Which statement is true about the process of accretion?
a-it causes fragments of crust to disconnect and drift away from continental landmasses.
b-it results in embedded volcanic island arcs and microcontinents being left behind.
c-it reduces continental landmasses while forming mountains along the edges of continents.
d-it enlarges continental landmasses and forms mountains along the edges of continents.

Option (D)

Explanation:

When continental plates collides with one another, it forms a sandwich pattern, in which the rocks undergoes compression. As a result of which, the landmass rises, forming huge mountain ranges. This mountains so formed are bigger in size as well as in area. This materials get accumulated due to the plate tectonic movement. For example, the Himalaya.

According to the process of accretion, the continental landmass also increases in area and size due to the addition of materials by the weathering and erosion of the nearby rocks by the agents such as wind, ice and water.

Thus, the correct answer is option (D).

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle

sound moves fastest in solids because the molecules are tightly packed and it allows sound to vibrate
