An earthquake's epicenter is the earthquake's focus
Answer:
Disturbances can leave legacies or traces in the landscape, vegetation or soils of variable duration. They can alter the ecological succession.
Explanation:
Ecological succession is the evolution that occurs naturally, producing a dynamic ecosystem.
A disturbance is any discrete and external event that alters an ecosystem, community or population, which changes the availability of resources or physical environment.
Agents of natural disturbances:
• Winds (storms, hurricanes, tornadoes)
• Tree falls
• Moving water (floods)
• Landslides
• Frost
• Droughts
• Fires
• Animals (grazing, pests)
Human disturbances:
• Agriculture and grazing
• Mining
• Pollution
• Irradiation
• Fires
The disturbances, depending on their characteristics, can leave legacies or traces in the landscape, vegetation or soils of variable duration. They can alter the ecological succession.

In Earth's climate system, positive feedback's tend to amplify changes in the system, and negative feedback's tend to encourage the system against change. Having a positive feedback gives the newest updates and brings the problems on the table, thus changes are always a must when there's proof that suggest there's big problem, but when the feedback is negative, lacking, then there's not pressure for changes, so anyone who has interest in not changing will push for that, thus encouragement of taking no changes. <span />
I agree with the answer above - boreal forests are the kind of forests that remain green all year, because evergreen trees can be found there. Opposite of this, temperate forests do not stay green all year, because they have deciduous trees, which means their leaves fall off.
