Question

The _____________ __________________ split the crust into a number of pieces and change
The physical features of the earth.
a. Convergent boundaries b. Convectional currents
c. Divergent boundaries d. Transform boundaries​

Answer 1

b. Convectional Current

$\rule{10cm}{0.05cm}$

Convectional Current :

• The Earth's crust is broken up into pieces called plates

• The crust moves because of movements deep inside the earth

• Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core

• The convection currents move the plates.

$\rule{10cm}{0.05cm}$

More info

• Divergent boundaries -- where new crust is generated as the plates pull away from each other.

• Convergent boundaries -- where crust is destroyed as one plate dives under another.

• Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.
