Answer:
17. Laccolith
18. Sill
Explanation:
A laccolith is formed when magma makes its way up a d-ike and lodges itself between sedimentary rocks. The successive flow puts pressure on the rock such that a dome like structure is formed.
Sills are like mini laccoliths but instead are much smaller and linear. They can appear on multiple layers as shown in the diagram above.

Answer: The greater the distance to a galaxy, the greater its redshift</h2>
When we talk about the <u>visible electromagnetic spectrum</u>, we know it starts in violet-blue and ends in red.
Now, in this context the astronomer Edwin Powell Hubble observed several celestial bodies, and when obtaining the spectra of distant galaxies he observed the spectral lines were displaced towards the <u>red</u><u> </u>(red shift), whereas the nearby stars showed a spectrum displaced to the <u>blue</u>.
From there, Hubble deduced that the farther the galaxy is, the more redshifted it is in its spectrum, and noted that all galaxies are <em>"moving away from each other with a speed that increases with distance"</em>, and enunciated the now called<u> Hubble–Lemaître Law</u>.
This means in the past the distance between two galaxies was smaller than at present, being this the proof that <u>the universe is expanding</u> (like a balloon expands when it is filled with air or another gas).
At this poitn it is important to stay clear that <u>the redshift is not produced by the relative movement of the galaxies with each other</u>. This effect is in fact, due to the <u>own expansion of the space</u> among the galaxies.
What statement you would need to include the information
The heaviest elements settled in the Earth's center during the formation of Earth's lithosphere
<u>Explanation:</u>
Earth's lithosphere comprises the crust and the uppermost mantle, which form the strong and rigid external layer of the Earth.
The Earth, on the other hand, begins with a core of iron and radioactive materials such as uranium and plutonium, which deliver energy in the form of heat, within a process known as nuclear fission. It passed by a fusion stage - a "liquid-pasty" state - which provided that, due to gravity, the more solid materials dropped towards the center, while the smaller ones floated towards the crust, a process called planetary differentiation.
