Question

Ammonite fossils, an ancient marine mollusk,

Answer 1

1. G. the rocks that became the Himalayas were once at the bottom of an ocean

The fact that we see fossils of marine animals such as ammonite and marine mollusk in Nepal, high in the Himalayan Mountain Range, is a good proof that the continents have been moving and that that has caused significant changes in the topography. The Himalayas came to be because of the collision of the Indian plate and the Eurasian plate. The Indian plate moved toward Eurasia, and as it did it was closing down the ancient Tethys Ocean. The crust started to lift up as the two plates started to press against each other, so what was once ocean floor started to come above the surface and slowly turning into high mountain range, moving the marine fossils with it.

2. F. new moon

When the Moon is located between the Earth and the Sun we have the new moon lunar phase. During this phase we can actually not see the Moon from the Earth as it appears totally dark, so it blends in with the night sky. The reason why the Moon appears totally dark from the Earth's perspective is that the half facing the Earth is covered from the sunlight, thus it is not lighted, while the other half that is facing the Sun is entirely lighted because it is exposed to the sunlight.
