Planets and moons have different geological compositions. The moon contains a small metallic core and a weak magnetic field. The moon’s poor atmosphere causes its geology to be much different from a planet’s. The moon’s absence of an atmosphere causes there to be no signs of weather. Therefore, the moon’s texture did not come from weathering or erosion, but cratering and volcanism. Mercury’s geologic activity is very similar to the moon’s. Similarly to the moon’s surface, Mercury is covered in craters and large areas of lava, due to the geological activity. Mercury has a metallic like, iron nickel center. Although Mercury’s magnetic field is not as strong as that of Earth’s, it does have one. Venus and Earth are remarkably alike when it

The objects in the solar system each have their own traits through their composition, geologic activity, interior structure, and make ups of magnetic fields.
Earth’s volcanism is greater than the moon’s volcanism. Volcanoes can form on any solid planet or moon that contains lava, rocks, and volcanic gasses. The process of a volcano takes place when these materials erupt and break the the surface of the moon or planet. This produces volcanic rock and magma that add to the body’s surface. Volcanoes on Earth are located differently than the moon’s volcanoes. Volcanoes on Earth form within the mountains, and volcanoes on the moon form in craters. The moon’s volcanoes have been discovered to be exceptionally older than the volcanoes on Earth. The moon’s volcanoes are so old that the moon is sometimes viewed as a dead planet because of it’s lack of geologic activity. Earth’s volcanoes are much larger than those on the moon. Earth’s volcanoes are greater simply because Earth’s gravity is greater. The weak gravity on the moon causes the eruption of lava during the moon’s volcanoes to be slow and weak. A large factor of Earth’s large, explosive eruptions is water; because the moon lacks water, its volcanoes can not get as big or

In addition to the temperature and pressure raising, the form of hydrogen also changes; in the center of Jupiter, hydrogen transforms from a gas to a liquid. These changes cause the gases to draw away from each other, forming layers in the planet and atmosphere.
Jupiter’s chemical composition makes it to be the largest planet. Ceres is the largest body in the asteroid belt, but its makeup is very different from Jupiter’s. Ceres has a hard, rocky core compared to Jupiter’s. The next layer of the dwarf planet is thought to be made up of large bodies of water just below the icy mantle. The planet’s surface is thin and dusty, containing clay, water ice, and carbonates. Jupiter’s chemical composition is much different from that of Ceres’s.
Through studying the other bodies and planets in the solar system, it seems to me that
Earth is the perfect place for us to live. Earth’s composition includes everything we, or the planet, may need to be able to keep functioning. Our planet does not contain too much, or too little of anything. Our planet supplies us with water and oxygen. Being at the perfect distance from the sun so all of our water is not boiled into a gas or frozen into ice. This positioning in
and Metamorphic rocks can be found. There are also a lot of crusted plates, and violent
Basalt forms due to the partial melting of the layer of the mantle called the asthenosphere. The asthenosphere is the plastic zone of the mantle beneath the rigid lithosphere. Mantle plumes coming from the mesosphere can cause the asthenosphere to melt with heat or even if pressure decreases, which is called decompression melting (Richard 2011). The magma that forms from this melting is mafic magma that solidifies once it reaches the earth’s surface and cools quickly. The above process mainly occurs mainly during intraplate igneous activity which is the main explanation for volcanic activity that occurs a long distance away from a plate boundary. If the tectonic plate above the mantle plume is moving it can create a string of volcanic activity such as in Hawaii. See Fig 2.
From modern examples and records we know that volcanic activity can set of a chai...

Super volcanoes are formed when magma rises from the mantle to create a scorching reservoir in the Earth's
Volcanoes are one of natures most interesting and dangerous phenomenons. The way volcanoes operate can be understood, on a basic level, by just some simple physics and chemistry, this paper will investigate and explain some of the basic physics that govern the behavior of volcanoes.
Volcanoes can be one of the most destructive forces on Earth. It is estimated that some
There are five basic theories in the formation of our moon. The first is the "fission theory" which states that the moon was once a part of earth, but separated a long time ago. The second theory is called the "capture theory". This theory is says that the moon formed somewhere else, and was "captured" by earths gravitational pull. The third theory is called the "condensation theory" this theory states that the moon and earth were condemned together from the original nebula that formed our solar system. The fourth theory called the "Colliding Planetesimals Theory" states that the interaction between the earth orbiting the sun, and the sun orbiting planetesimals, which are large Astroid like rocks, led to the breakup and formation of our moon from the debris of these planetesimals. The fifth and final theory is called ...
Magnetic Field: The Earth has a superior magnetic field due to a core consisting of iron and nickel. Currently the rotation of the Earth and its Coriolis effect help to create this pull of the tides from the oceans. The northern lights or lurora Borealis can be seen at various times in a mystifying view of beauty.
The gas giants are a collection of planets in our solar system. As can be told from their name, they are mostly composed of differing mixtures of gases and ices. The gas and ice composition in question varies among the different planets. This mix of gases gives much of the planets an extremely thick atmosphere. At the very center of a gas giant is a core of liquid heavy metals. The gas giants are also called Jovian planets, taken from the largest planet in our solar system: Jupiter. Due to the fact the the majority of a gas giant planet is gas, the planet isn’t very dense and therefore, very large as a result. In fact, all of the gas giants are vastly larger than all of the terrestrial planets. Another common factor of the gas giants are their large amount of moons. The terrestrial planet, Mars, has the largest amount of moons, 2. The amount of moons of Mars is dwarfed in comparison to Saturn’s and Jupiter’s moo...

...lieve that millions of years ago, a piece of rock as big as Mars hit the Earth, and the collision blasted a huge amount of rock into space, and the shattered pieces of rock went into orbit around the Earth. Over millions of years, the rocks clumped together to form the moon, and now it is not the pieces of rock that orbit the Earth, but the moon itself. Scientists, Native Americans, and many other people have their theories of how the moon became, but none have been proven. Scientists have studied the moon for many years, and have proven many theories, but not this one.
The gravitational forces between the Earth and the moon cause some interesting effects; tides are the most obvious. The moon has no atmosphere, but there is evidence by the United States Department of Defense Clementine spacecraft shows that there maybe water ice in some deep craters near the moon's North and South Pole that are permanently shaded. Most of the moon's surface is covered with regolith, which is a mixture of fine dust and rocky debris produced by meteor impact. There are two types of terrain on the moon. One is the heavily cratered and very old highlands. The other is the relatively smooth and younger craters that were flooded with molten lava.
