Here are your answers, hope they help!

Explanation:

Mechanical weathering is the breaking down of substances, often rocks, into smaller pieces. There is no molecular change. In chemical weathering, molecular change occurs. Molecular change means that a few of the atoms that create the molecule could become unattached and separate; and some new atoms might be introduced into the mixture during this process. If mechanical weathering is the physical breaking down of a substance, and it breaks down into single molecules(remember, this doesn't change the molecule itself), the single molecules could join with other molecules and make new substances.

A slump is exactly what it sounds like: a large vertical slab of land that "slumps" and sags under the force of gravity. A slump does not move at quick speeds like a landslide. A landslide is composed of chunks of rock and dirt that move downhill, often at high speeds. The landslide often starts from a pile of loose dirt. It also can start when a mountain with partially solid rock formations undergoes an earthquake and rock pieces are shaken free of the loose formations. The image I've included shows the difference.

never [62]

Jaundice is a condition that causes the skin of a newborn baby to turn yellow. This happens so because babies are born with extra red blood cells. After birth, the extra red blood cells break down and release a substance called bilirubin in the baby's blood. When there is too much bilirubin in the blood, the baby becomes jaundiced. <span>This condition may last for </span>3-12 weeks<span> after birth, but as long as bilirubin levels are monitored and the baby is feeding well, it rarely leads to any serious complications.</span>

AlekseyPX

The correct answer is B. An electron orbital describes a three-dimensional space where an electron can be found 90% of the time.

Explanation:

Electrons are negatively charged particles found in atoms. These different from protons and neutrons are not located in the nucleus of the atom but orbit it. Additionally, electrons do not orbit the nucleus following a linear pattern but they have a wave-like behavior which means they move in a three-dimensional space or area known as electron orbital in which they can be found most of the time, this space of area is determined depending on energy, momentum, and other factors. Thus, an electron orbital is "a three-dimensional space where an electron can be found 90% of the time".
