Answer: is expanding

Explanation:

A supernova is a stellar explosion that occurs as a result of the final stage of a star's life. This event can be very remarkable, even observable to the naked eye. This means that supernovae are characterized by very intense flashes of light that can last from several weeks to several months. In addition, its luminous intensity increases rapidly until it reaches an absolute magnitude greater than the rest of the galaxy, and then gradually loses its brightness until it disappears completely.

Then, a supernova is a very bright element, however, as its distance from the observer is greater, they will be less luminous (look fainter). This is presented as proof that we live in <u>a universe that is expanding</u> and is not flat.

JulijaS [17]

Answer:

Yes.

Explanation:

In this region we see that faulting has occurred. Because the rock strata are not lined up with one another across the entire region, it is clear that the land has faulted and the the two edge blocks have slipped downwards leaving the middle block uplifted or that the middle block has been pushed upwards.

These two types of faulting are called normal faulting and reverse faulting. They are the result of tension and compression stresses, respectively, that pull and compress the rocks creating fractures called faults. If the stress is sufficient, the outer blocks slide downward or the middle block is uplifted.

The many volcanoes located along the edge of the Pacific Ocean make up the Ring of Fire. How does subduction play a role in the
sertanlavr [38]
<span>The most volcanically active belt on Earth is known as the Ring of Fire, a region of subduction zone volcanism surrounding the Pacific Ocean. Subduction zone volcanism occurs where two plates are converging on one another. One plate containing oceanic lithosphere descends beneath the adjacent plate, thus consuming the oceanic lithosphere into the earth's mantle. This on-going process is called subduction. As the descending plate bends downward at the surface, it creates a large linear depression called an oceanic trench. These trenches are the deepest topographic features on the earth's surface.

</span>
<span>The crustal portion of the subducting slab contains a significant amount of surface water, as well as water contained in hydrated minerals within the seafloor basalt. As the subducting slab descends to greater and greater depths, it progressively encounters greater temperatures and greater pressures which cause the slab to release water into the mantle wedge overlying the descending plate. Water has the effect of lowering the melting temperature of the mantle, thus causing it to melt. The magma produced by this mechanism varies from basalt to andesite in composition. It rises upward to produce a linear belt of volcanoes parallel to the oceanic trench, as exemplified in the above image of the Aleutian Island chain. The chain of volcanoes is called an island arc. If the oceanic lithosphere subducts beneath an adjacent plate of continental lithosphere, then a similar belt of volcanoes will be generated on continental crust. </span>

what is the name of the soil that forms in envrionments with extreme wet and dry seasons? hint: deep cracks form in this type of
ycow [4]

The soil that occurs in regions with extreme wet and dry seasons is known as "black soil."

Black soil:

  • Chernozem is another name for black soil.
  • It is largely composed of humus, phosphoric acid, phosphorus, and ammonia.
  • Exceptionally small or clay-like particles constitute black soils.
  • Deep gaps form during warmer weather, resulting in appropriate aeration.

Black soil characteristics include:

  • It is extremely fertile and has a clay-like texture.
  • At 25°C, the pH of black soil ranges from 7.2 to 8.5.
  • The soil has high levels of potash, calcium, and magnesium but low levels of nitrate and phosphate.
  • It is often soft when damp but hardens as it dries.
