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.
It is called a solar eclipse when the Moon's shadow hits Earth, and a lunar eclipse when Earth's shadow hits the Moon.
The outer incomplete shadow formed during an eclipse is called the penumbra. This is where the sun's light is only partially blocked by the blocking object, resulting in a partial shadow being cast on Earth.
Aristotle believed that the Earth was spherical in shape because of the observed curvature of its shadow during a lunar eclipse, the way ships disappear over the horizon, and the circular shape of the Earth's shadow on the moon during a lunar eclipse.
An eclipse of the sun throws the shadow of the moon onto Earth.
The earth's shadow falls on the moon only during a lunar eclipse. Eclipses of the moon can have varying degrees of totality. The earth's penumbra (partial shadow) may pass over the moon, or the umbra (full shadow) may pass over some or all of the moon's surface. All of these happen only at the time of full moon. The moon's regular phases are NOT caused by earth's shadow on the moon, as is incorrectly believed by some.
During a solar eclipse, the shadow falls on Earth as the Moon blocks the Sun's light from reaching specific areas. This creates a temporary darkening of the sky and can be observed from the regions where the eclipse is visible.

The Earth is larger than the Moon.

Lunar
That is a total eclipse of the sun.
lunar eclipse
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.
During a lunar eclipse, the moon is in Earth's shadow.
