Glaciation of Southern Ontario
1) Continental glaciation has had a great effect
on Southern Ontario
2)There are two major landforms in S.O. (Can.
Shield, GLSLL)
3)Glaciers moving south acted like a huge
conveyor belt pick up soil/debris in the Shield
and deposited the material in the GLSLL
(Where it is warmer)
Shield
 Pockets of the Shield filled with muddy
glacial water
 Sediment eventually settle out in the bottom
of pond
 Over time the ponds dry up and leave behind
Lacustrine Plains Good for Farming
Great lakes St. Lawrence Lowlands
 Features of the lowlands are depositional not
erosional
o Drumlins, Eskers, Oak Ridges Moraine
 There are some erosional features
o Deep river valleys carved from glacial melt
water (Don Valley, Humber Valley)
