St. Lawrence Lowlands
The St. Lawrence lowlands is located in the southern area of Quebec and Ontario. The region has many hills and slopes instead of flat plains. It consist of the five great lakes which are lake Erie, lake Michigan, lake Huron, lake Ontario and lake Superior. The lowlands is also dominated by the Monteregian Hills, a series of isolated mountains stretching 20 km wide from Montreal to the Appalachians. The lowlands have a very dry, humid climate of hot summers because the great lakes provides moisture in the air and it is the only landform region closest to the equator. July tends to be the hottest month with temperatures reaching above 20 degrees Celsius and January tends to be the coldest month with temperatures reaching below 20 degrees Celsius. The lowlands contain five forests which are the Deciduous, Carolinian and Mixed forest located in the western and central area of the lowlands as well as high and mid boreal forest in the eastern area of the lowlands. The deciduous forest and the mixed forest contain most of the vegetation in the lowlands.
Limestone and Sandstone
The St. Lawrence lowlands contains Paleozoic sedimentary rocks such as limestone and sandstone ranging from 480 to 520 million years ago. Tile manufactures can benefit from that because they could use those minerals to create limestone and sandstone tiles for homeowners. Furthermore, in some places they charge around 60 to 80 dollars for raw limestone and 100 to 300 dollars for sandstone, however the lowlands offer them for free allowing tile manufacturing companies to save money which is another benefit.
Most of the St. Lawrence lowlands is covered underneath with clay especially under Champlain Sea. The clay deposit is as thick as 60 m along the northern side close to the glacier margin and it progressively becomes thinner. Tile manufactures can take advantage of the clay and use it to create structures such as clay roofs. However, there is one problem, when it rains or snows the clay becomes unstable and sometimes subsides, so during winter the clay may not be in the best condition, but during the summer the clay will return into its original state.
There are two natural disasters that may occur in the St. Lawrence lowlands which are landslides and floods for the following reasons. To begin with, most of the lowlands are on a slope meaning most of the land is tilted or on an angle and when it begins to rain heavily the soil becomes loose or saturated resulting in a land slide or a vibration of an earthquake can also cause a landslide, but earthquakes rarely occur on the lowlands. Moreover, during the summer the temperatures can rise over 20 degrees Celsius causing a huge amount of water to evaporate from the great lakes. Eventually, all that water vapour will condensate into clouds. However, since the heat caused a lot of water to evaporate that will cause a high level of precipitation which results into a flood. If the lowlands didn't consist of large bodies of water, flooding wouldn't be a problem because there wouldn't be a high amount of water heading into the atmosphere, but that will cause a drought.
