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.

Answer:
Hi,
Geologists obtain indirect evidence about the earth’s interior by studying seismic waves produced.
Explanation:
Geologists are able to study the layers of the interior of the earth by observing the seismic waves patterns. The recorded data for the waves can show how the waves traveled through the earth and the path followed which will reveal the structure of the interior of the earth. The speed and magnitude of the wave can further reveal the characteristics of the earth’s interior.
Best wishes!

Answer:
The Hadean eon represents the time interval between 4.6 billion to 4 billion years back. It is marked by the initial formation of the earth , right from the time of gathering and accumulation of interstellar dust particles and gases, and there was frequent collision between the planetesimals of relatively larger in size. The core and the crust formed and started to become stable and also gradually led to the formation and expansion of the ocean and the earth's atmosphere.
This is how the earth gradually started to form and develop and took the shape during the time interval between 4.6 billion to 4.2 billion years old, and where the oldest rocks found on earth is dated from about 4.2 billion years in the past.
