What do the black lines mean on this map?
Red dots= active volcanoes
yellow= the plates
please help!!!

Answer 1

They're continental plates (plate tectonics). See how it says "Nazca Plate" and "Pacific Plate"? The meeting of the Eurasian Plate & Indo-Australian Plate are what caused the title wave in Indonesia a couple years ago.

Answer 2

The black lines represent Tectonic Plates.

Answer 3

Depends on how it's used and the type of map. It might be a footpath, trail, or dirt road, but probably more commonly it's used to show a disputed boundary, like between countries that haven't quite figured out the border or when one country has declared independence but hasn't gained international recognition yet.

Answer 4

Well, see, the Earth is really God's baseball, and those are the seams God uses for throwing that universally-famous curve ball...

Seriously, though, the black lines do indeed mark the plate boundaries. Glad to see a consensus here on that!

Answer 5

The black lines represent the edges of the tectonic plates.

Answer 6

The black lines mark the plate boundaries. The yellow marks where dry land is, not where the plates are.

Answer 7

Yello is not the plates, but land. The black lines show the plates.

Answer 8

looks like crack(fault lines) where there is a chance that they may go over or under each other and cause tsunamis or earthquakes--the earth ain't getting any younger.

Answer 9

the edges of the plates

Answer 10

demarkation of the plates
