What is the Earth's umbra?

What are the parts of the earths shadow?
The three parts of Earth's shadow are the penumbra (outer part where the Earth partially blocks the sun's light), the umbra (inner, darker part where the Earth completely blocks the sun), and the antumbra (an outermost region when an object appears larger than the sun as in a solar eclipse).
When the Moon's shadow hits earth or earths shadow hits the moon then what occurs?
During a lunar eclipse, Earth's shadow falls on the Moon, causing it to darken and sometimes appear red in color. During a solar eclipse, the Moon passes between Earth and the Sun, casting a shadow on Earth and blocking out the Sun partially or fully for an observer within the path of the shadow.
Is the shadow of the moon always long enough to reach the Earth?
No, the shadow of the moon is not always long enough to reach the Earth. During a solar eclipse, the moon's shadow on Earth is limited to a specific region where the alignment of the sun, moon, and Earth allows for the shadow to be cast on the Earth's surface.
What is the outer portion of the shadow cast on Earth by the Moon called?

Why can't earth's shadow have only an umbra and not a penumbra?
Actually the earth's shadow has both. This is caused by the sun, not the earth. The umbra is the dark shadow produced when the sunlight is totally blocked. The penumbra is the partially lit shadow produced because the sun is not a point light source.

What are the two regions earth's shadow during an eclipse?
There are actually three identified shadow regions in an eclipse; Umbra, penumbra, and antumbra.The umbra is the region where the light is totally obscured.The penumbra (partially shadowed) is the region of partial eclipse - the light is diminished, but not totally.The antumbra is that rather more distant region in the Umbra, where the light source may be perceived as a circle. A lesser known term.
