<span>Scienists determined that PLATE TECTONICS form and shape land masses here on earth.
The movements of these plates cause earthquakes, as well as create volcanoes and form mountains.
There are three types of known plate tectonic boundaries. These are 1) convergent boundary (when two plates come together), 2) divergent boundary (when two plates move away from each other), and 3) transform plate boundary (when two plates slides past each other).

Answer:
Crossing over
Explanation:
The onset of meiosis is characterized by shortening and thickening of genetic materials to form visible threads. Thereafter, homologous chromosomes pair up to a 4-chromosome structure known as tetrad.
The paired homologous chromosome then go ahead to exchange portions of chromosomes in a process known as <em>crossing over of genetic materials.</em>
Answer:
Axon hillock
Explanation:
Neuron or nerve cell is excitable cell of the nervous system which consists of cell body or soma (karyon), dendrites and an axon. Dendrites are short, numerous filaments responsible for the signal receiving. On the other hand, axon is long ant it originates form the cell body from the swelling called axon hillock. At the end of an axon there are axon terminals from which neuron can transmit a signal another cell.
It's a tissue. An organ is a group of different tissues which (though they perform slightly different functions), work together in the same general processes.
