Answer:
- Faunalturbation
- Cultural disturbance
- Graviturbation
Explanation:
Things that could account for these chronologically older artifacts that are found above the younger artifacts in a stratigraphic sequence include;
- Faunalturbation which is caused by animals involved in burrowing
- Cultural disturbance
- Graviturbation which is the mixing of soil by movement of artifacts down a slope under gravity.
Answer:
Self-cleaning systems
Explanation:
Oceans are natural self cleaning systems that can get rid of any material on their own.
At some parts of the ocean, new crust are being formed. In some other part, new crustal materials are added.
When organisms in the ocean die, they decay to produce some carbon compounds which goes back to the ocean and atmosphere. Their skeletal parts goes to the bottom of the ocean where it compacts with sediments to form new sedimentary rock sequences.
When wastes from land are brought into the ocean, they can be broken down on the long run.
The ocean is self cleaning and it is an effective system as such.
Answer:
True
Explanation:
This can be explained in accordance with the General Relativity theory of Einstein's which says that the time dilation depends directly on the intensity of gravitational field (for an observer outside the field).
So, as the intensity of the field increases so does the time dilation.
The black hole has highly intensified gravitational field and as such the time dilation near the boundary of the black hole also increases immensely and stops at the event horizon.
Thus the gravity of a black hole is sufficient enough to slow down a clock as one gets nearer to it.
