Olympus Mons is a volcano located on Mars that is around three times larger than mount Everest. The height is a difference from Earth and Mars. There are a few other volcanoes near Olympus Mons called Arsia Mons, Ascraeus Mons and Pavonis Mons.
Olympus Mons is shaped with the slopes being highest near the middle and become emptier near the bottom making it not symmetrical. The lava does not shoot up, instead it slowly moves down.
Arsia Mons: a shield with a low slope and a huge caldera at its summit that has a fan like shape. A caldera is formed when a magma room is emptied which ends in either a sudden explosive shooting up and out of matter of lava, or explosion and collapse of the magma room roof.
Asctaeus Mons: Its inclines are most steep in the center part of the flanks, leveling out toward the base and close to the top where a wide summit level and caldera complex are found (Ascraeus). It is encompassed by runny magma that streams surrounding it.
Pavonis Mons: a shield that has a very low profile with flank slopes; summit contains a deep, circular caldera, with a larger, shallower

The northern marshes are the floor of an enormous hole after a gigantic effect hit Mars quite a while back. The crustal polarity is the edge the cavity, since a long time ago adjusted in different ways.The southern locales are not marshes but rather good countries, that were unaffected by the effect. The main exemptions are territories like Hellas and argyre, which are themselves affect bowls, but much littler than the huge northern one. We realize that the Hellas Planitia is one of the most established surfaces on Mars, in light of the fact that the bowl is thought to have been shaped amid the Late Heavy Bombardment time of the Solar System billions of years back when a substantial space rock hit the surface. Affect cavities and changed by volcanism has been most imperative in forming Southern Highlands on
Yes this feature is the result of erosion and depositional processes however, it is not associated with the current water course. This feature may be the result of a Gilbert type delta that once occupied this area. Gilbert type deltas have three main components; topsets, foresets and bottomsets. Topsets are fluvial sediments (primarily sandur deposits) that were deposited on the subaerial delta surface. Erosive events occurring on the upper forslope can result in downslope channels and chutes. These features are then eroded by either strong currents or by debris flow resulting in these channels and chutes to become filled. Foresets are a combination of sand and gravel facies. The are deposited by gravitational processes on the delta foreslope and the grains tend to become finer and more angular downslope. Bottomsets consist of fine grained silts and clay and are deposited at the foot of the delta front.
...e morphed it into the quartzite that is seen surrounding the butte (4). Rocks that undergo this process are called metamorphic rock, which is the same as the rock seen years ago by dinosaurs and other extinct creatures. The quartzite rocks were formerly seafloor sediment that was forced upwards, and then surrounded by lava basalt flows. Once erupted through fissures and floods through out most of the area, lava flow eventually created enough basalt to form a thickness of about 1.8 kilometers (1). All of this basalt flow eventually led to the covering of most mountains, leaving the buttes uncovered. The igneous lava flows and loess is reasons that the Palouse consists of such sprawling hills, and rich soil for farming (2). In result of the lava flows, the Precambrian rock Quartzite was formed. And lastly covered by the glacial loess, which were carried by the wind.
and Metamorphic rocks can be found. There are also a lot of crusted plates, and violent
Lassen Peak, also known as Mount Lassen, is the southernmost active volcano in the Cascade Range. It is part of the Cascade Volcanic Arc which is an arc that covers southwestern British Columbia to northern California. Located in the Shasta Cascade region of Northern California, Lassen rises 2,000 meters above the surrounding terrain and has a volume of 0.5 cubic miles, making it one of the largest lava domes on Earth. It was created on the destroyed northeastern side of now gone Mount Tehama, a stratovolcano that was at least 1,000 feet higher than Lassen Peak.
