Which of these features of Earth's crust are caused by the shifting of tectonic plates?
A
mid-ocean ridges
B
desert sand dunes
С
arctic glaciers
D
continental shelves
To solve this we must be knowing each and every concept related to tectonic plates. Therefore, the correct option is option A among all the given options.
What is tectonic plates?The lithosphere, which includes the crust and topmost mantle, is divided into portions by tectonic plates. Numerous dangers, including volcanic eruptions, earthquakes, and tsunamis, are caused by the relative movement of tectonic plates.
Because of the makeup of the rocks inside the plates, tectonic plates can float on the mantle. This reduces their density relative to the mantle. Granite rock, which contains quartz, feldspar, as well as other relatively light materials mostly comprised of silicon and aluminum, makes up the continental crust. Mid-ocean ridges, earth's crust are caused by the shifting of tectonic plates.
Therefore, the correct option is option A.

Which pair of elements in the diagram is most likely to form a covalent bond?
Answer:
This question is incomplete
Explanation:
This question is incomplete. A covalent bond is a bond that involves the sharing of valence electrons (shared pair) by two atoms of the same/different elements/compounds. The electrons (valence) that are involved in covalent bonding are not the ones in pairs (lone pairs) on the outermost shell of the atom. For example, the single electron on a hydrogen atom is shared with another hydrogen to form hydrogen gas (H₂).
Another example is when the two individual/unpaired electrons on the outermost shell of an oxygen atom binds with two other unpaired electrons on the outermost shell of another oxygen atom.
Another example is when two different electrons from two hydrogen atom binds singly with the two unpaired electrons on the outermost shell of an oxygen atom to form water.
The diagram in the attachment provides illustration on the examples given.
Which statement describes a chemical property that many elements might share?
A. bonds easily with oxygen in the air
B. boils between 90°C and 100°C

a beaker contains 0.250 l of liquid. a student pours 0.00385 L of liquid out of the beaker. How much liquid remains in the beaker? choose the value reported with the correct number of significant figures
Answer:
The volume of the liquid remaining in the beaker is 0.24615 l
Explanation:
The initial volume of liquid in the beaker = 0.250 l
The volume of liquid the student pours out of the beaker = 0.00385 l
The volume of liquid remaining in the beaker, V, is given as follows;
V = The initial volume of liquid in the beaker - The volume of liquid the student pours out of the beaker
Therefore, we have;
V = 0.250 l - 0.00385 l = 0.24615 l
The volume of the liquid remaining in the beaker is 0.24615 l.

How do protons, neutrons, and electrons differ in terms of their electrical charges and
locations within the atom?
Answer:
Protons and Neutrons are large particles and are densely compacted into the nucleus of the atom. Protons are electrochemically positive in charge and the Neutrons are electrochemically neutral in charge. ... Electrons are electrochemically negatively charged particles that move random around the nucleus
Explanation:
Protons are positively charged, neutrons are neutral and they both are located in the nucleus whereas electrons are negatively charged and located outside the nucleus.
Explanation:
Atom is defined as the smallest unit of a matter.It consists of three subatomic particles: protons, neutrons, electrons.Protons and neutrons are located inside the nucleus. They are also known as nucleonsElectrons are located outside the nucleus.Protons carry a positive charge, electrons carry a negative charge, and neutrons carry no charge (neutral).So from this, we conclude that the protons are positively charged, neutrons are neutral and they both are located in the nucleus whereas electrons are negatively charged and located outside the nucleus

A student places 1.38g of unknown metal at 99.6C into 60.50g of water at 22.1C. The entire system reaches a uniform temperature at 31.6C. Calculate the specific heat of the metal
Explanation:
Heat energy lost by metal = Heat energy gained by water.
(0.00138kg) * c * (99.6-31.6) = (0.006050kg) * 4.148 * (31.6-22.1)
c = 2.541J/kg°C

A proton and a neutron are each close to a positive nucleus.
How does the charge on the nucleus affect the proton and the neutron, if at all?
A The neutron is attracted; the proton is repelled.
B The neutron is not affected; the proton is repelled.
C The proton is attracted; the neutron is repelled.
D The proton is not
Answer : The same charges will repel, since all protons are positively charged they will all repel so protons will repel. Neutrons don’t carry a charge so they can’t be repelled
So the answer is B: the neutron is not affected; the proton is repelled
Answer:
B
because the proton is positively charged and like charges repel, the neutron doesn't have a charge so nothing happens to it
Wait you wrote the answer in the question??
The way charge on the nucleus affect the proton and the neutron, if at all is the neutron is not affected; the proton is repelled.
What is electric charge?Electric charge refer to the physical property of a particle which direct or influence how it react to electric or magnetic force acting on it.
Therefore, The way charge on the nucleus affect the proton and the neutron, if at all is the neutron is not affected; the proton is repelled.

Imagine a friend is planning a rock-climbing trip. Write a note in the box explaining how gas exchange is affected at the top of a mountain, where air pressure is lower and there is less oxygen than at lower altitudes.
Answer:
Air is less dense on a mountaintop than at sea level.
Air pressure is lower at low altitudes.
As you climb a mountain, air pressure increases.
More force pushes on the air at the bottom of an air column.
As you descend a mountain, air molecules are closer together.
