A college student has been assigned to write captions for a new textbook on gravity and motion. This is one of the pictures from the textbook. Which caption best describes the thinner arrow?
The moon moves toward the Sun due to gravity.
The moon would not stay in orbit without the pull of Earth's gravity.
The moon will move away from Earth because of inertia.

Why is relative dating important when approximating the age of Earth?
Scientists can identify different life forms using index fossil records.
Scientists can examine how temperature changes within Earth’s interior.
Scientists can determine the order of when rocks formed on Earth.
Scientists can analyze changes in chemical concentration of atmospheric gases.

in the middle
on top
on the side
A geologist finds some tilted sedimentary rock layers. Which conclusion can the geologist draw by looking at the rock layers?
The youngest layer was originally deposited as the bottom layer but a geologic event flipped them.
They were originally deposited horizontally but a geologic event displaced them.
Their absolute age is 600 million years.
They were tilted before they were deposited

Carson is on vacation at the Grand Canyon and is looking at some rock layers. He notices that some rocks have horizontal layers, while others have vertical layers. What is the likely cause of this difference?
Vertical layers formed originally and a geologic event shifted the layers into a horizontal position.
Layers formed vertically and then the earth's rotation and tilt caused the layers to shift.
Layers formed horizontally and then the earth's rotation and tilt caused the layers to shift.
Horizontal layers formed originally and a geologic event shifted the layers into a vertical position.
Which correctly lists three materials that preserve soft tissues in fossils?
sediment, minerals, and amber
minerals, permafrost, and amber
permafrost, amber, and tar
amber, minerals, and sediment
__________ cannot be preserved in a fossil.
bone
hair, skin, and nails
soft tissue
all of the above
none of the above
