its magnetic field?
A. Cilist
B. inner core

Answers

Answer

Outer Core

Because of the weight of the melting moving metal creates energy

Our planet is shielded from cosmic radiation and charged particles from our Sun by the magnetic field, which is created by the motion of molten iron in the Earth's core. It also offers the framework for compass navigation. Thus, option D is correct.

What role of outer core of earth in magnetic field?

Radiative heating and chemical differentiation have caused the Earth's outer core to be in a state of turbulent convection.

The convective kinetic energy is transformed into electrical and magnetic energy through a mechanism that is somewhat similar to a naturally occurring electrical generator.

The magnetic field is not produced by the earth's core, since metals lose their magnetic characteristics at high temperatures.

Therefore, Because of the weight of the melting, moving metal creates energy.

How are mid-ocean ridges formed at divergent tectonic plates?

The plates are moving in a zigzag formation, creating shallow earthquakes which forms a mid-ocean ridge.
Mid-ocean ridges are not resulting features of ocean-to-ocean divergent boundary zones.
The plates are moving towards each other, which causes the crust to buckle and push upwards or sideways which forms a mid-ocean ridge.
The stretching lithosphere is pushed up as the plates move apart.

Answers

Answer:

The stretching lithosphere is pushed up as the plates move apart.

Explanation:

Mid-ocean ridges are basically underwater mountains that are created with the help of lava convection (which causes the rising of plates) and the diverging (the pulling away) of tectonic plates. This is also how ocean floor spreading happens.

I know that mountains are formed by the converging of tectonic plates, but ocean ridges are NOT created like this.

dichotomous key of a cockroach​

Answers

Yo whsiqosbb Hsiang s Dianne. Dioxin

Answer:

Identification of cockroaches is limited here to  adults. A major source of confusion is the recognition of adults from nymphs.There are  subjective differences, as well as morphological  differences. Immature cockroaches are known as  nymphs. Nymphs closely resemble adults except  nymphs are generally smaller and lack wings and  genital openings or copulatory appendages at the  tip of their abdomen. Many species, however, have  wingless adult females. Nymphs of these may be  recognized by their shorter, relatively broad cerci  and lack of external genitalia. Male cockroaches  possess styli in addition to paired cerci. Styli arise  from the subgenital plate and are generally conspicuous, but may also be reduced in some species.  Styli are absent in adult females and nymphs

Now It’s time to build the infrastructure necessary to unlock the oil and natural gas trapped more than a mile below the ground. A well is drilled straight down into the ground beneath the pad.

What is oil extraction?

The process of oil extraction involves drilling wells into the earth and then using various techniques to bring the oil to the surface, and the first step in oil extraction is to identify a suitable location for drilling, which is typically done using geologic surveys and other exploration techniques to locate areas with the potential for oil reserves, next step is to complete the well by installing a casing that helps to prevent the well from collapsing. Technologies such as "hydraulic fracturing," which involves injecting water and sand and assisting in the release of trapped oil and gas, have recently gained popularity.

Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other.

Two of the strongest forms of chemical bond are the ionic and the covalent bonds. Chemical bonds form between two atoms, each with its own electron environment.

What is a resistance gene?

In order to survive, bacteria can create mechanisms known as resistance against antibiotics and antifungals. The germ's resistance mechanisms are determined by the specific proteins that DNA instructs the germ to produce. Many different forms of resistance genes can be found in bacteria and fungi.

Once a bacteria have acquired a resistance gene and incorporated it into its DNA, the bacterium can dominate other bacteria and convey the resistance gene to all of its offspring. Bacteria reproduce quickly, which amplifies resistance.
