b. solar radiation
c. heat and convection currents in the mantle
d. wind erosion

which scientist proposed the theory of continental drift and named pangaea? *
a. charles darwin
b. alfred wegener
c. isaac newton
d. galileo galilei

what is the earths outermost solid layer? *
a. inner core
b. crust
c. mantle
d. outer core

Explanation:

1. The movement of Earth's lithospheric plates is caused by heat and convection currents in the mantle. These currents transfer heat from the Earth's interior, driving the slow - motion of the plates.
2. Alfred Wegener proposed the theory of continental drift and named the super - continent Pangaea. His work was based on various geological and paleontological evidence.
3. The Earth's outermost solid layer is the crust. It is the thin, solid shell of the Earth where we live and where most geological activity occurs.

Answer:

1. C. Heat and convection currents in the mantle
2. B. Alfred Wegener
3. B. Crust
