Explanation: The Earth’s outermost layer, its crust, is rocky and rigid. There are two kinds of crust: continental crust, and ocean crust. Continental crust is thicker, and predominantly felsic in composition, meaning that it contains minerals that are richer in silica. The composition is important because it makes continental crust less dense than ocean crust.
Ocean crust is thinner, and predominantly mafic in composition. Mafic rocks contain minerals with less silica, but more iron and magnesium. Mafic rocks (and therefore ocean crust) are denser than the felsic rocks of continental crust.
The crust floats on the mantle. Continental crust floats higher in the mantle than ocean crust because of the lower density of continental crust. An important consequence of the difference in density is that if tectonic plates happen to bring ocean crust and continental crust into collision, the plate with ocean crust will be forced down into the mantle beneath the plate with continental crust.
Mantle
The mantle is almost entirely solid rock, but it is in constant motion, flowing very slowly. It is ultramafic in composition, meaning it has even more iron and magnesium than mafic rocks, and even less silica. Although the mantle has a similar chemical composition throughout, it has layers with different mineral compositions and different physical properties. It can have different mineral compositions and still be the same in chemical composition because the increasing pressure deeper in the mantle causes mineral structures to be reconfigured.
Rocks higher in the mantle are typically composed of peridotite, a rock dominated by the minerals olivine and pyroxene. The Tablelands rock in Figure 3.2 is a type of peridotite. Lower in the mantle, extreme pressures transform minerals and create rocks like eclogite (Figure 3.5), which contains garnets.

https://hub.jhu.edu/magazine/2015/summer/nursing-ethics-and-burnout/
Answer:
In every department of each health facility, nurses grapple with ethical challenges every day. Experts say that nurses face unique challenges because of long-term patient and family relationships. sometimes unsustainable decisions are nursing caregivers. "Nurses are often unable to choose patient care," says Rushton. Rushton. "Rushton says that the nation is at a crossroads in health," says a nursing and pediatrics professor. Some of these are serious situations. Johns Hopkins has initiatives and programs to stimulate ethics discussions, especially among nurses. Many hospitals have codes of conduct or guidelines which guarantee quality and safety, although fewer are ethical. Ethics can stay behind when nurses are busy, says Rushton. Initiatives are being developed in Kimmel Cancer Center to support nurses in tackling long-term cancer moral challenges. For students of the graduate school, the Johns Hopkins School of Nursing is specialized in ethics and theory. Students learn about their values and how to sympathize with those on the other side by engaging in debates and debates.
US Nurses Association that prepares to publish its report 50 health care leaders met for the First National Care Ethics Summit in Baltimore in August 2014. The resulting plan on the ethics of the 21st century lays down what can progressively be done to ensure that nurses are prepared. The nursing students of today are going to be nurses of tomorrow, says Rushton. He believes that the common voice of nursing workers can be mobilised in discussions with policymakers, hospital administrators, medical organizations and insurance companies in order to create a culture that values and promotes the practice of ethics. The ANA celebrated its release with 2015 as "the Year of Ethics"
Explanation:
Heres #1, on the 2nd question look for key ideas that lead to 4 ethical discussions. Good luck!
If a cubical cell with 2-cm sides doubles the dimensions of its sides, what relative change occurs to the ratio of its surface area to volume ratio?
Answer:
When the length of the side of the cube is doubled, the area increases by a factor of four while the volume increases by a factor of eight.
Explanation:
Surface area of a cube is given by the formula below:
Surface area of a cube = 6a²
Volume of a cube is also given by the formula below:
Volume of a cube = a³
Where a is the length of a side of the cube.
For the first cube, a = 2 cm
Surface area of the first cube = 6 * (2 cm)² = 24 cm²
Volume of the first cube = (2 cm)³ = 8 cm³
When the side length of the cube doubles, a = 4 cm
Surface area of the second cube = 6 * (4 cm)² = 96 cm²
Volume of the first cube = (4 cm)³ = 64 cm³
The ratio of the area and volume of the new cube is given below:
Area = 96 cm² / 24 cm² = 4
Volume = 64 cm³ / 8 cm³ = 8
Therefore, when the length of the side of the cube is doubled, the area increases by a factor of four while the volume increases by a factor of eight.

What are people in a coastal location in Florida most likely to do if there are moderate winds and waves along the shore?
Build barriers on the coastline to prevent flooding
Engage in water sports like surfing
Enjoy recreational activities off the beach
Shift to inland locations temporarily
Answer:
b
Explanation:
cause a smart dude in the first comment section said so
Engage in water sports like surfing is the coastal location in Florida most likely to do if there are moderate winds and waves along the shore.
What is Coastline?There are approximately 312,000 kilometers of coasts on the continents of the world (193,000 miles). They have changed positions during geologic time as a result of significant alterations in the relative levels of land and sea.
All coastal regions were impacted by sea level dips brought on by the loss of water from the oceans during glacial advances, according to studies of glaciations during the Pleistocene Era.
The sea level during the last Pleistocene glacial epoch is considered to have been nearly 122 m lower than it is now, exposing a significant chunk of what is now the continental shelf.
Therefore, Engage in water sports like surfing is the coastal location in Florida most likely to do if there are moderate winds and waves along the shore.

Which type of mixture is it, if the solid settles out of the mixture over time?
O suspension
o homogenous
o colloid
solution
Answer:
Suspension
Explanation:
A suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing. The particles in a suspension are far larger than those of a solution and thus gravity is able to pull them down out of the dispersion medium (water).
If the solids settle out of the mixture over time, such a type of mixture is called suspension.
A suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing.
What are the different types of mixtures?
there are mainly two types of mixtures that are:
homogeneous mixture
homogeneous mixture
A homogeneous mixture is a mixture throughout the solution in which the composition is uniform throughout the mixture.
A homogeneous mixture is a mixture in which the composition is not uniform throughout the mixture.
Hence, a suspension is a heterogeneous mixture in which some of the particles settle out over time.
