b. the ancient rock of the Canadian shield covers about one fourth of Canada
c. the Mississippi drainage basin is the firth largest in the world
d. the most geologically active region of north America is found along the west coast OR B not sure
The correct answer is - C. The most geologically active region of North America is found along the West Coast.
The West Coast of North America is by far the most geologically active region on the continent. It is part of the ''Ring of Fire''. The west has boundaries of the North American tectonic plate and the Pacific tectonic plate which causes lot of geological activity in the region. Earthquakes are a common occurrence in this part and a big rift valley stretches through California and it is getting bigger and bigger with time. The biggest volcano nowadays is found in this region, more specifically under the Yellowstone National Park in the northwestern part of the United States.
Oolitic limestones form in a shallow marine environment. Oolitic limestones are composed of small, rounded, and often concentrically layered grains known as ooids.
The option (A) is correct.
These ooids form in shallow, warm, and clear marine waters, typically in tropical or subtropical regions. They precipitate from calcium carbonate that has been chemically dissolved in the water. Fossiliferous limestones, on the other hand, may form in various marine and non-marine environments and contain the preserved remains of ancient organisms.
Crystalline limestones can also form in different settings and are characterized by the presence of mineral crystals. However, oolitic limestones specifically indicate a shallow marine origin.

C)

D)
a decreased area of wilderness used to produce drugs.
The correct answer is - A) an increase in damage to sensitive ecosystems.
In the areas in Latin America where the drug production and drug trafficking are high, the environment is taking a major blow, and there's a lot of damage done to the sensitive ecosystems. For the production of drugs first is needed the raw material, which in Latin America is mostly cannabis and coca. In order to produce these plants and profit from them, the drug lords need a lot of agricultural land, and they obtain it by destroying parts of the rainforests in general. By destroying parts of the rainforests they are inflicting very big damage to the ecosystems, and they put lot of species in the endangered list because they destroy their habitat.
