<u>Explanation for part 4 :</u>

Compound : It is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.

For example : The carbon tetrachloride (CCl_4) is made from atoms of different elements (carbon and chlorine) combined together in a fixed ratio by mass.

The carbon dioxide (CO_2) is made from atoms of different elements (carbon and oxygen) combined together in a fixed ratio by mass.

Element : It is a pure substance which is composed of atoms of similar elements.

For example : The molecule of hydrogen element (H_2) is made from atoms of similar element (hydrogen).

The molecule of nitrogen element (N_2) is made from atoms of similar element (nitrogen).

<u>Explanation for part 5 :</u>

Atom : It is a smallest unit of matter which can not be further divide.

When the atoms have equal number of protons (which is positively charged) and electrons (which is negatively charged) then the atoms are electrically neutral.

When an atom gains or lose one or more electrons then it becomes an ion. The ion can be anion by gaining an electron and can be cation by losing an electron.

Hence, the atoms are electrically neutral when an atom have equal number of protons and electrons.

Ok let's do this, Big brain moment. Hope you ready.

#4. Sulfuric acid (H2SO4) - Molecular Compound

normally are atoms of other atoms from different elements mixed together to make a new compound, in this case we got ( 2 Hydrogen, 1 sulfur, 4 Oxygen)

34. (part 2) Molecule of a element would normally just be the one atom of the one specific element for example Hydrogen again, it has one electron orbiting its center and thats it.

   

#5. A atom is electrically neutral when it is by its self and has the same number of protons as it does electrons so there is no extra charge existing in the atom

A wave of infrared light has a speed of 6 m/s and a wavelength of 12 m. What is the frequency of this wave?
andreev551 [17]

Answer: The frequency of the wave is 0.5 hertz.

Explanation:

\nu =\frac{c}{\lambda }

\nu = Frequency of the wave

c = speed of the light in m/s

\lambda = Wavelength of the wave.

Here in question we are given with speed of the infrared light. So, we will replace the value of speed of light(c) from the given value of the speed of the infrared light.

Speed of infrared light = 6 m/s

\nu =\frac{\text{speed of infrared light}}{\lambda }=\frac{6 m/s}{12 m}=0.5 hertz

The frequency of the wave is 0.5 hertz.

Answer:

1. False - compression

2. True

3. False - transform faults

4. False - horizontally

5. True

6. False- perpendicular

7. False - away from

8. False - increase

9. True

10. True

Explanation:

1. Mountains, oceanic trenches, and rift valleys are created by tension and compression stress. They are formed by divergent and convergent boundaries. Compression stress occurs when plates are pushing against each other, while tension stress occurs when the plates are pulling away from each other.

**Shear stress happens when the plates grind against each other. Often found in transform boundaries.

2. Transform faults happen when two plates glide or slide against each other. These areas are called transform boundaries. Transform faults occur in the ocean. When these boundaries are formed on land, they are called strike-slip faults.

3. Shear stress that occur in transform boundaries produce transform faults. These faults are usually identified by long faults and ridges. Sometimes small ponds form in the cracks due to deposition.

*** Rift valleys are produced by divergent boundaries or tension stress, when the plates are pulled apart.

4. Transform boundaries are formed when two plates slides against each other. Transform faults are formed in these boundaries and the movement of the plates are horizontal.

*** They do not move vertically.

5-6. Mid-oceanic ridges are segmented or divided by transform faults. The transform faults in the mid-oceanic ridges are perpendicular to the oceanic ridges. They separate them into distinct segments and can run across for hundreds of kilometers

7. New faults form as they move away from the ridges. Mid oceanic ridges are formed when the plates move apart, pushing the seafloor outwards and along with that, the transform faults. When new crust however overlaps the transform fault, they stop moving against each other, and start moving side by side, creating a crack.

8. Transform faults increase in size as long as the plates continue to move. The areas of transform faults, especially in the surface create earthquake faults.

9. Faults at the surface can be part of a larger underground system. Some faults can cut across continental crusts. These faults are created by different geological processes, like compression stress from convergent boundaries, tension stress from divergent boundaries, and shear stress from transform boundaries.

10. Fault zones are areas where you can find different faults formed, relatively close to each other. The faults in fault zones can be shallow or deeper like the fault zone Sierra Madre.
