Deep ocean currents are driven by density and temperature gradients. Thermohaline circulation is also known as the ocean's conveyor belt (which refers to deep ocean density driven ocean basin currents). These currents, called submarine rivers, flow under the surface of the ocean and are hidden from immediate detection.
The light-colored material is in areas of the Moon called the highlands, which represent the earliest crust on the Moon. Impact cratering shattered this crust and often deformed it, pushing some of it into mountain-high impact crater rims or ejecting it across the surface of the Moon.
Share this set. As the Moon journeys from New to Full, the proportion of its illuminated side visible from Earth is (increasing/decreasing). This is known as (waxing/waning). As the Moon journeys from Full to New, the proportion of its illuminated side visible from Earth is (increasing/decreasing). This is known as (waxing/waning). The New Moon is highest in the sky to an earthbound observer at (noon, sunset, midnight, sunrise). The Full Moon is highest in the sky to an earthbound observer at (noon, sunset, midnight, sunrise). Throughout the Lunar Cycle, the Moon will appear further (eastward, westward) in the sky at the same time each day. Therefore, to an earthbound observer, the time of day when the Moon is highest in the sky becomes progressively (earlier, later).
