When strong solar winds are displaced poleward by our magnetic fields?
When strong solar winds are displaced poleward by our magnetic fields, we get: intense auroral displays. The oldest rocks on our crust are radioactively dated at about: four billion years old.
Why does the Moon show phases in the course of a month?
The moonlight we see on Earth is sunlight reflected off the Moon's grayish-white surface. The amount of Moon we see changes over the month — lunar phases — because the Moon orbits Earth and Earth orbits the Sun.
What is true of lunar highlands?
What is true of the lunar highlands? They are the oldest part of the lunar surface. they range from 4.6 – 4.4 billion years old, on average. the Moon lacks wind, water and an atmosphere.
Which moon phase has the lowest tide?
quarter moon phases During the quarter moon phases, the gravitational forces of the Sun and Moon are at their minimum, producing very small ranges of tidal highs and lows (neap tides). A neap tide is the lowest level of high tide; a tide that occurs when the difference between high and low tide is least.
Does the moon phase affect tides?
The phases of the moon also affect tides. When the moon is at its full or new moon phase, high tides are at their highest, while low tides are lower than usual. Called spring tides, these tides occur when the sun, moon and the Earth all line up.
At what lunar phase would the tidal variation be greatest?
When the moon is at its full or new moon phase, high tides are at their highest, while low tides are lower than usual. Called spring tides, these tides occur when the sun, moon and the Earth all line up. The added gravity of the sun can make the oceans bulge more than at other times.
What is a magnetosphere astronomy quizlet?
Magnetosphere. The region of space surrounding Earth, and is formed by the interaction of solar wind with Earth's magnetic field.
During which phase of the Moon do neap tides occur?
Neap tides occur during the first and third quarter moon, when the moon appears "half full."
During which moon phase do spring tides occur?
During the moon's quarter phases the sun and moon work at right angles, causing the bulges to cancel each other. The result is a smaller difference between high and low tides and is known as a neap tide.
Is there copper on the Moon?
But in terms of anything easily accessible, there is very little copper on the Moon. The Lunar Sourcebook is available in full online and for download, and has all the numbers from Apollo. Samples from Apollo remain the best resource for trace minerals like copper.
Are there cliffs on the Moon?
After more than six years in orbit and imaging nearly three-quarters of the moon's surface, LRO has detected more than 3,200 of these fault scarps. These cliffs are the most common tectonic feature on the moon, and are typically dozens of yards or meters high and less than about 6 miles (10 kilometers) long.
What phase of the moon has highest tides?
When the moon is at its full or new moon phase, high tides are at their highest, while low tides are lower than usual. Called spring tides, these tides occur when the sun, moon and the Earth all line up. The added gravity of the sun can make the oceans bulge more than at other times.
Where do low tides occur?
High tides occur in the locations closest to and farthest from the moon. Low tides occur in locations at 90 degree angles to the moon. Tidal cycles have the same length as the lunar day, 24 hours and 50 minutes.
What phase of the moon has the lowest tide?
quarter moon phases During the quarter moon phases, the gravitational forces of the Sun and Moon are at their minimum, producing very small ranges of tidal highs and lows (neap tides). A neap tide is the lowest level of high tide; a tide that occurs when the difference between high and low tide is least.
Which moon phase produces the highest and lowest tides?
Then the pull on the tides increases, because the gravity of the sun reinforces the moon's gravity. In fact, the height of the average solar tide is about 50 percent of the average lunar tide. Thus, at new moon or full moon, the tide's range is at its maximum. This is the spring tide: the highest (and lowest) tide.
How does the magnetic field interact with solar wind be sure to consider the magnetosphere the Van Allen radiation belts and the aurorae?
Be sure to consider the magnetosphere, the Van Allen radiation belts, and the aurora. The solar wind interacts with Earth's magnetic field, distorting it and pointing it away from the sun. Fortunately, the magnetic field deflects most of these solar-wind particles, so they don't reach Earth's surface.
What are the Van Allen belts quizlet?
In the Magnetosphere what are the Van Allen Belts? The Van Allen Belts are captured electrons in donut orbits about the Earth (two specific donuts) held in place by the Earth's magnetic field.
At which phase S of the moon do the highest and lowest tides occur?
Then the pull on the tides increases, because the gravity of the sun reinforces the moon's gravity. In fact, the height of the average solar tide is about 50 percent of the average lunar tide. Thus, at new moon or full moon, the tide's range is at its maximum. This is the spring tide: the highest (and lowest) tide.
What moon phases cause high tides?
The highest tides occur when the Moon is new or full. High tides sometimes occur either before or after the Moon is straight overhead.
Is it legal to mine the moon?
In 2015, the U.S. Congress and President Barack Obama passed legislation that unilaterally gave American companies the right to own and sell natural resources they mine from celestial bodies, including the Moon.
Is rust on Mars?
Mars has long been known for its rust. Iron on its surface, combined with water and oxygen from the ancient past, give the Red Planet its hue.
Who cracked the moon?
The splitting of the Moon (Arabic: انشقاق القمر) is a miracle in Muslim tradition attributed to the Islamic prophet Muhammad.
Can the moon have earthquakes?
The moon is still tectonically active, like Earth, generating moonquakes as our planet creates earthquakes, a new study based on Apollo mission data found. These moonquakes likely happen because the moon is quivering as it shrinks, researchers added.
Which phase of the moon has the lowest tide?
The Moon's current phase for today and tonight is a Waxing Crescent Phase. A Waxing Crescent is the first Phase after the New Moon and is a great time to see the features of the moon's surface. During this phase the Moon can be seen in the wester sky after the sun dips below the horizon at sunset.
Which moon phase has the lowest low tide?
first quarter moon Around each first quarter moon and last quarter moon – when the sun and moon are at a right angle to Earth – the range between high and low tides is least. These are the neap tides.
What moon phase is low tide?
During the quarter moon phase, the gravitational forces of the Sun and Moon are at their minimum, producing very small ranges of tidal highs and lows (neap tides).
What is neap tide?
A neap tide—seven days after a spring tide—refers to a period of moderate tides when the sun and moon are at right angles to each other.
What happens when Earth’s magnetic field interacts with the solar wind does Earth’s magnetic field protect the planet?
Earth's magnetic field serves to deflect most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. One stripping mechanism is for gas to be caught in bubbles of magnetic field, which are ripped off by solar winds.
What part of Earth’s magnetic field is the first line of defense to solar wind particles?
The magnetosphere The magnetosphere is the planet's first line of defense against the solar wind. Scientists knew that this plasma stream occasionally breached the magnetosphere near the equator, where the Earth's magnetic field is roughly parallel to the magnetic field in the solar wind.
