Why is the land surface rising in the Hudson Bay region of Canada? accelerated heat flow from the upper mantle rapid elastic rebound due to recent loss of ice slow viscous rebound in response to ice melting over 10,000 years ago tectonic uplift due to converging lithospheric plates None of the answers is correct.

Hudson bay is a large slat body of water in northeastern Canada has an area of 1,230,000 km2. It is considered a marginal sea in Arctic ocean. The southern extension of Hudson Bay is called James Bay. The Hudson bay consists of a polar climate. The Hudson Bay has many islands near the eastern coast. Due to the large constructal basin, the Hudson bay lies in the Canadian shield. Seismic data and deep drilling has shown that it consists of limestone, dolomite, and shale deposits. It has large clastic sedimentary rocks that overlie about 60 meters. During the Ordovician and the Silurian, the regular subsidence o this part of the Canadian shied formed the Hudson basin. The formation of his basin led to the accumulation of rock deposits within the center. The development of the extensive reef that formed a ring around the basin margin which later were tectonically uplifted as the basin subsided, this divided the basin into eastern and western parts.Thus, the rising of the Hudson basin due to the tectonic convergence of the lithospheric plate. The bay is associated with the basin located on the center of the Candian shield. The Canadian shield shows some mantle convection that occurred beneath. Based on the glacial isostatic data Laurentide ice sheet formed the large dome on the eastern and western side of the bay.
