Which piece of evidence did Alfred Wegener's original theory of continental drift have access to?
A.) reversing paleomagnetism in rocks on the ocean floor
B.) seafloor spreading at mid-ocean ridges
C.) a seafloor that was geologically active with earthquakes, volcanoes, and mountain chains
D.) mountains in North America appearing to match up with mountains in Northern Europe
Answers
The piece of evidence that Alfred Wegener's original theory of continental drift has access to is the mountains in North America appearing to match up with mountains in Northern Europe. Thus, the correct option for this question is D.
What is Continental drift?Continental drift may be defined as a type of hypothesis that represents a gradual movement of the Earth's continents over geologic time relative to each other. This movement of the Earth's continents results from the motion of tectonic plates.
According to Alfred Wegener's original theory of continental drift, the continents of the Earth have been adjoined together and have migrated away from each other at different times in the history of the Earth.
This reflects that mountains in the continent of North America appear to match up with the mountains in the continent of Northern Europe.
Therefore, the correct option for this question is D.

The matter can be observed all over the Universe present in a few forms in the system. Scientists discover more states of matter.
What is system ?The part of the universe in a thermodynamic consideration is called a system and the remaining portion of the universe is called surroundings.
Universe can be a combination of system + surroundings
A system is called as open system where exchange of both matter and energy with their surroundings, If water is kept in an open vessel it is allowed to exchange of matter and energy.
Closed system is defined as the exchange of energy with the surroundings, like if some water is placed in a closed metallic vessel, so no exchange of matter occur between the system and the surrounding can take place.
Isolated system is defined as the system where neither matter exchanged nor energy with the surroundings; Homogeneous and Heterogeneous systems refers to any system which consist of a single phase is called Homogeneous and if any system has more than one phase is called Heterogeneous.

Answers
Answer:
The light colored pepper moths were able to camouflage in the Birchwood trees unlike the darker ones. But when the industrial revolution came the amount of smoke from the factories made the Birchwood trees become darker in color do now the darker pepper moths were the ones who could camouflage while the white ones were easily eaten and killed. Since the darker colored moths were able to survive they had offspring who were also darker colored. Over time since mainly darker moths were produced it was common for pepper moths to be darker.
