How is amplified warming different from natural warming

1 answer:

4 0

The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. Normal warming is mostly caused by natural gases.

Question 9 (1 point) Igneous rocks can form under many different conditions, but they are always the result of cooling and cryst

Ugo [173]

Answer:

A.True.

Explanation:

Igneous is the Latin word for a rock that means fire, this is formed through the cooling and solidification of magma and lava the magma and lava form crystal on their process of cooling and hence if the magma cools quickly the crystals made will be small and bigger crystal are formed when it cools slowly.

It crystallizes as the natural gas comes in contact with the molten lava. These rocks also come in a variety of geological settings such as shields, platforms, orogens, basins, and extended forms of crust and oceanic crust.

Igneous rocks are thus called primary rocks and thus there are 700 known igneous rocks on earth and hence divided into two categories of rocks such us intrusive or plutonic rock being crystallized from magma beneath the surface of the earth and Extensive rocks like the volcanic rocks that are crystallised from the lava at the surface of the earth.

Scientists find trilobites during a routine dig. Trilobites were common in the Paleozoic Era (540 to 245 million years ago) and

kifflom [539]

Answer:

A and C

Explanation:

The rock layers must have formed at different times because they contain two different biozones. The rock layer containing the trilobites must have formed before the one containing the ammonites. The key thing to note here is that the Trilobites only lived from 540 to 248 million years ago. And that the Ammonites were from 245 to 65 million years ago. So there's a 3 million year gap between these 2 different creatures where neither of them existed. So the dig where the trilobites were found has to be at least 3 million years older than the dig where the Ammonites were found. So with that in mind, let's look at the options and see what makes sense.

The rock layers must have formed at the same time because they both contain biozones. * This is nonsense no matter what dates you're speaking of. In effect it claims that all rocks that indicate life were created at the same time. So this is definitely a bad choice.

The rock layers must have formed at different times because they contain two different biozones. * This is technically incorrect since it assumes that all biozones represent an unique period of time which is incorrect. However, since the biozones represented by the presence of Trilobites and Ammonites don't overlap, it is true that these these rock layers were formed at different times. I would have preferred if this option said "non overlapping biozones". But on the balance, I'd consider this option to be true, so it should be selected.

The rock layer containing the trilobites must have formed before the one containing the ammonites. * This is definitely true since the last Trilobite died about 3 million years before the first Ammonite lived. So this is a correct choice.

The rock layer containing the trilobites must have formed after the one containing the ammonites.

* This is the opposite of the previous option. And since the previous option was true, this option must be false. So this is a bad choice

Mariana [72]

Answer:

Fault- B

Extrusion- H

Unconformity- G

Relative Age- E

Law of Superposition- C

Intrusion- D

Absolute Age- A

Index Fossils- F

Explanation:

Fault- A fault generally refers to the fracture as a result of which either the hanging wall goes up or down with respect to the footwall. it takes place either due to compressional or extensional stress. In simple terms, it is a break that occurs in the earth’s crust.

Extrusion- These are the consolidated rocks that are formed when magma comes out to the surface forming extrusive rocks. For example, Basalt and Rhyolite.

Unconformity- It is defined as the period of non-deposition. It occurs when the rocks surfaces are eroded extensively. These are the surfaces where the much older rock meets geologically younger rocks.

Relative age- When the age of any rock is compared with the age of different rocks then, the relative age of the rock is obtained. It is extensively used for the calculation of the age of rocks from any sedimentary sequence.

Law of Superposition- This law enables us to evaluate the relative ages of two or more rocks as it depicts the younger rocks that are deposited on the apex and the older rocks at the bottom of a sequence.

Intrusion- These are the rocks that form due to the crystallization and solidification of magma beneath the earth's surface. For example, granite and gabbro.

Absolute age- This refers to the total amount of time (in terms of years) that a rock has formed. These rocks are formed from the deposition, compaction, and lithification of sediments in a sedimentary environment.

Index fossils- These are the fossils that were present for a shorter period of time and have a wide geographical distribution and were mostly used by the geologists in order to match the rock layers.

Tems11 [23]

It seems that you have missed the given options for this but anyway, here is the correct answer. The Atlantic Ocean is currently growing wider as its floor enlarges due to the process of sea-floor spreading. In sea-floor spreading, pieces of oceanic crust MOVE APART ALONG A DIVERGENT PLATE BOUNDARY.
