It was one of the earliest times the concept of crustal motion had been presented to the scientific world, and it lay the foundation for the creation of current plate tectonics, even if Wegener's "continental drift" hypothesis was eventually refuted.
In order to comprehend mountain-building processes, volcanic eruptions, earthquakes, the evolution of the Earth's surface, and rebuild the continents and oceans that once covered it, plate tectonics, a theory about the dynamics of the lithosphere, revolutionized Earth sciences.
In the 1960s, the theory of tectonics was developed. The lithosphere, which really is typically 100 km thick and sits on top of the asthenosphere, a plastic layer, is said to be Earth's outermost, unyielding layer.
The lithosphere is divided into several small plates, six to eight medium-sized local plates, and seven extremely massive continental and oceanic plates.

The acceleration of gravity is 9.81 m/s?.
If the upward acceleration of the bucket is
2.8 m/s², find the force exerted by the rope
on the bucket of water.
1. 69.658
2. 52.84
3. 85.318
4. 70.86
5. 84.429
Explanation:
Draw a free body diagram of the bucket. There are two forces:
Tension force T pulling up.
Weight force mg pulling down.
Sum of forces in the y direction:
∑F = ma
T − mg = ma
T = mg + ma
T = m (g + a)
Given m = 4.0 kg, g = 9.81 m/s², and a = 2.8 m/s²:
T = (4.0 kg) (9.81 m/s² + 2.8 m/s²)
T = 50.44 N
An element from group 2 will form ionic bonds with a nonmetal group 13-17, therefore the correct answer is option C.
When electrons are moved from the atoms of one element to the atoms of another, creating positive and negative ions, ionic bonds are created. Ionic bonds are only between metals and non-metals occur. There can not be the formation of the ionic bond between two metals.
These ionic bonds are also known as electrovalent bonds as they are formed because of the transfer of the electrons.
There must be one electropositive element that can release electrons which is metal as metals have extra electrons in their valence shell.
There must be one electronegative element involved during the formation of the ionic bond, which is a nonmetal as nonmetals have few electrons left to complete their outermost shell.
As given in the problem element of group 2 are metals and will form ionic bonds with the nonmetal elements of the group 13-17.
Thus, the correct answer is option C.

To convert from Celcius to Kelvin just add 273
-30C + 273 = 243 Kelvin
10C + 273 = 283 Kelvin
50C + 273 = 323 Kelvin
To convert from Celcius to Fahrenheit is C * 1.8 +32
-30C * 1.8 + 32 = -22F
10C * 1.8 + 32 = 50F
50C * 1.8 + 32 = 122F
Hope that helps!
