While researching a topic, a student has taken the following notes:

• A supercontinent is a single landmass made up of most or all of Earth’s continents.
• Over time, continents merge together to form supercontinents, which then break apart.
• This process is believed to take hundreds of millions of years and is known as the supercontinent cycle.
• Rodinia and Euramerica were supercontinents.
• Rodinia formed about 1.1 billion years ago.
• Euramerica formed about 300 million years ago.

The student wants to correct a misunderstanding that Euramerica formed before Rodinia. Which choice most effectively uses relevant information from the notes to accomplish this goal?

A

Rodinia and Euramerica were both supercontinents, single landmasses made up of most or all of the Earth’s continents.

B

Rodinia formed about 1.1 billion years ago, long before Euramerica’s formation about 300 million years ago.

C

Forming and breaking apart over hundreds of millions of years, supercontinents are made up of most or all of Earth’s continents.

D

Euramerica and Rodinia formed at different times in Earth’s history.
