Label the components of the map.

Geologic Map of the Castle Dome Area, Gila County, Arizona

Answers

Based on our understanding of geological maps and their components, we can confirm that the empty labels, from left to right, correspond to "fault lines", "contact lines", and "strike and dip".

In geology, a fault is described as a crack or fracture across a rock. These faults serve to show a history of major displacement resulting from the movements of rock masses. These are displayed on geological maps as fault lines, like the one on the far bottom left of the image attached in the question, in the pink-colored area.

Contact lines, on the other hand, are a line that serves to mark the intersection at which a surface comes into contact with the surface of bedrock that lies under a mantle rock. This contact may be concealed or may appear exposed. This is marked on this geological map by the label in the light beige-colored region on the bottom right.

Strike and dip is a term that refers to the angle or orientation that a geologic element is shown in. The strike line for a geological feature represents the intersection of said element with the horizontal or base plane. This is marked by the empty label on the far right of the image, in the dark brown-colored area.

Please Help!!!!!How is the position of the full moon in relation to Earth and the sun different from the position of the full Venus in relation to Earth and the sun? Does the apparent size of the moon change with its phases? Please explain!!!!

Answers

Answer:

The Moon's phases arise from the relative positions of Earth, the Moon, and the Sun. Mercury and Venus, the two planets interior to the Earth, also go through a full range of phases. To understand how phases work, realize that only half of a spherical object can be in full sunlight at any given time. What phase we see just depends on how much of the lit hemisphere is visible to us. When an object is nearly between the Earth and the Sun, the lit hemisphere points away from us and we see only a thin crescent; this is "new Moon" or "new Venus". For "full Moon" or "full Venus", the object must be outside Earth's orbit or on the far side on the Sun

The relationship between the Earth, Moon, and Sun determines the phases of the Moon. The two planets closest to the Earth, Mercury and Venus, likewise experience a full spectrum of phases.

What is the concept of the passage?

Realize that a sphere may only ever have half of its surface in direct sunlight at any given time to comprehend how phases operate. It just depends on how much of the illuminated hemisphere we can view to determine what phase observed.

The lighted hemisphere of an object that is almost between the Earth and the Sun points away from us and we only see a slender crescent is known as the "new Moon" or "new Venus." The object must be on the far side of the Sun or outside of Earth's orbit in order to be considered "full Moon" or "full Venus."

Thus, The relationship between the Earth, Moon, and Sun determines the phases of the Moon.
