The answer would be C. Germany has recently changed the legal retirement age to 67.
The main mechanism through which the layering happened is gravity: it pulled the heavier, denser material to the center, leaving the less dense material on the surface.
The material that was on the outside cooled quicker, but this was the result, not the cause.
The answer is
<span>2) Gravity caused more-dense material to move toward the center of each planet.</span>
Answer:
The diameter of the Milky Way is 3,503,974,249,104 km times larger than the diameter of Saturn's rings.
Explanation:
1 light year is the distance light can travel in one year. One light year is equal to exactly to 9,460,730,472,580.8 km.
Therefore the diameter of the milky way in distance is 9,460,730,472,580.8 x 
km while the diameter of Saturn rings are about 270,000km.
Comparing both diameters
= 
= 3,503,974,249,104 km
Answer:
46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).
Explanation:

Answer:
volcanoes and earthquakes is the top tectonic plate affects that can cause extinction
Explanation:
Volcanoes: because of a volcanoes lava intense heat it could kill species. Lava is the hottest natural substance there is on earth. Also the fumes and gases that come from volcanoes are deadly and can kill species that inhale it even if the volcano is miles away.
Earthquakes: the highest stage of a earthquake can be devastating cracking open grounds and destroying everything in its path which also means that it can destroy certain species homes (trees, underground, mountains) which can kill them. Also they can cause land slides which can wipe out a species instantly if strong enough. Even the after affect can causes species to go extinct because if they can't find shelter or food then they could eventually die of starvation or dehydration.
