WWK The differences and similarities between our moon
WWK The differences and similarities between our moon and the earth, as well as its history.
• The same side of the moon always faces earth because the moon takes the same length of time to rotate once as it does to travel all the way around the earth. • Only 59% of the Moons surface is visible. • http: //www. youtube. com/watch? v=OZIB_leg 75 Q
• The multi layer space suits worn by the astronauts to the moon weighed 180 pounds on earth, but 30 pounds on the moon due to the lower gravity. • Because the force of gravity at the surface of an object is the result of the object's mass and size, the surface gravity of the moon is only onesixth that of the Earth. The force gravity exerts on a person determines the person's weight. Even though your mass would be the same on Earth and the moon, if you weigh 132 pounds (60 kilograms) on Earth, you would weigh about 22 pounds (10 kilograms) on the moon.
• On July 20, 1969, Neil Armstrong became the first man to step onto the surface of the Moon. • Dr. Eugene Shoemaker’s ashes were placed on board the Lunar Prospector spacecraft on January 6, 1999, which was crashed into a crater on the moon on July 31, 1999. • When Alan Sheppard was on the moon, he hit a golf ball and drove it 2, 400 feet, nearly one half a mile.
Because the surface of the moon has no wind or water, an astronaut’s footprint could last forever for millions of years. January 30, 2006: According to Apollo 17 astronaut Gene Cernan. Moon dust feels soft like snow, doesn’t taste half bad, and smells like spent gunpowder. Some ancient peoples believed the moon was a bowl of fire, while others thought it was a mirror that reflected Earth's lands and seas, but ancient Greek philosophers knew the moon was a sphere orbiting the Earth whose moonlight reflected sunlight. The Greeks also believed the dark areas of the moon were seas while the bright regions were land, which influenced the current names for those places — "maria" and "terrae, " which is Latin for seas and land, respectively.
• The legendary scientist Galileo was the first to use a telescope to make scientific observations of the moon. • In 1988 there was a survey conducted that said 13% of those people thought the moon was made of cheese.
The moon's gravitational pull on the Earth is the main cause of the rise and fall of ocean tides. The moon's gravitational pull causes two bulges of water on the Earth's oceans. One where ocean waters face the moon and the pull is strongest and one where ocean waters face away from the moon and the pull is weakest. Both bulges cause high tides. As the Earth rotates, the bulges move around it, one always facing the moon, the other directly opposite. The combined forces of gravity, the Earth's rotation, and other factors usually cause two high tides and two low tides each day. • http: //www. youtube. com/watch? v=r. RPt. NAA 9 UE&feature=related
