Answer:
<u>Past is key to future and landmarks are ket sign and indicators.</u>
Explanation:
- Many landmarks have been built in the history of the earth such as the Mount Rushmore, Eiffel Tower, Statue of Liberty and many more the Burj Khalifa, and Berlin wall.
- Their basic construct was to put represent civilization like it's in Brazil statue of christ redeemer is know for peace and landmark of Stonehenge on easter island. It depicts a civilization's history and past experiences.
- landmarks as a way of identifying the place with some characteristics that the place has to offer to the future generation so as they can understand and learn from them. They are marked on the history of the earth's surface.
- Some are known for sacrifice, some for rituals, some for freedom and others to represent the amount of power or dominance.
I belive it it O because <span>An O horizon has at least 20% </span>organic matter<span> by mass. Two main scenarios result in the formation of an O horizon: saturated, </span>anaerobic<span> conditions (wetlands) or high production of leaf litter in forested areas. Anaerobic conditions slow the </span>decomposition<span> process and allow organic material to accumulate. An O horizon can have various stages of decomposed organic matter: highly decomposed, sapric; moderately decomposed, hemic; and minimally decomposed, fibric. In a fibric O layer, plant matter is recognizable (e.g., it is possible to identify a leaf). Sapric material is broken down into much finer matter and is unrecognizable as a plant part. Hemic is in between sapric and fibric, with some barely recognizable plant material present. It is possible to have multiple O horizons stacked upon one another exhibiting different decomposition stages. Because of their organic content, these horizons are typically black or dark brown in color. The dominant processes of the O horizon are </span>additions<span> of organic matter, and </span><span>transformations </span><span>from fibric to sapric

Answer:
A
Explanation:
Formation of black holes occur during the death of massive stars (at least 25 times larger than Earth’s sun). When the fuel of the massive star is exhausted, the star’s nuclear forces are unable to counter the gravitational collapse due to its own weight. The star dies in a supernovae and the remnant is a black hole.
Answer:
B. the very quick rise in prices of goods that decreases the value of a country's currency.
<u>Answer:</u>
<em>A. Mantle convection
</em>
<em></em>
<u>Explanation:</u>
Ridges are formed over the divergent plate boundaries, it can be pushed by the mantle plume volcanism originated by the core mantle boundary at the Asthenosphere region over the divergent plate boundary. Seafloor spreading is the one of the evidences of plate tectonics theory. Subduction of the plate is the result of ridge push and slab pull, oceanic plate is less dense so its under beneath the high denser continental plate.
