Good morning! I appreciate your honesty in using this service only to check your work. Now, let's dive into the explanations for each question:
1. Which of the following did the Antarctic Treaty do for Antarctica?
The correct answer is D. It set Antarctica aside for scientific research.
To determine this, you can access your course materials or textbook and review the content related to the Antarctic Treaty. The Antarctic Treaty is an international agreement that was signed in 1959. It prohibits any military activity, mineral mining, and nuclear testing in Antarctica. Instead, it promotes scientific research and encourages cooperation among nations. By referring to the text or notes that cover this topic, you should be able to find the information confirming that the treaty was established to protect Antarctica for scientific purposes.
2. What is pack ice?
The correct answer is D. large, seasonal masses of ice that form and float on water.
To understand the meaning of pack ice, you can refer to your course materials or a reliable source that explains glacial formations. Pack ice refers to the masses of ice that develop and float on the surface of the water. These ice formations are usually found in the polar regions and can be massive in size, often covering large areas. Consulting your textbook or online resources about glaciers, ice, and polar regions can provide you with a comprehensive explanation of pack ice.
3. Why is the ozone layer in Antarctica significant?
The correct answer is A. It is getting thinner, allowing more harmful ultraviolet rays to reach Earth.
To comprehend the significance of the ozone layer in Antarctica, it's useful to learn about ozone depletion and its implications. The ozone layer is a protective layer in the Earth's atmosphere that absorbs much of the Sun's ultraviolet (UV) radiation. However, over the years, certain chemicals, primarily chlorofluorocarbons (CFCs), have depleted the ozone layer, resulting in a thinning of this protective shield. This phenomenon is most pronounced over Antarctica, leading to what is known as the "ozone hole." The thinning ozone layer allows more harmful UV rays to penetrate and reach the Earth's surface. By referring to relevant resources, such as your textbook or trusted scientific websites, you can find detailed explanations about the significance of the ozone layer in Antarctica and its impact on the environment.
Remember, understanding the context and background of the topics covered in your lessons will contribute to your overall comprehension and learning experience. If you have any more questions or need further clarification, feel free to ask!
