Its speed is not always constant; because of its orbit, it sometimes goes faster or slower. However, its appearance changes because of where it is compared to the earth and sun - when the sun shines on part of it, that part is visible, but where it is in shadow, it is not visible.
The Moon's orbit is an ellipse, sort of an oval. It is basic orbital mechanics that when the satellite (in this case, the Moon) is closest to the primary (in this case, the Earth) it is moving fastest. This point of closest approach is called "perigee". As the Moon continues in its orbit, it is getting further away and slowing down, until it reaches "apogee", its furthest distance, and it begins to move closer and speed up.
Anything with constant velocity is moving at a constant speed in a straight line.
Neither of these characteristics describes the motion of the moon.
There is no evidence whatsoever that it does not. There are huge amounts of data supporting the concept that earth orbits the sun.
For the same reason that the earth's distance from the sun is always changing. The orbits are elliptical and not circular. Virtually all orbits in the solar system are elliptical, Pluto's being the most extreme of the major and minor planets. Some of the moons come close to having no eccentricity.
There is only one force acting on an orbiting spacecraft ... the force of gravity.It's NOT correct to say that a constant speed in a curved path indicates balanced forces.That's true only when the constant speed is in a straight line. If the direction is changing,there must be net forces on the moving object, even if its speed is constant.
The moon changes phases because different portions of the moon are illuminated by the sun, as seen by observers on Earth. The angle formed by the sun, the Earth, and the moon, is constantly changing as the Earth orbits the sun and the moon orbits the Earth.
It stays consistent (:

The Earth orbits the sun. While it orbits, the Earth spins on its axis. When the Earth spins, some part is always facing the sun, but some is not. This constant spinning creates day and night.
It always moves it orbits the Earth which orbits the sun.
When the Earth orbits the sun different sides of the earth face the sun.Therefore changing the temperature.
Yes. The Earth, our Sun and indeed all planets, stars and galaxies are in constant motion.
The climate everywhere remains in a constant state of flux. It is always changing. It Texas, as across most of earth, the climate is currently changing substantially faster than by any strictly natural means.
No because it stays in orbit and takes pictures of the ever changing earth.

Centrepetal force-orbits E.G. Earth orbits the sun at a constant speed but also changes its direction, thus its velocity. This means that the almost constant change in velocity causes there to be a constant acceleration because of the change on direction.
