Fill in the blank: Geologists have studied rocks from volcanic eruptions on the western coast of Africa and on the eastern coast of South America hundreds of millions of years ago. They determined that the volcanic rocks from both continents were identical in _______ and age.

• chemistry.

• color.

• texture.

• size.

The evidence from glacial features that supports the idea of continental drift is:

• the presence of glacial striations in tropical regions.

• the formation of fjords in coastal areas.

• the melting of glaciers in polar regions.

• the increase in glacial ice thickness.
