To determine which of these biomes covers the largest area of Earth, you can utilize information and data readily available. One reliable source to consult is the World Wide Fund for Nature (WWF), which is a well-known organization that focuses on the conservation of nature and the environment.

To find the answer to your question, you can follow these steps:

1. Open a web browser and search for "World Wide Fund for Nature" or simply "WWF."
2. On the WWF website, look for a navigation menu or search bar to explore their resources and information.
3. Type "biomes" or "terrestrial biomes" into the search bar to find the specific section that discusses different biomes.
4. Within the "biomes" section, you should find descriptions of various biomes, including their sizes and locations.
5. Look for the information related to each biome mentioned in your question: tundra, marine, grassland, and forest.
6. Compare the sizes mentioned in the descriptions for each biome to determine which one covers the largest area of Earth.

Based on the available information, the answer to your question is most likely the marine biome. The Earth's oceans and seas make up around 71% of the planet's surface, which significantly surpasses the areas covered by the other mentioned biomes.
