Imagine you're exploring a museum dedicated to Earth's geography. As you wander through the exhibits, you come across a fascinating pie chart illustrating the distribution of Earth's surface between land and oceans.

Land and Ocean Distribution:

About 29% of the Earth's surface is covered by land, including continents and islands. Meanwhile, oceans dominate a significant portion, accounting for roughly 71% of the Earth's surface.

Which pie chart represents this distribution?

• 
• 
• 
•

• the water cycle will be slowed down

• the water cycle would stop without sunlight

• the water cycle will be unaffected by decreased sunlight
