Geology of the Baltic Sea

Why do we associate the Swedish coasts with bare, steep rocks and with fiords, while the Polish beaches are built of soft sand and cliffs? Who or what had ‘dug ‘ the Baltic basin? Where the amber comes from? These and other questions will be answered during the class on the Baltic Sea geology. We will use microscopes to have a closer look at different types of rocks and to compare their structure. We will check what happens if we pour the hydrochloric acid on a rock and find out why it is good to sometimes take a magnet for a walk to the beach.
