Answer:
Nonmetals typically combine to form covalent compounds.
Explanation:
The octet rule states that the atoms of the elements bond each other in the attempt to complete their valence layer with eight electrons. That is to say, the atoms will tend to yield or share electrons to complete eight electrons in the valence layer.
In other words, the objective is to have the closest noble gas electronic configuration, thus having the last complete electron layer and acquiring stability.
The covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule. Covalent bonds are established between non-metallic elements. These elements have many electrons at their outermost level (valence electrons) and tend to gain electrons in order to comply with the octet rule mentioned and be stable. The shared electron pair is common to the two atoms and holds them together.
Then, nonmetals typically combine to form covalent compounds.
Answer: ionic bonds can form between nonmetals and metals, while covalent bonds form when electrons are shared between two nonmetals.
Explanation:
7. Based on the principle of inclusions, the cobbles in conglomerate must have been formed _______ the conglomerate.
8. Geologists use the principle of _______ to justify using fossils in a sample of sedimentary rock to determine the rock’s age.
9. Partings between adjacent beds of sedimentary rock may represent periods of _______, which could range from a few decades to a few centuries.
10. Some graded beds, especially those resulting from deposition by a fast-moving debris flow, are reversed, which means _______ material is at the top instead of at the bottom.
Answer:
Explanation:
5. Limestone typically doesn't accumulate in the ocean at depths below 4,000 meters because below that depth, calcite is ___not preserved ____.
The calcite compensation depth CCD is the depth at which the rate of dissolution of calcite increases beyond that of accumulation.
6. Based on the principle of original horizontality, geologists conclude that layers of sedimentary rock that have been tilted must have been subjected to __tectonic forces_____.
Tectonic forces causes changes in a particle terrain
7. Based on the principle of inclusions, the cobbles in conglomerate must have been formed __earlier than_____ the conglomerate.
The principle of inclusion states that the inclusion is older than the rock that contains it.
8. Geologists use the principle of __fossil and fauna succession _____ to justify using fossils in a sample of sedimentary rock to determine the rock’s age.
The principle of fossil and fauna succession was credited to Williams Smith and it is used for relative dating of a sedimentary sequence. Here, fossils of plants and animals are used to date a sequence.
9. Partings between adjacent beds of sedimentary rock may represent periods of __unconformity _____, which could range from a few decades to a few centuries.
An unconformity is a period of non-depsotion or erosion within a rock layer.
10. Some graded beds, especially those resulting from deposition by a fast-moving debris flow, are reversed, which means ___the oldest____ material is at the top instead of at the bottom.
From the principle of superposition of strata, we know that the oldest layer is at the bottom of the sequence and the youngest is on top.
Answer:
1. high energy
2. deposition
3. Silt
4. limestone
5. Soluble
6. tectonic forces
7. before
8. principle of faunal succession
9. non deposition
10. coarser
(and no it doesn't give any options, it can be any device you can think of that uses a Convex lense)
Answer:
Explanation:
Convex lens is the lens which is used to converge the rays of light after refraction.
When the rays of light are coming parallel to the principal axis then after refraction they goes from the focus.
It is used as rear view mirror in automobiles. In this case it pelroduces small and erect image of faroff objects.
It is used in spectacles using for hypermetropia.
It is used in microscopes and telescopes.
Our eye also have a convex lens which forms images on retina.
A. you're able to pull through facing out
B. you're able to park farther away from the building
C. you're able to reverse out of the parking spot
D. they are located in a parking garage
Option (A) is correct
Straight-in spaces can leave you a safer out if you're able to pull through facing out
Straight-in parking is a method to park a vehicle where the vehicle is guided and parked safely in between the guiding lines.
Each car is provided a separate slot for parking. It thus helps to prevent blockage of cars. Each car can move in and out freely without any congestion.
Straight-in parking is the most traditional approach of parking which saves time for drivers, allows for two-way traffic as well.
The driver can line up from multiple angles. But the safest way to leave out the Straight-in parking is to pull through facing out.
So option A is the most suitable option in the provided case.
