Answer:
<u>Wegener gave many evidence to the theory of plate tectonics another piece of evidence was the finding of fossils of reptiles in oceans and glossiperious fauna and the similarity of glaciers in all continents</u>
Explanation:
- Alfred Wegener is supposed to believe that the supercontinent named Pangaea consisting of northern continents and the southern continent i.e Gondwanaland consisting of southern continents were once the same.
- Thus he gave evidence in the shape of puzzle-like fit of the continents as similarity of rocks found in the continent's of Africa and South America, as they were one earlier.
- Further, he gave the supporting pieces of evidence as the glacier landmasses distributed were the same part earlier drifted away from the larger continent of Greenland.
- The supporting evidence the put forth was the polar wandering forces that he called the flight from poles and drift under the impact of moons gravity and another evidence was the thin sheets or plate moved away due to the wind.

Answer:</h2><h3>
a. tropical -- heat and rain.</h3><h3>
b. dry --- heat and dryness.</h3><h3>
c. moderate -- always near an ocean.</h3><h3>
d. continental --- ice year round.</h3>
<h2>
Explanation:</h2><h3><em>A tropical climate is known for the heat and the rainfall and the dry climate is known for the heat and the humidity and the dryness is known for the lands of the increased salinity and the moderate effects of the climate is found near the oceans and the seas and thus the continents known to occur at the icy with an year around as in the case of the antarctic and the arctic circles. They have an extremity climate.</em></h3>

Answer:
Movements along faults can make it harder for geologists to determine the relative ages of rock layers.
Explanation:
The absolute age of a sample is its age in years. This method of determining absolute age is called radiometric dating, and it involves the decay, or breakdown, of radioactive elements. Using radiometric dating, scientists can determine the actual age of a rock.
Answer: is constant
Explanation:
In order to analyze the velocity of the stars within a galaxy, the <u>galaxy rotation curves</u> (developed by the American astronomer Vera Rubin) are used. These graphs are elaborated as a scatter diagram in which the orbital velocity of the stars present in a galaxy is represented on the Y axis and the distance of these stars to the center of the galaxy on the X axis.
Thanks to this diagram, it has been possible to observe a characteristic behavior in the rotation speed of the stars (and gas) present in the galaxies, which differs from the rules of the orbital movement of the planetary systems postulated by Newton and Kepler.
This means that in these galaxy rotation curves it has been observed that the rotation speed of stars and gas is "constant", regardless of the distance to the center of the galaxy. This discrepancy and these results were then used to demonstrate the existence of dark matter in the universe.
