A) 62.5 grams
B) 100 grams
C) 125 grams
D) 250 grams
E) 500 grams
Why is part of the core of the Earth thought to be liquid?
S-waves cannot pass through the core
The density of the Earth is larger than the Moon
P-waves cannot pass through the core
The Earth must have incorporated a large abundance of liquid helium when it formed
Volcanoes in the Earth allow water to sink to the core
