What changes were most likely caused by a shift in earth's continents?
Blizzard [7]

Answer:

The earth’s crust is broken into separate pieces called tectonic plates (Fig. 7.14). Recall that the crust is the solid, rocky, outer shell of the planet. It is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. Both types of crust rest atop solid, upper mantle material. The upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

Each tectonic plate is free-floating and can move independently. Earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. The term fault is used to describe the boundary between tectonic plates. Most of the earthquakes and volcanoes around the Pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. Other observable results of short-term plate movement include the gradual widening of the Great Rift lakes in eastern Africa and the rising of the Himalayan Mountain range. The motion of plates can be described in four general patterns:

Collision: when two continental plates are shoved together

Subduction: when one plate plunges beneath another (Fig. 7.15)

Spreading: when two plates are pushed apart (Fig. 7.15)

Transform faulting: when two plates slide past each othe

Answer:

occurs in metaphase I - is random chromosome alignment resulting in variation.

occurs during sexual reproduction - fuses gametes to form offspring with genes from each parent

occurs in prophase I - exchanges genetic information between non-sister chromatids

Metaphase I is a stage of meiosis I during which chromosomes are randomly aligned at the metaphase plate. The chromosomes are randomly distributed into two daughter cells after meiosis I. Random segregation of chromosomes adds genetic variation in a population.

Sexual reproduction involves the formation and fusion of gametes. Each gamete is contributed by each parent. The fusion of these gametes results in the formation of a new combination of genes which are different from either parent.

Prophase I is the first stage of meiosis I during which the event of crossing over takes place. Crossing refers to the exchange of genetic material between non-sister chromatids of homologous chromosomes.
