Density, because the core is made of metals like iron and nickel
Answer:
Mines are known to cause severe environmental problems. Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of sinkholes.

This is a short paraphrased summary of the article about ice cores in that website.
Answer: Researchers in labs may melt or crush bits of the ice core a little at a time, each deeper layer shows the time in the Earth's climate history. Tiny pieces of pollution, metals, radoiactive fallout, pebbles, sea salt, volcanic ash and even air bubbles all present important information that researchers can look for to track changes in the atmosphere's composition and temperature.
A geological fault is the type of fault which is caused by a crack in the <em>surface of the Earth's crust</em> and has to do with tectonic plates which <em>shift and change positions.</em>
As a result of this, we can see that these geological faults has to do with shifts of the tectonic plates which have the ability to cause earthquakes which can cause destruction of the earth.
With this in mind, there are different kinds of faults and they include:
- Normal Fault
- Reverse Fault
- Divergent Fault
- Strike-slip Fault, etc
Please note that your question is incomplete so I gave you a general overview to help you better understand the concept.

Dark Matter only: detected through its gravitational attraction, has mass, most common form of mass in the halo of the Milky Way Galaxy, likely to consist of subatomic particles
Dark Energy only: inferred to exist from the measured acceleration of the universe's expansion, the proposed source of a universal repulsive force
BOTH: the universe contains more of this than it contains matter made from atoms, we do not know what it is made of
NEITHER: blocks light from stars behind it, "dark" because it emits only infrared light
