Geologic activity is basically the internal and external processes and events that affect a planetary body. Geologic activity forms different things on planets specifically Earth. Water, ice, wind, weathering, erosion all are factors in geologic activity. One recent study that has found geologic activity on the moon was the Lunar Reconnaissance Orbiter (LRO). The LRO showed the Moon’s crust being stretched, forming valleys in some small areas on the lunar surface. Scientists believe that the moon is in a general state of contraction because of cooling of a still hot interior. The weak contraction suggests that the Moon, unlike the terrestrial planets, did not completely melt in the early stages of its evolution.
The four smaller inner planets, Mercury, Venus (Links to an external site.), Earth (Links to an external site.) and Mars (Links to an external site.), are terrestrial planets (Links to an external site.), being primarily composed of rock and metal. The four outer planets are giant planets (Links to an external site.), being substantially more massive than the terrestrials. The two largest, Jupiter and Saturn (Links to an external site.), are gas giants (Links to an external site.), being composed mainly of hydrogen (Links to an external site.) and helium (Links to an external site.); the two outermost planets, Uranus (Links to an external site.) and Neptune (Links to an external site.), are ice giants (Links to an external site.), being composed mostly of substances
Saturn has an average radius of nine times that of Earth, it is the second largest planet after Jupiter and sixth from the sun.
Jupiter is the largest and the fastest spinning planet in our solar system. The storm on Jupiter known as the Great Red Spot could swallow up the entire Earth. Jupiter is made primarily of hydrogen and helium and has no solid surface. Its atmosphere resembles that of the sun. Stathopoulus (2000 – 2011), “ Sixteen moons have been identified, with Ganymede noted as the largest - it is bigger than both Mercury and Pluto” (Facts about Jupiter, para. 9).
One of these terrestrial planets, Mercury is the topic of the next section. Mercury, one of the smallest planets, has a surface similar to that of a moon because it is cratered with some smoother areas. However, it is distinct from the moon in that the plains are the same color as the cratered areas. Mercury
Although all nine planets are a huge part of the solar system there's a lot more to the solar system than the nine planets. According to scientist the Solar System started out as an enormous cloud of gas and dust. Scientist believe that the cloud of dust and gas began to collapse under the weight of its own gravity and it did. The matter that was kept within itself began moving in a giant circle and at the center of the spinning cloud a tiny star began to form. The star eventually grew larger and collected more dust and gas that collapsed into it. Farther from the center of the mass that was being formed there was many smaller clumps of dust and gas that were also collapsing. The large cloud in the center eventually became the sun while the smaller clumps formed the planets, moons, comets and,
The first, geo-processes is a volcano. Volcanoes happen when when the plates underneath the volcanoes move creating the the magma to push up until the pressure is too much and it erupts. Scientists have an idea that the volcano is going to erupt soon when earthquakes happen near the volcano. A volcano creates mountains and mountain ranges. The article The Hills Are Alive talks about the movement under the volcano. “While the volcano was inactive, the land on top of it was being pushed together by surrounding geology keeping the magma bubbles sealed”. That quote shows how the land was moving closer because of the plates underneath.
Geology is the study of the Earth’s crust through the crust’s chemical composition and physical properties. The way that geologists are able to figure out the
The rings made up of millions of ice crystals,some as big as house and others as small as specks of dust saturn is very light as it is made up of more hydrogen
Jupiter, being the fifth and largest planet from the sun, is huge. In fact, it is approximately a thousand times the size of our home planet. Alongside Neptune, Saturn and Uranus, it is a gas giant. hydrogen and helium are the main components. Jupiter's surface appears striped due to the color swirls. wind on the planet gets up twice as strong as a hurricane on earth.
Saturn is the second largest planet in the solar system. Jupiter is the only planet that is larger. The gas giant is 72 thousand miles in diameter, almost ten times the size of Earth. In spite of its huge size, though, Saturn weighs very little. It is a very light gas planet. Saturn is the least dense planet in the solar system-- so light, in fact, that it would float in water. This planet is mostly composed of hydrogen and helium, like Jupiter, but it is much less dense. The combination of its light weight and fast rotation causes Saturn to spread out, or oblate, its center. Since Saturn is a gas planet, it does not have a solid surface. Spacecraft are unable to land on this type of surface. The clouds that are seen when looking at Saturn are just the top layer of a very deep layer that covers a center of liquid hydrogen. The clouds are blown by constant winds that reach speeds up to one thousand miles per hour at the equator of the planet (“Great Space Place”).
The Inner Planets are the planets that are closest to the sun. These planets include Mercury, Venus, Earth, and Mars, which are made of solid, dense rock. Even though these planets are composed of similar materials, they all have unique characteristics that set them apart from other planets.
There are many differences between the Terrestrial, Jovian, and Dwarf planets. The Terrestrial planets are the four inner planets that are closer to the sun which are Mercury, Venus, Earth, and Mars. These planets do not have a lot of atmosphere. They are little and dense. The Jovian planets are the opposite. They are big, have thick atmospheres, and are low density. There are three qualifications for something to be a planet. A Dwarf planet meets two of the qualifications. The first is that it orbits the sun. The second is that it a sufficient mass to make it spherical. The third is that it has cleared the area around its orbit. This last qualification is the one that Pluto falls short on, it has not cleared its orbit thus making it a Dwarf
Uranus and Neptune are distinctively bluer than Jupiter and Saturn, because Uranus and Neptune both have atmospheres that contain significant amounts of methane. Uranus's atmospheric composition is 2.3% methane, and Neptune's is 3% methane. Methane resides in the upper atmosphere of these planets, where the temperature is low. Methane and water condense to form ice crystals in the upper atmosphere, and because methane freezes at a lower temperature than water, methane forms the higher clouds in the atmosphere. Methane absorbs red light and scatters blue and green, giving these planets their blue-green color. In comparison to size, Jupiter and Saturn both contain a small rocky terrestrial core which is surrounded by liquid metallic hydrogen,
With The Planets, Op. 32, composed 1914-1916, Gustav Holst incorporates a wide array of cultural and scientific references to create musical characters for each of the planets in our solar system. The scientific connection is immediately clear simply by looking at how Holst chose to order the movements. While he does not specifically place the planets in order of distance from the sun, they still follow a pattern that clearly references their positions in space. Mars, Venus, and Mercury open the suite, being numbers 3, 2, and 1 from the sun (neglecting to count Earth, which does not appear). Following this are Jupiter, Saturn, Uranus, and Neptune, being numbers 4, 5, 6, and 7 in order. While an awareness of their scientific positions is
Mercury which is the planet that is closest to the sun is the first planet I will discuss. Mercury is the smallest of the inner
The terrestrial planets are Mercury, Venus, Earth, and Mars. These four planets are the planets that are closest to the sun. Terrestrial means earthlike; therefore, these planets are all earthlike because they have a solid ground. The terrestrial planets are the middle school years. The knowledge learned here orbits the sun. If the knowledge learned at the sun is not retained, a student may have a
