Which Of The Following Is In Agreement With The General Pattern In The Solar System

Analyses of rock formations and fossil records are used to determine relative age. In an undisturbed rock column are the youngest rocks at the top and the oldest at the bottom. The rock layers were sometimes rearranged by tectonic forces; Rearrangements may be seen or derived, para. B example from inverted sequences of fossil types. Cores taken from drilling show that rocks from continents (some as old as 4 billion years or more) are much older than rocks from the seabed (less than 200 million years old), where tectonic processes are constantly creating new rocks and destroying old ones. The rock record shows that events on Earth can be catastrophic that occur over hours to years, or gradually, over thousands to millions of years. The record of fossils and other rocks also shows past periods of mass extinction and extensive volcanic activity. Although active geological processes, such as plate tectonics (link with ESS2. B) and erosion, have destroyed or altered most of the very first rock records on Earth, some other objects in the solar system, such as asteroids and meteorites, have hardly changed over billions of years. Studying these objects can help scientists deduce the age and history of the solar system, including the formation of planet Earth. Studying other planets and their moons, many of which have Earth-like characteristics, such as volcanism and meteorite impacts, also helps shed light on aspects of Earth`s history and changes. Until the end of the 8th year. At the end of Grade 12.

Earth systems, which are dynamic and interact, cause feedback effects that can amplify or decrease the original changes. .
