oceans, tropical plants, Europe
Step-by-step explanation:
Fossils on continents that are now separated by oceans support the theory of continental drift. Continents closer to the equator have warmer climates, yet fossils of tropical plants have been found on islands near the North Pole. This supports the idea that islands drifted from the equator. Coal fields in Europe match those found in North America, supporting the theory of continental drift.
The theory of continental drift was proposed by Alfred Wegener in the early part of 20th century. He suggested that the continents have once been joined together as a single landmass but have drifted to their current positions today.
- Fresh water fossils of organisms like Mesosaurus was found in parts of South America and Southern Africa. These organisms could not have swim between the oceans since they are localized to freshwater environments.
- Tropical plants have also been found in regions of the north pole.
- Coal fields in north America correlated with those in South America and this provided support to the theory of continental drift by Wegener.
- He also fitted the the world into a giant puzzle to support his claim.

We technically can't tell! Just because a pattern (increasing by two faces for every new pattern) is true at first doesn't mean it holds forever.
However, if we make the assumption that the number of smiley faces continues to increase by 2, we have 4+87*2=177 as the answer, since we start with four and continue through a total of 87 more patterns, each of which adds two more faces.
