The second molars on the top come in soon after those on the bottom. 3 years. Your child has a full set of 20 baby teeth. 4 years. Jaw and facial bones grow, creating space between the baby teeth for your child's permanent teeth to come in.
As the moon moves eastward around 13 to 15 degrees per day in the sky in its orbit about the earth (there are 360 degrees around the whole sky for it to complete its orbit in 27.3 days), it moves with respect to the background stars noticeably each day, causing it to rise nearly an hour later each day/night when compared to the previous day/night.
NEXT PAGENEXT. The following diagram shows how the moon causes tides on Earth: In this diagram, you can see that the moon's gravitational force pulls on water in the oceans so that there are bulges in the ocean on both sides of the planet. The moon pulls water toward it, and this causes the bulge toward the moon. The bulge on the side of the Earth opposite the moon is caused by the moon pulling the Earth away from the water on that side. If you are on the coast and the moon is directly overhead, you should experience a high tide.
