A city that is adjacent to a warm ocean current will have ______ mean yearly temperature than a city at the same latitude that is adjacent to a cold ocean current.

Answers

The city's temperature will experience a cooler mean yearly temperature than the other city adjacent to a cold ocean current.

Warm currents cause more evaporation and more rain in the coastal areas. Usually, coastal regions stay cooler during summer than during winter. They are also warmer in winter. This situation moderates the temperature within the mean range.

Thus, the temperature range for the city adjacent to a warm ocean current will be cooler.

A hexagon has different side lengths and angle measures. The top and bottom sides are equal, and the left and right sides are equal. The top 2 angles and bottom 2 angles are equal, and the left and right angles are equal.
At which angle will the hexagon rotate so that it maps onto itself?

60°
90°
120°
180°

Answers

Answer:

The answer is 180°

Explanation:

For a hexagon to rotate unto itself, the shape after rotation and relative length and angles is identical to the original figures.

Since this hexagon is irregular i.e has sides of different lengths, and from the facts given, opposite sides and angles are equal.

This implies top/bottom, left/right and sides and angles 180° apart are identical.

Hence, only a 180° rotation will yield an identical hexagon.

Answer:

180!

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.
