Student Exploration: Building Pangaea Anyone have the answer key to this?

Pangea is the name commonly used for the supercontinent, which formed about 300 million years ago and existed in the Paleozoic and Mesozoic before it split into smaller continents about 200 million years ago as a result of plate tectonics. When the continents first merged in Pangea, many mountains were formed, some of which still exist today, such as the Urals or the Antiatlas.

The disintegration of Pangea first gave rise to Gondwana and Laurasia. The further disintegration of Gondwana and Laurasia resulted in the creation of modern continents and islands with a continental crust.

Amath expression is a collection of one or more terms, which are separated by the signs ( + , - , x , / ).example :   8+b8+b  or  a−3a−3in algebra, an equation is a mathematical statement with two expressions where, each expression is separated by an equal (=) sign. variables can be present on both the sides of the equality (=) sign and we use letters to denote such variables.example 1:   x=4+2x=4+2  , [here, we can observe that the variable is present only on one side of the equation].example 2:   2x+3=x+42x+3=x+4  , [here, we can observe that the variables are present on both side of the equation].
