A peninsula is an area of land (like Florida) that hangs off of land like an island but one part's connected. A tundra is wide open, flat land, like the Alaskan Tundra. A mountain range is a long string of mountains side by side like the Appalachians. And for mountain barriers (I'm not sure I fully understand but) it seems like theirs more dew and wind for example on one side of the mountain and the others the opposite because the mountain blocks it (not completely sure bout the mountain part but i think its right!).
