Answer:
D. Continental Drift
Explanation:
Continental drift describes one of the earliest ways geologists thought continents moved over time. Today, the theory of continental drift has been replaced by the science of plate tectonics.
The theory of continental drift is most associated with the scientist Alfred Wegener. In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other. He called this movement continental drift.

Atoms will combine with each in order to become more chemically stable. Compounds are formed between two atoms that have
drag and drop answer here outer energy levels. The two types of compounds that can be formed between atoms are ionic and covalent.
Ionic compounds are formed between two drag and drop answer here charged atoms. Ionic compounds contain a drag and drop answer here ion and a
drag and drop answer here ion. Metals will lose electrons to form positive ions and nonmetals will gain electrons to form negative ions. These
oppositely charge ions are very attracted to each other and form very strong bonds as a result. Ionic compounds are characterized by crystalline
structure, drag and drop answer here melting and boiling points, and are drag and drop answer here at room temperature.
Two drag and drop answer here will combine to form covalent compounds. Covalent compounds are formed when two atoms drag and drop answer here
one or more pairs of electrons. The force of attraction between the nonmetals is relatively weak. Covalent compounds are characterized by
drag and drop answer here melting and boiling points and can be gases, liquids, or soft solids at room temperature.

why the Titanic sunk due to density.
Answer:
When the titanic hit the iceberg, water rushed into the ships hull and displaced the air. The average density of the water and the steel ship was greater than the density of the water. The result of this caused the titanic to sink to the bottom of the Atlantic.
calculate the moles and Molecules presents in ammonia present in 5.6dm3
of its volume STP?
Answer: 0.25 moles NH3
1.51x10^23 molecules NH3
Explanation:
5.6dm3 (cubic decimeters)
1 dm^3 = 1 liter
We have 5.6L of ammonia (NH3 gas) at STP. All gases at STP occupy 22.4 liters/mole. Use this information as a conversion factor:
(22.4 L NH3)/(mole NH3)
Therefore:
(5.6L NH3)/(22.4 L NH3)/(mole NH3) = 0.25 moles NH3
Use Avogadro's number to convert moles to particles/molecules
(0.25 moles NH3)*(6.02x10^23 molecules/mole) = 1.51x10^23 molecules NH3

What is the importance of water?
IMPORTANCE:
Water is very important. Whether it's from washing your dishes to hydrating, to simply just watering your flowers, water is important.
Washing Dishes
When you eat, after you eat, you wanna clean your dish. You're not gonna keep it dirty, you're going to have to wash it. Soap and water are often used when washing dishes. It's the best way to get it cleaned.
Hydration
Drinking water can have many benefits. It can make you more productive, you can even lose weight, no migraines, and it can boost your metabolism.
Watering Flowers
It's helpful to water plants because watering them on a basis/routine can help them gain nutrients. No watering the plant can result the plant drooping down and for it to become droopy and dry.

Suppose you wish to jump horizontally and in order for you to jump a distance of 4 feet horizontally, you must exert a force of 200 N. When you are standing on the ground, you have no trouble jumping 4 feet horizontally. If you are standing in a canoe, however, and you need to jump 4 feet to reach the pier, you will surely fall into the lake. Why is it that you cannot jump 4 feet out of a canoe when you can easily do this when on land?

Distinguish between efficiency and mechanical advantage.
Answer:
I think the answer is Mechanical advantage is a measure of how much your force is multipled efficiency is measure of how much of the work you do actually goes to moving the thing you are trying to move.
Adding more pulleys may increase the mechanical advantage but, it also increases the amount of extra stuff you are moving.

Describe the main energy level shape and of the 2p * orbital
Answer:
The letters, s, p, d, and f designate the shape of the orbital. (The shape is a consequence of the magnitude of the electron's angular momentum, resulting from its angular motion.) An s orbital is spherical with its centre at the nucleus.
why did bohr revise rutherford's model of the atom
Answer:
Bohr Atomic Model : In 1913 Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus. ... To remedy the stability problem, Bohr modified the Rutherford model by requiring that the electrons move in orbits of fixed size and energy.

Electron transfer occurs at an electrode of a galvanic cell
A Galvanic cell converts chemical energy into electrical energy.
There are two electrodes in a galvanic cell which are anode and cathode. The electrodes is where electron transfer occurs.
The anode is the electrode at which the oxidation (loss of electron) occurs whereas the cathode is the electrode at which the reduction (gain of electrons) occurs.
