What is the inner portion of the shadow cast on the Earth by the Moon in a solar eclipse?

The narrow central region of the eclipse shadow, where the Sun's disc is totally obscured, is called the umbra. Areas that only observe a partial or incomplete eclipse are in the penumbra. Another term sometimes used for annular eclipses, where there is no umbra, is the antumbra, where only a small ring of light remains around the Moon.

What is the lunar ecplise?
A lunar eclipse occurs when the moon passes through the Earth's shadow. The moon passes behind the earth and prevents the sun's rays from striking the moon. There are three basic types of lunar eclipses: 1. Penumbral Lunar Eclipse - when the moon passes through the Earth's penumbral (outer) shadow. This type of eclipse is very subtle and difficult to notice. 2. Partial Lunar Eclipse - when part of the moon passes through the Earth's umbral (inner) shadow. This type of eclipse is easy to see. 3. Total Lunar Eclipse - then the entire moon passes through the Earth's umbral shadow. The moon turns a red hue. A lunar eclipse can only occur during a full moon when the Sun, Earth, and Moon are aligned with the Earth in the middle.
What is the dark inner shadow where total eclipses can be seen on earth?
"Umbra" is correct. However, another way to look at it is that the darkest part of the Earth's shadow is midnight, for what is night but the shadow of the Earth?
What do you call it when the moon casts a shadow on the earth?
This is called a solar eclipse as the moon is blocking out the sun from your perspective on Earth. The actual shadow has two parts which both have their own names. The area that is the full shadow where you would witness a total solar eclipse is called the umbra. There is also a larger and less dark shadow that is cast around the umbra called the penumbra. In this area only a partial eclipse would be witnessed.It is a solar eclipse, or an eclipse of the sun. Only a small part of the earth's surface is darkened by the moon's shadow at any moment, and the shadow follows a path across the surface for as long as the earth, moon and sun are aligned closely enough.
What occurs whenever the moon phases through the earth's shadow?
MOSTLY true. When the Moon is COMPLETELY within the Earth's umbra, there will be a total lunar eclipse. (Whether you see the eclipse may depend on the weather!)The "umbra" is the darker central shadow of the Moon or the Earth. The "penumbra" is the lighter partial shadow. If only PART of the Moon is in the umbra, then there will be a partial eclipse.If the Moon goes through the penumbra without going through the umbra, then there will be a "penumbral" eclipse, but you probably won't see any difference at all; we generally cannot notice the partial shading of a penumbral eclipse without special instruments.
True or false the umbra is the inner part of the shadow?
The umbra in a shadow is the portion where light from a source is completely blocked. This is in the middle of the shadow. The area around this, where light from part, but not all of the source shines is called the penumbra. In the shadow cast by the moon in an eclipse, the penumbra is the partial shadow that occurs before the total eclipse, and the umbra is the 'total eclipse' portion
Is it true that the umbra is the inner part of the shadow?
Not precisely. The umbra is the TOTAL part of the shadow. In a total eclipse, where the eclipsing object is spherical, then the "inner" part of the shadow is the umbra, but in a partial eclipse, there IS NO umbra; just the "penumbra", the partial shadow.

What do you call the inner most portion of the Earth?
The core.
Does the earth have large molten core?
Earth has a two-part core. The outer portion is molten while the inner portion is solid.
