The correct answer is: C: two and a half years. As a mater of fact, it started in May 1804 and lasted until September 1806. This expedition, also called Corps of Discovery Expedition was the first American expedition to cross what is now the western portion of the United States. Expedition was ordered by president Thomas Jefferson shortly after the Louisiana Purchase in 1803. The goals were to <span>explore and map the newly acquired territory, find a practical route across the Western part of the continent, and establish an American presence in this territory.</span>
Answer:
The intermediate magma has a heterogeneous structure, since it has a part of Silice, approximately 50-60% to be more exact.
When it turns into lava, it produces rocks like the Andesite and, in the opposite case of its crystallization, it forms rocks like the Diorite.
A comparison of felsic magma is much more viscous.
It is important to clarify that this magma is a type of primary magma, that is to say that they are magmas formed from the fusion of the rocks of the mantle or the crust.
Explanation:
The fusion of these rocks are what would give rise to the intermediate magma, this intermediate magma is a primary magma, like the mafic and felsic.
The primary magmas unlike the derived magmas is the origin or the reason for how they are formed, which is what we write above, derived magmas usually form differently since they are the product of the evolution or changes that magmas undergo primary
It would have effects on humans because it would Create widespread beach and cliff erosion, damaging coastal property and infrastructure. Make flood insurance unaffordable and unviable. Lead to salt-water intrusion in coastal aquifers, accelerating corrosion of waste- and storm-water drainage systems and affecting water quality and water resources.
Tectonic landform, any of the relief features that are produced chiefly by uplift or subsidence of the Earth’s crust or by upward magmatic movements. They include mountains, plateaus, and rift valleys.
