A fold shaped like an elongate trough is an<u> A. Anticline</u>.
<h3>What is an elongate trough?</h3>
An elongate trough forms the deepest part of a surface undulation with a subparallel trend to an adjacent trough.
An anticline is an arch-like shape with its oldest beds at its core, curved upward. An anticline is an inverse of a syncline, which is curved downward.
A. Anticline
B. Basin
C. Dome
D. Syncline
Thus, a fold shaped like an elongate trough is an<u> A. Anticline</u>.
The upliftment weathering hypothesis suggests that the formations of the uplifted terrains the global climate into an icehouse state and the main factor that influences the global state of the chemical weathering are the global rainfall and the high temperatures, like the rocks in the tropical areas, are exposed to the dry and hot weather conditions.
<u>Similar to that of the cold areas the rocks are exposed to the cold and first action and the interaction of the moisture contents that transform the minerals in the rocks. Which are ongoing processes through the impacts of the oxidation and hydrolysis.
</u>
The formation of the acidic contents in the rocks ios created by the impacts of these temperatures on the rocks mass. The carbonization that is an atmospheric process of the addition to carbon contents to the air and impacts the limestone and the chalk rocks.
