Answer:A) Can form ozone and block some UV radiation

Explanation: Ozone layer is made up of three oxygen atoms,it is formed as a result of the break down of oxygen in the high atmosphere by Ultraviolet radiation from the Sun,it will break an oxygen molecule into two parts and this will now combine with oxygen molecule available in the atmosphere to form OZONE( combination of three oxygen atoms). Ozone layer is the shield which helps to reduce the direct impact of the Sun radiation from aversely affecting the Earth.

the characteristic of projections which portray accurate sizes but distort shapes of land masses is called ____
denis23 [38]

Answer:

equivalence

Explanation:

Recall that this principle is the basis of Albert Einstein's theory of general relativity. According to the German researcher, gravity is not a force that acts independently on each object, but rather a deformation of the same temporal space tissue.

According to the test carried out now by the team of astronomers, these three dead stars in two of their forms, a pulsar or a white dwarf, are perfect candidates to confirm the theory.

The equivalence was already understood centuries ago by Galileo Galilei. In his famous test of the spheres in the Tower of Pisa he demonstrated the existence on Earth. Subsequently, astronaut David Scott did the same on the lunar surface in 1971.

Now, this team has demonstrated it by studying two of the densest objects in the universe. Until today, many believed that the high density of the pulsar made him exempt from complying with the equivalence principle. However, being subjected to the gravitational field of one of the white dwarfs, the closest and least massive, after six years of observations, they have been able to demonstrate that both bodies have the same acceleration. And, if there is a difference, it is less than three parts between one million. That is the conclusion reached by a new test that tested Einstein and corroborated his theories once again.

When geologists conclude that the Grand Canyon sequence of rocks was formed through hundreds of millions of years of deposition,
Delicious77 [7]

Answer:

D) uniformitarianism; the geologic processes that operated in the past are the same as those that operate today, and they occurred in accordance with the same laws of nature that are operating today

Explanation:

When geologists conclude that the Grand Canyon sequence of rocks was formed through hundreds of millions of years of deposition, mountain building, and erosion, they are basing this conclusion on the principle of <u>uniformitarianism </u>which states that <u>the geologic processes that operated in the past are the same as those that operate today, and they occurred in accordance with the same laws of nature that are operating today</u>.

Uniformitarianism is a theory in geology which states that the changes in the earth's crust during geological history is as a result of actions of uniform and continuous processes, that the geological processes occurring currently are same processes that have been occurring in history and every part of the world and is continuous.

When an oceanic plate collides with a continental plate, the continental plate usually slides up and over the denser oceanic pla
KengaRu [80]
The correct answer is B Subduction. Subduction is the process by which an oceanic plate gets dragged under another plate and is eventually destroyed in the mantle. Subduction occurs at convergent margins where two oceanic plates collide or an oceanic and Continental plate collide. Oceanic crust is made of mainly of silica and magnesium which is heavier or denser than continental crust which is composed mainly of silica and aluminium.
The subducting plate melts producing excess magma giving rise to volcanoes along these margins.
