Factors that Regulate the Climate

Houston is close to 30 degrees N latitude, in the mid latitudes. It is flat and about 45 miles inland from the Gulf of Mexico. It is very humid much of the year due to its proximity to the Gulf of Mexico. The prevailing winds tend to be either from the N, when a a front comes down from the interior of the continent or from the S due to heating and cooling of the Gulf as compared to the land. Houston is lush due its proximity to the Gulf of Mexico.

Geology

Tectonic Plate Boundaries Near Dhaka

Dhaka is on the Indian Plate and is 183.4 km (113.96) away from the Northern plate boundary.

Rocks that Underlie Dhaka

There is a large deposit of sedimentary rocks lie under Dhaka, Bangladesh. This is most likely because of how close it is to the tectonic plate boundary where the two plates are colliding and rising to make the Himalayan Mountains. In Bangladesh sediments eroded from the Himalayas rolled down the mountains creating deltas in the land, which is now filled with water. This water is the main reason for there being sedimentary rocks under Dhaka, because water is needed for the sediments to be deposited, compacted, and cemented. This is why Dhaka's geology is so closely related to the tectonic plate it sits on.
