Question

1 at the end of the paleozoic time, there was one continent and one ocean. the continent was named pangaea and the one ocean was named panthalassa. this one landmass existed for tens of millions of years. why would a huge land mass like this break apart?

a land mass of that size would not allow heat to escape from underneath very well. as the heat built up, continental rifting would begin.

active volcanoes would melt the earths crust and weaken areas that could then break away from the main land mass.

large explosions would happen due to the radioactive isotopes in the rocks and under the earths crust, pushing parts of the land away from the central land mass.

as meteors hit the earth, some would impact pangaea and would be big enough impacts that chunks of the land would break off

1. which process created the great rift valley in africa?

Explanation:

For question 1, the breakup of Pangaea is primarily driven by tectonic forces from heat buildup in the mantle. A large landmass restricts heat escape, leading to mantle convection and continental rifting. For question 2, the provided text cuts off, so no answer can be given for it.

Answer:

1. A. A land mass of that size would not allow heat to escape from underneath very well. As the heat built up, continental rifting would begin.
2. (Incomplete question, no answer available)
