Which of the following best describes what must have happened in the past in an area with a large petroleum trap?
A.
Organic matter must have been buried and placed under intense heat and pressure until it became petroleum. Then, the petroleum must have collected inside an impermeable underground rock formation.
B.
Organic matter must have been exposed to intensely cold temperatures until it became petroleum. Then, the petroleum must have moved up to the Earth's surface through permeable underground rock formations.
C.
Permeable underground rock formations must have allowed the movement of organic matter deep into the Earth. Then, the organic matter must have been exposed to freezing temperatures until it formed petroleum.
D.
Impermeable underground rock formations must have blocked the movement of organic matter through the Earth's surface. Then, the organic matter must have decomposed to form petroleum inside the rock formations.

Answer:

A. Adding another bulb will make the two of them light a little less brighter since the electrical flow is divided into two making them work.

B. There is a possibility that the flow of electricity maybe little due to the thickness of the wire. There could also be a rise in the temperature of the cell and the bulb.

C. The Bulb will shine brighter because of the extra power or electricity provided! Also, if the voltage is too much, expect the bulb to burn out or sadly, explode.

The lines in an element's atomic spectrum result from

electron spins going in opposite directions.

energy that is spread out among an atom's electrons.

electrons moving from a lower to a higher energy level.

electrons moving from a higher to a lower energy level.

Answers

i think the answer is D sorry if i’m wrong.

The lines in an atomic spectrum indicates the transition of electrons from  higher energy level to the lower energy level. Hence, option d is correct.

What is atomic spectroscopy?

The investigation of the electromagnetic radiation that atoms absorb and release is known as atomic spectroscopy. Atomic spectroscopy, specifically the electromagnetic spectrum or mass spectrum, is used to determine the elemental compositions of substances since distinct elements have distinctive spectra.

Depending on the type of spectroscopy being utilized or the atomization source, it can be divided. The primary distinction in the latter instance is between optical and mass spectrometry. Although substantially more difficult, mass spectrometry typically provides significantly higher analytical performance.

Electrons can migrate between orbitals, but doing so requires them to either absorb or emit energy equivalent to the difference in energy levels between the quantized orbitals of their respective atoms.
