Question

1. which statement about the element carbon (c) is true? there is too much carbon on the earth. there is not enough carbon on the earth. carbon does not exist on earth and must be mined elsewhere. carbon cycles through earths systems.

Explanation:

To determine the true statement about carbon, we analyze each option:

• "There is too much carbon on the Earth" is false as carbon is recycled and balanced in Earth's systems.
• "There is not enough carbon on the Earth" is false because carbon is abundant and cycles through systems.
• "Carbon does not exist on Earth and must be mined elsewhere" is false since carbon is naturally present in Earth's systems (e.g., in living organisms, atmosphere, rocks).
• "Carbon cycles through Earth’s systems" is true as the carbon cycle involves movement through the biosphere, atmosphere, hydrosphere, and geosphere.

Answer:

The option "Carbon cycles through Earth’s systems" (the left - most option among the four, or the fourth option in the vertical list as per the image)
