Why does earth's shadow often covers the entire moon during a lunar eclipse but only only a small part of the moon's shadow during a solar eclipse?

During a lunar eclipse, the Earth is positioned between the Sun and the Moon, causing the Earth's shadow to fall directly on the Moon. The Earth's shadow is large enough to cover the entire Moon due to its size and the distance between the Earth and Moon. Conversely, during a solar eclipse, the Moon is positioned between the Earth and the Sun, casting a smaller shadow on the Earth. The Moon’s shadow is much smaller because it is significantly smaller in size compared to the Earth, leading to only a partial coverage of the Earth's surface.
