Which factors are involved in earthquake formation? Check all that apply. plates moving rocks breaking stress that decreases fau
AfilCa [17]

The correct answers are:

- plates moving;

- breaking rocks;

- movement bellow the surface;

The earthquakes are a direct result of the plate tectonics. In order for an earthquake to appear, there should be a geologic activity caused by the movement of the tectonic plates. The movement of the tectonic plates causes a lot of pressure on the rocks. The rocks eventually break at certain places under the pressure. A they break, there's movement bellow the surface, or rather inside the crust, also referred to as adjustment. That movement and the release of power from it, causes lot of strong vibrations. The vibrations spread out and start shaking the ground in the surrounding area, which is actually the earthquake itself.

Name the tissue that water travels up from the roots to shoots in a deciduous tree.
Leviafan [203]

The tissue that water travels up from the roots to shoots in a deciduous tree is xylem.

<h3>What is xylem?</h3>
  • Xylem is one among the two types of transport tissue in vascular plants, the opposite being phloem.
  • Transport water from roots to stems and leaves is the main function of xylem, but it also transports nutrients.
  • The word xylem springs from the Ancient Greek word ξύλον (xylon), meaning "wood"; the best-known xylem tissue is wood, though it's found throughout a plant. The term was introduced by Carl Nägeli in 1858.
  • The long tracheary elements are the most distinctive xylem cells that transport water. Tracheid and vessel elements are distinguished by their shape; vessel elements are shorter, and are connected together into long tubes that are called vessels.
