Which scientific discovery supports the claim that Earth has changed over time?
Vanyuwa [196]

Answer:

Rocks found on different mountains are different ages.

Explanation:

Radiometric dating of rocks and fossil records gives scientists an idea of the timelines of certain organisms. Fossils of long dead species found in different strata of rocks can be used to speculate the age and changes these organisms have experienced overtime.

Fossils found in the uppermost strata are indicative of organisms that died not quite long whereas fossils found in lower layers are indicate of organisms that died a long while ago. These studies also provide insight into the changes that the earth has experienced overtime.

What process is a good example of a positive feedback that then reaches an equilibrium in an Earth system?
ipn [44]

Answer:

The relationship between the warming of the earth’s northern latitude and ice is a practical example of a positive feedback on the earth system.

Explanation:

A positive feedback is a process that brings about an increase in the process of interaction in the earth activities The warming of the northern latitude which is responsible for generating more heat through sunlight with time, usually results in an increase in the melting of ice bodies in the ocean by movement. This activity is regarded as positive because it is associated with an increase in the process. This process is directly proportional to the exchange activities that takes place and often leads to an equilibrium in the earth system.
