Answer:
A solar eclipse can occur only when new moon occurs close to one of the points (known as nodes) where the Moon's orbit crosses the ecliptic. ... Therefore, the Moon's apparent size varies with its distance from the Earth, and it is this effect that leads to the difference between total and annular eclipses.
Explanation:
In Earth’s history before the Industrial Revolution, Earth’s climate changed due to natural causes not related to human activity. Most often, global climate has changed because of variations in sunlight. Tiny wobbles in Earth’s orbit altered when and where sunlight falls on Earth’s surface. Variations in the Sun itself have alternately increased and decreased the amount of solar energy reaching Earth. Volcanic eruptions have generated particles that reflect sunlight, brightening the planet and cooling the climate. Volcanic activity has also, in the deep past, increased greenhouse gases over millions of years, contributing to episodes of global warming

Answer: To clean the exterior and keypad of the microwave.
Explanation:
It is proper to clean the exterior of the microwave including the keyboard. Although this isn't required to be done daily, Benjy saw his mum do it at the time she decided to clean it (maybe it was stained too) and being a child he picks up the act too.
It is advisable to clean not only the interior of your microwave but the exterior top including the keypad. Cleaning the keypad prevents dirt and dust from staying in them and causing the keypads to get stuck.
I hope this helps
