The theory
of a land bridge between South America and Africa as an explanation for similar
fossils on the two continents is not supported today because there are
no remnants of the bridge in the Atlantic Ocean.
<span>A </span>land
bridge, in biogeography<span>, is an </span>isthmus<span> or wider land connection between otherwise separate areas, over which
</span>animals<span> <span>and </span></span>plants<span> <span>are able to cross and </span></span>colonize<span> <span>new lands. A land bridge can be created by </span></span>marine regression<span>, in which </span>sea
levels<span> <span>fall, exposing shallow, previously submerged sections of </span></span>continental shelf<span>; or when new land is created by </span>plate tectonics<span>; or occasionally when the sea floor rises due to </span>post-glacial rebound<span> <span>after an </span></span>ice
age.

Answer:
The landform that provides the trees/lumber that is used to power Quebec and Ontario's economy is the Canadian Shield.
Explanation:
Quebec and Ontario are Canadian provinces. They are the top two or close to the top in pretty much every department in Canada. They have a lot of natural resources, they have the highest populations, their economies are the most developed, etc. One natural resource that is extremely important for the economy of these two is the lumber or rather the forests.
The Canadian Shield, which is the most dominant landform in Canada, occupies almost all of the territories of these two provinces. It is the landform that actually provides all of the trees/lumber. The forests are boreal, and the majority of them made up of coniferous trees, though in the southern parts there are multiple species of trees that are deciduous, like Canada's trademark tree - the maple, which is also a tree that brings in a lot of profit to these provinces and the country as a whole.
Answer:
Mining is important to the economy of Ethiopia as a diversification from agriculture. Currently, mining comprises only 1% of GDP. Gold, gemstones (diamonds and sapphires), and industrial minerals are important commodities for the country's export-oriented growth strategy. Tantalum mining has also been profitable.
Hope this is helpful to you.
