Revolt · Accepted Answer

The United States and Canada cooperate to protect shared resources such as the Great Lakes by reducing pollution, improving wastewater treatment, and monitoring water quality. They also work together to reduce air pollution and greenhouse-gas emissions through environmental agreements and cleaner energy programs. These efforts help protect ecosystems and prevent future environmental problems.

Question 7

What is a glacier? How could a massive chunk of ice carve out valleys and create lakes? Explain what glaciation means and identify an example of a lake that was formed by glacial processes.

Revolt · Accepted Answer

A glacier is a large mass of ice that forms on land and moves slowly under its own weight. As a glacier advances, rocks and sediment frozen into its base scrape and grind against the ground, carving valleys and creating depressions. When the ice melts, water fills these depressions and forms lakes. Glaciation is the process by which glaciers shape and erode the land. The Great Lakes, such as Lake Michigan and Lake Superior, were formed largely by glacial processes.

Question 8

Describe two important industries in the United States. What natural resources support these industries? Why are these natural resources important to the United States?

Revolt · Accepted Answer

Two important U.S. industries are manufacturing and agriculture. Manufacturing uses natural resources such as iron ore, copper, petroleum, natural gas, coal, and water to produce vehicles, machinery, chemicals, and other goods. Agriculture depends on fertile soil, freshwater, sunlight, and land for growing crops and raising livestock. These resources are important because they provide food, energy, jobs, and materials for products, while also supporting trade and the national economy.

Question 9

Describe each of the natural events that commonly affect the United States and Canada. We discussed five of these natural events in this lesson, including tornadoes, earthquakes, volcanic eruptions, blizzards, and hurricanes. Are any of these events common in your region?

Revolt · Accepted Answer

Tornadoes are rapidly rotating columns of air that extend from thunderstorms to the ground, and they are especially common in the Great Plains and Midwest. Earthquakes occur when movement along faults releases energy in Earth's crust, with many occurring along the West Coast. Volcanic eruptions happen when magma, ash, and gases escape from a volcano, especially in the Pacific Northwest and Alaska. Blizzards are severe snowstorms with strong winds and low visibility, common in northern areas and the Great Plains. Hurricanes are powerful tropical storms that form over warm ocean water and can affect the Atlantic and Gulf coasts. In my region, the most common of these events are severe thunderstorms and occasional tornadoes; the others are less common.
