Wolves are a predator, meaning they keep the cattle population down. Take away wolves and you end up with more cattle. More cattle eats more grass, too much grass. The grass is eaten faster than it can grow back. Cattle are being born more quickly than being eaten by wolves. The region would ultimately become uninhabitable and nothing could live there.
Constructive plate boundaries
1) Convection currents in the mantle move the plates
2) 2 plates of oceanic crust diverge/pull apart e.g. North American and Eurasian plates.
3)
The rising magma forces the ends of the plate to push up and buckle.
This creates tensional cracks on the underside of the plates.
4) Magma is squeezed into the gap between the two plates and is cooled by the ocean to form new, solidified rock/basalt.
5) Rising magma forces its way through the tensional cracks and forms sub-marine shield volcanoes on the ocean floor.
6)
With repeated eruptions over millions of years they can grow until
they break the surface of the ocean and become volcanic islands e.g.
Iceland.
