What is long trails of ejecta?

What is long trails of ejecta?

long trails of ejecta that radiate outward from a Moon crater. They are visible as light-colored streaks. occurs when the Moon passes directly between the Sun and Earth and blocks our view of the Sun.

What are the long trails of ejecta that radiate outward from impact craters on the Moon?

Some craters have long trails of ejecta, called rays,that radiate outward. Rays are vis- ible as light-colored streaks, as shown in Figure 28-8B.

What are the mountainous regions on the Moon called?

In addition to giant craters and sweeping lava fields, the moon is home to some pretty massive mountains. Up there, the mountains are referred to as massifs. New charts of the lunar south pole revealed the towering nature of two such massifs: Malapert Massif and Leibniz Beta.

What are smooth dark plains on the Moon called?

mare, plural maria, any flat, dark plain of lower elevation on the Moon. The term, which in Latin means “sea,” was erroneously applied to such features by telescopic observers of the 17th century.

What is the name for the material blasted out on impact of the Moon?

The Moon is coverered with a gently rolling layer of powdery soil with scattered rocks that is called the regolith; it is made from debris blasted out of the Lunar craters by the meteor impacts that created them. Each well-preserved Lunar crater is surrounded by a sheet of ejected material called the ejecta blanket.

What is loose ground up rock on the Moon’s surface?

regolith. Layer of loose, ground-up rock on the lunar surface. prduced by the moon getting hit by micro meteorites.

What are seas called on the Moon?

lunar maria
The lunar maria (/ˈmɑːriə/; singular: mare /ˈmɑːreɪ/) are large, dark, basaltic plains on Earth’s Moon, formed by ancient volcanic eruptions. They were dubbed maria, Latin for ‘seas’, by early astronomers who mistook them for actual seas.

What are the layers of the Moon?

Scientists have used information from lunar rocks and other measurements to figure out what is inside the Moon. Beneath its thin coating of crushed rock, the Moon has three layers—a crust, a mantle, and a core. As on Earth, the crust is the outermost layer.

What is the name of the tallest mountain on the Moon?

Mons Huygens
Mons Huygens is the Moon’s tallest mountain. Its height is 18,046 ft – more than half the height of Mt. Everest! The mountain is named after Christiaan Huygens, a Dutch astronomer who discovered Titan, Saturn’s largest moon.

Are there mountains on the surface of the Moon?

The moon has neither tectonic plates nor volcanic action. Virtually all of its mountains are the result of impacts by asteroids in the distant past. The mountain ranges and individual mountains are labeled with their Latin names, “montes” for mountain ranges and “mons” for individual mountains.

What is a long narrow valley on the surface of the Moon?

A rille is a long and narrow valley on the Moon and appears to have been formed by subsidence or collapse of surface materials along a crustal fracture (Baldwin 1968), which could be ascribed to the thermal and mechanical erosion, construction, and volatiles between the basement surface and a surficial permafrost layer …
