The primary goal of the mission was to study thenear-Earth asteroid 433 Eros from orbit for approximately one year. ... Some scientists claim that the ultimate goal of the mission was to link Eros, an asteroidal body, to meteorites recovered on Earth.

Answer:

The NEAR Shoemaker was a space probe designed by the Johns Hopkins University Applied Physics Laboratory for NASA. The Shoemaker was the first space probe of the Discovery program.

The space probe was used to study Eros asteroid for a year. The spacecraft made 230 revolutions around Eros, before landing on 12 February 2001. The research provided new insights into the size, composition, mineralogy, gravity, morphology, internal mass and the magnetic field of Eros. This data was used to gain more insight into asteroids and comets in general.

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.

Which does not affect the amount of destruction caused by earthquake vibrations?

Soloha48 [4]

ANSWER:

The answer is A. If the structure of a building is built with earthquake-resistant materials, it does not affect the amount of destruction caused by earthquake vibrations.

EXPLANATION:

Especially in the countries that are prone to an earthquake, houses and building should be carefully planned and built in order to withstand an earthquake.

The bricks should be held in place with the right mortar. Also, the base of the building should be made stronger rather than the top floors.

Steel-framed buildings and good pillared buildings also tend to survive powerful quakes and vibrations.
