Astronomers use light years to measure distances in space because space is so massive and distances so far that conventional numbering is inadequate and unmanageable. One light year is a distance measurement equivalent to six trillion miles.

Scientists use the light year instead of astronomical units to measure the distance between stars because the distance between stars is very large and the use of light year is more efficient to express large distances. Measurement in light year is also easy to understand. The use of astronomical units is not practical. A light-year is the distance traveled by light in one year in an empty space. 1 light year = 9.4605284 × 10^12 kilometers.

Which statement explains how convection currents affect the movement of plates? Gravity pulls one edge of a plate down into the
ArbitrLikvidat [17]

Convection currents direct the movement of Earth's rigid tectonic plates in the planet's fluid molten mantle.

In places where convection currents rise up towards the crust's surface, tectonic plates move away from each other in a process known as seafloor spreading.

So, I would say the answer is:

As convection currents drift across the oceans,

they bring the pieces of Earth's crust with them as the supercontinent breaks apart.

Glad I could help, hv a good day :)

Mrac [35]

The small, almond-shaped organs of the female reproductive system, suspended by ligaments in the upper lateral portion of the pelvic cavity are known as ovaries.

Ovaries are oval-shaped so are also termed almond-shaped organs and are present on the sides of the uterus in females. In females, the processes of pregnancy and ovulation which is also termed menstruation are controlled by the hormones that are made by ovaries. These hormones include estrogen and progesterone. Another major function of the ovary is that it releases the female gametes known as eggs during the menstrual cycle.

The ovaries are attached to two types of ligaments which are the ovarian ligament and suspensory ligament. Ovaries are connected to the womb by the ovarian ligament while the suspensory ligaments of the ovary contain the ovarian vessels and nerves.
