which explanations provide support for continental drift theory? check all that apply.

dinosaurs lived on many continents.

coal fields match up across continents.

tropical plant fossils were found in arctic areas.

similar rock types are found across continents.

evidence of glaciers can be found in south africa.

Answer: All of the statements apply.

Explanations:

1.  Dinosaurs lived on many continents.

One proof for the continental drift theory is the presence of dinosaur fossils belonging to the same species on different continents. Without the existence of Pangaea, the current distances between the continents would have been to great to be crossed.

2. Coal fields match up across continents.

Wegener noticed that the coal fields from Europe and North America match up. Coal is formed from ancient coral reefs and swamps. However, the fields' locations are in areas that are too cold to have supported these types of environments. Thus, the continents have moved to their current colder positions in time through continental drift.

3.  Tropical plant fossils were found in Arctic areas.

In order to have supported tropical plants, the landmasses currently in Arctic areas must have been in warmer regions sometime in the past.

4. Similar rock types are found across continents.

Wegener found identical rocks in both type and similar age could be found on both sides of the Atlantic. One example are the rock structures similar to the Appalachian Mountains also present in Europe.

5.  Evidence of glaciers can be found in South Africa.

Glacial scratches - striations have been found on the bedrock in warm areas such as South Africa. These could have been made only through moving blocks of rock embedded in the glacier.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

the correct answer is 2 and 4
