straw" (more accurately, burned organic matter, but this option is closest), and "full of nutrients and charcoal". The "unhealthy, depleted soil" is incorrect.

Preventing soil erosion is a collective effort. Actions like planting trees, using cover crops, reducing overgrazing, and proper land management can be done by individuals, communities, not just scientists and farmers. So the statement is false.

Answer:

• dark soil
• mixture of burned soil and straw
• full of nutrients and charcoal
