Answer 1

In Earth's lowest rock layers, the fossilized organisms that are most likely to be found are bacteria. This is because bacteria are some of the oldest life forms on Earth, and they existed long before more complex organisms such as snails, reptiles, and dinosaurs appeared. Fossils of bacteria and other simple microorganisms are often found in the oldest rock formations.

Answer 2

A model shows that the moon has grown to twice its size, yet it has remained in the same place. In 1-2 sentences, explain how this would impact the gravity between Earth and the moon. Hint: Use the terms mass and distance in your response.

Answer 3

If the moon were to grow to twice its size while remaining in the same position, its mass would also increase. Since gravitational force depends on both the masses of the two objects and the distance between them, the increased mass of the moon would result in a stronger gravitational attraction between the Earth and the moon, assuming the distance remains constant.
