To complete the sentence "Just like Earth, Mars has ______, which are large, flat areas with no trees," the correct word is d. plains.

Explanation

1. Channels refer to long, narrow depressions, often formed by the flow of fluids, and are not necessarily flat areas.

2. Valleys are low areas between hills or mountains, typically characterized by a "V" shape, and while they can be flat at the bottom, they do not quantify as large flat areas like plains do.

3. Crater describes a bowl-shaped depression formed by volcanic activity or impact from space objects, which does not match the description of large, flat areas.

4. Plains, on the other hand, are extensive areas of flat land that typically have few trees, making them the perfect term to fill in the blank.

In summary, plains are a common geographic feature found both on Earth and Mars, characterized by their broad, flat expanses without significant vegetation, thus the choice is clear.

Final Answer

d. plains
