The identical glacial weathering and erosion patterns discovered on separate continents are a proof of the plate tectonics theory.

Explanation:

In recent times, with the more and more research that has been conducted, it has been noticed that there are physical features that are identical, but on separate continents. These physical features are of glacial origin, or rather caused by glacial weathering and erosion. Considering that the patterns are identical, it is clear that they have occurred at the same time, and that they have occurred on the same place.

This has been seen as big proof of the plate tectonics theory. This kind of features have been found int he southern part of Africa and northern part of Antarctica, which just supports the theory that they were once part of a same landmass. That landmass is called Gondwanaland, and it also was consisted of South America, Australia, and India.

Which feature do amber fossils have that mold fossils do not?

Answer:

They preserve the entire fossil remain rather than there traces.

Explanation:

Amber is a fossilized resin from an ancient forest. It used as a healing agent in folklore. It is a product of high pressure and temperature.

They occur in a wide range of color and many geological records are found in amber hidden fossils. Its main property is to preserve the complete chemical and physical properties of the fossil.

Oldest known amber was of an arthropod, often found in association with insects. The amber fossils are believed to have been derived from older Eocene deposits. Later formations of glacial drift.

While a mold of fossil is formed by an animal, plane or other organisms which upon dying to get covered sediments and later its bones are decay due to chemical processes. Mold fossils tell traces of extinct organisms like trail track etc.
