Final answer:
A solar eclipse during the summer in the Northern Hemisphere happens when the new moon phase coincides with the Earth's orbit around the Sun, leading to the Moon blocking the Sun's light either partially or fully for certain Earth locations.
Step-by-step explanation:
A solar eclipse occurs when the Moon passes between the Earth and the Sun, and the Moon fully or partially blocks the Sun. During the summer in the Northern Hemisphere, the North Pole is tilted towards the Sun, experiencing longer daylight hours. If during this time, the new moon phase aligns directly with the Sun, a solar eclipse can be observed from some parts of Earth. During a solar eclipse, the Moon casts two types of shadows on Earth: the darker umbra, where a total eclipse is visible, and the lighter penumbra, where a partial eclipse is visible.
An annular eclipse occurs if the Moon is too far from Earth to completely cover the Sun, resulting in a bright ring surrounding the darkened Moon. The dotted lines around the model would represent Earth's orbit as it revolves around the Sun. When the new moon phase coincides with the summer solstice around June 21, if the alignments are correct, an observer located on Earth at the right position would witness a solar eclipse.
