Answer:

Attached is the picture for "record A"

Explanation:

Sequences I - A were deposited layer by layer into a sedimentary basin (a region or place where subsidence of Earth's crust has allowed sediment to accumulate on top of metamorphic and igneous rock). They were subjected to Lithification and became compacted, forming sedimentary rocks. With time, the layers became tilted due to natural forces. Geologic tilting can occur as a result of faults (vertical or horizontal), angular unconformity and disturbances to the earth's magnetic field or even erosion, so possibly strata of sedimentary rock was deposited on layers that were tilted due to erosion, and the new layers were compressed on top of previously tilted layers, aggravating the tilting further. After the tilting, there was a period of non-deposition, and the exposed surface of the bed became eroded due to denudation. After this, layers H - C were deposited and compacted under pressure, by lithification. Some rock layers were exposed as the rock sequence was uplifted, and erosion washed away parts of layers C and E, and layer C has been eroded to the level of layer E. When layer C was exposed and eroded, the load was relieved and part of bed E re-adjusted to the level of C.

The search for black holes has so far turned up some fairly convincing stellar-sized candidates in binary star systems. What obs

ozzi

Answer:

Th similarities between the black hole and the neutron star is that they are formed from dead (dying) starts. But they come from different parent stars, if the parent star is 1.4 times the mass of the sun, a neutron star will be formed, but if the parent star is twice the mass of the sun a black hole is formed.

Explanation:

A black hole is defined as an area of space whereby the matter is so compacted that nothing can escape from it. This area is called <em>event horizon. </em>Black holes are formed when an enormous star dies in z supernova. They weigh at least twice the sun's mass, and their mass is directly proportional to their radii.

Neutron stars are created during supernova and maintained by a neutron called <em>degeneracy pressure.</em> Neutron star has a small radius, typically 30 km, with a very high density made up of compacted neutrons.

Position of land masses of early Pennsylvania can be determined through fossil records because we know that most plants presentl

agasfer [191]

Answer:

a. plants are preserved as fossils

Explanation:

Through the passing of time, the dead bodies like plants or animals rest in soil, and the cover by different particles, with the time they can be compressed and form a soil layer. If the environment condition changes they get caught in one soil layer. If this process is repeated constantly, so a new soil layer will be formed. So passing the time, different soil layers will have different animals or plants. With the help of isotopes, the scientist can determine the years of each layer.

11- Explain how carbon moves through the Earth system (including the geosphere) and how it may benefit (e.g., improve soils for

LiRa [457]

Answer:

The Carbon Cycle. The main benefits are Plant growth and enrichment of agricultural soils. The main Harms are air pollution

Explanation:

Carbon movement on Earth is best-explained trough the Carbon Cycle, in this cycle carbon is stored, moves or is exchanged between the biosphere, the Atmosphere, Oceans, and the Geosphere.

Atmosphere storages big quantities of carbon. this carbon then cycles to the Biosphere where it is used mainly by the plants on the photosynthesis and respiration processes.

Oceans also plays an important role in the cycle by photosynthesis of seagrass and algae, the air and the sea also exchanges carbon present in the surface ocean. But also large amounts of carbon are stored in the deep ocean (about 37,000 gigatons of carbon per year).

In the Geosphere the Carbon Cycle is slower because it involves processes like rain that forms carbonic acid when in contact with the rocks, this acid promotes chemical weathering on rocks releasing elements like calcium and magnesium that are carried over to the oceans, in the oceans, Calcium carbonate is formed trough the calcification of organisms that are layered throughout the years, this calcium carbonate is then cemented and turned to rock. Organic carbon is also present in the Geosphere as a result of dead plant matter.

This carbon stored in the lithosphere is released back to the atmosphere through volcanism, and the cycle repeats.

societies greatly benefit from carbon because of the plant respiration and growth process, also carbon is an element present on rich soils for agriculture.

The main harm to society is air pollution. Humans emissions have an important impact on carbon cycle by adding more C02 to the atmosphere in the form of Black carbon (produced by combustion process) and because of deforestation, the Carbon exchange with plants is reduced, increasing pollutants to the air.

Describe the diffrence between a closed circuit and an open circuit

kari74 [83]

Answer:

An open circuit is one where the continuity has been broken by an interruption in the path for current to flow. A closed circuit is one that is complete, with good continuity throughout.

Explanation:

For instance, a simple light switch opens and closes the circuit that connects a light to a power source. When you build a circuit, it's a good idea to disconnect the battery or other power source when the circuit is not in use.
