How does a sundial does not work?
A sundial may not work when it is placed in a location with limited sunlight, such as in a shaded area or during cloudy weather. Additionally, inaccuracies can occur due to changes in the sun's position throughout the year and variations in the sundial's alignment. Finally, improper calibration or design flaws can also lead to incorrect time readings.
Why can't you tell the time on a sundial all year long?
You need direct sunlight to use a sundial, so it cannot be used at night or when clouds or pollution are diffusing the sunlight too much to create shadows.

How much time is needed to make a sundial move a ten degrees?
The time needed for a sundial to move ten degrees depends on the specific location and time of year due to the changing position of the sun in the sky. Generally, it can take about 40-60 minutes for a sundial to move ten degrees.
What might be problems with sundials?
Sundials rely on sunlight to function, so they are not accurate on cloudy days or at night. They may also require frequent adjustment due to the Earth's changing position relative to the sun throughout the year. Additionally, inaccuracies can arise from variations in the sundial's orientation or location.
Does a sundial change everyday?
The sundial itself doesn't really change day to day, or even year to year. They are generally fixed to the Earth and are not, in general, portable. The shadow cast by the "gnomon" (the pointer of the sundial) does move moment by moment throughout the day, and slightly from day to day.

Is throughout an adverb or an adjective?
Yes. The word "throughout" is an adverb. It can also be used as a preposition (e.g. throughout the year).
What did the ancient egyptians invent to keep track of records?
They invented the 365-day calendar. They used the Sun to keep track of the days throughout the years. They divided the year into 3 seasons of 4 months. Each month had 30 days. Their year had 360 days. The ancient Egyptians also used shadow clocks. The first ones were obelisks. The moving shadows formed a kind of sundial to help tell time. The sundial was then used very often since.

Why is sundial not completely reliable?
A sundial is not completely reliable because of the angle of the sun toward the earth at certain times of the year. It is also not perfectly reliable because of cloud covering that can obscure the readings.

When did sundials first originate in history?
It is not known exactly when Sundials first originated. There are records indicating that some type of sundial was used around the year 700 BC. The Greeks were introduced to sundials in 560 BC. But the exact date they were first used in not known.
