Answer:
Through the study of meteorites, their chemical composition of silicates—material made of silicon and oxygen. Others contain metal—nickel and iron. Knowing what the meteorite was composed of lets you know where it came from. Chondrites are composed of hardened lava - this is occurred at the beginning of the solar system (4.5 mya). Carbonaceous chondrites contain carbon and water which formed away from the sun.

Answer:
By establishing linking features of fossils in different age brackets through radioactive dating
Explanation:
Radioactive dating estimates the age of fossils and rock. Fossils are remains of living organisms that are primarily found in the sedimentary rocks. Carbon dating is used to determine the age of the fossils that are not older than 50 thousand years.
For fossils older than that uranium dating is used. Based on the age estimation of fossils, fossils belonging to the same age bracket are grouped from the oldest time to the most recent time thereby marking the common characteristics of different fossils at each age brackets. In this way radioactive dating helps the scientist in establishing evolutionary links.
Answer:
Inertial confinement fusion
Explanation:
A. Carbon dioxide levels are increasing in the air, and the ocean is absorbing carbon dioxide; atmospheric levels are increasing so much that the increase is still apparent even with increasing absorption of carbon dioxide by the ocean. Research conducted by the University of Miami (UM) has found that the waters of the North Atlantic absorbed 50 percent more carbon dioxide of human origin in the last ten years than in the past decade.
The results of the study show the impact that the burning of fossil fuels has had on the world's oceans in the last ten years
