The water of which of the following seas is most saline?

  1. Black Sea

  2. Dead Sea

  3. Baltic Sea

  4. Red Sea
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

With 33.7% salinity, the Dead Sea is one of the world's saltiest bodies of water. The Dead Sea is landlocked and in the lowest valley on earth. All the minerals of the surrounding countryside get washed into one pool, which in turn gets baked by the sun. This concentrates the salts so much that the Dead Sea is 10 times as salty as the ocean.

The scandinavian countries are located in high latitudes. Parts of countries located in the same latitudes freeze during winter, but the ports located on the Norwegian coast do not freeze. 
This is the mainly due to the fact that __________________.

  1. Many small rivers drain to the sea

  2. There is a chain of volcanoes

  3. The North Atlantic Drift flows past the coast

  4. The Westerlies blow from the South West
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
The scandinavian countries are located in high latitudes. Parts of countries located in the same latitudes freeze during winter, but the ports located on the Norwegian coast do not freeze. 
This is the mainly due to the fact that the North Atlantic Drift flows past the coast.

The relatively warm waters of the North Atlantic Drift are responsible for moderating the climate of western Europe, so that winters are less cold than would otherwise be expected at its latitude. Water in the north Atlantic sinks because it is dense.
