What is a galaxy?
a collection of stars
6 of 20
How old is the sun?
5000 million years old
7 of 20

sandstone, marble and granite.
10 of 20
Name 3 different types of waves
microwaves, x-rays, visible light, tidal, infrared, gamma waves, UV.
11 of 20
Name the 2 types of waves

12 of 20
an example of a transverse wave.
all electromagnetic waves- water waves.

14 of 20
explain why lower layers within the rock must be older.
layers must have formed over time, the lowest layers must have formed first to be at the bottom, meaning they are the oldest.
