What land form is represented by the solid dark area on the map ? a) a continent b) an island c)a peninsula d)an isthmus

Option (D)

Explanation:

Isthmus refers to the tapering strip of land that connects two bigger landmasses. This narrow land occurs where there is the presence of the seas on both sides. For example, Isthmus of Kra that connects the peninsular Malaysia and the southern part of Thailand.

This type of landforms are generally formed near the seas and they can be formed by volcanic activities, that create island chains by obstructing the channel and accumulating sediments. The Isthmus of Panama formed in this way that is shown in the given image.

An isthmus can also form due to the lowering of sea level because it will expose more of its land area above the water surface.

Hence, the correct answer is Option (D).

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.  

(d). gave voting rights to free african americans and white women.