Mount Rainier is a volcano that is located in the Cascade Range in Mount Rainier National Park, Washington. This volcano is 14,411 feet (4,392 meters) in its elevation. This is the highest mountain in Washington. This volcano is in the same mountain range as Mount Adams, Mount Baker, Mount St. Helens and Glacier Peak. It is known as a stratovolcano which is a large, steep volcano built up of alternating layers of lava and ash or cinders. This volcano is an active volcano and the last time it erupted was in 1894. The largest eruption this volcano has had was 2200 years ago. It has been recorded that the areas has had a lot of small high-frequency earthquakes. Some of them occur daily. According to geologist the cause of this is hot fluids moving inside the mountain. It is composed of two overlapping volcano crater that are 1000 ft. around. This volcano has three different summits; they are Columbia Crest, Point Success and Liberty cap, the highest which is 14,411 feet and the lowest which is 14,112 feet. It lies on the Juan de Fuca Plate. This is a divergent boundary. It was formed by the subduction of the Juan de Fuca Plate and the North American Plate. This volcano also has lahars which are large mudflows that happen in the deposits of sediments that surrounds volcanoes; they can be hot or cold. This volcano includes but not limited to the rock andesite.
Later after the sea finally retreated occurred volcanic activity. Mountains rose through laccoliths, which also resemble volcanoes. These laccoliths differ in that they do not erupt. They shifted layers of rock upward in the shape of a dome. This specific piece of geologic morphology occurred at the end of the Cretaceous time. This marked the beginning of the Laramide Orogeny, which was a well-known period of mountain formation in western North America.
First, one must know a little information about this volcano. Mount Shasta is located in Siskiyou County, California. This volcano is the second highest peak in the southern end of the Cascade Range and is still active, though not enough for people to notice. At 14,179 feet it is also the most voluminous stratovolcano located in the Cascade Volcanic Arc. The mountains complex shape is due to the four overlapping volcanic cones it consists of, including the most prominent, main summit, Shastina. The other cones include: Sargents Ridge cone, Misery Hill cone, and Hotlum cone. Sargents Ridge cone is the oldest of all the cones that make up the mountain. Though it is now dissected by a glacial valley, a portion of it can still be seen on the mountain. Misery Hill makes up a large part of the present mountain. the fourth cone, the Hotlum cone is formed from eruptive products and is located on the northeastern side of Mount Shasta. Three of the four major vents on the mountain are aligned with a north trending zone that passes through the mountains summit. This linear alignment parallels local faults, which suggests that the bedrock structure has influenced and partially controlled the dimensions in which Mount Shasta develops (Mie...
Volcanoes. The naturally forming landforms that can look remarkably beautiful. Gentle slopes, or high rising heights with snow caps and greenery that seems to attract many tourists and sightseers around the world. These magnificent landforms can also cause major destruction and can produce forces that can explode, burn, and create a great deal of damage. Two of these extravagant wonders of the world is the Mount Saint Helens composite volcano in Washington, US, and the Mauna Loa shield volcano in Hawaii, US. These landforms have a eruption history of many colors. One has a great power in eruption, but another has a eruption that is quiet and gentle. In comparing these two volcanoes there are many likes, and dislikes, to consider. So the following
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
The Mauna Loa volcano is located in Hawaii and means "Long Mountain" in Hawaiian. It is a giant, basaltic shield volcano. It is one of the largest volcanoes and mountains in the world and has been called the "monarch of mountains". It has an estimated volume of 9,600 cubic miles and takes up half the land of Hawaii. It extends about 120 km starting from the southern tip of the island to the northern region. It is 97 km (60 miles) long, 48 km (30 miles) wide, and is 8,742 km (28,680 miles) high from the base on the sea floor to the top. The slopes are steeper than 12 degrees and about 4 degrees at the top of the volcano. Mauna Loa formed about half a million years ago and in the middle stages of forming into a shield volcano where lava flows to form a sloped and broad flat domed volcanic cone. Along with Mauna Kea, the Mauna Loa volcano is responsible for the creation of the Hawaiian Islands. Mauna Loa has erupted thirty-three times since 1843 and is known as one of the most active volcanoes in the world today. The last eruption was 1984 and lava flowed within 4 miles of the city of Hilo. This shows that it is dangerous to live anywhere near Mauna Loa and that it poses as a threat to anyone living near it because it has a very high possibility of erupting within a very short span of time. Below is a picture of Mauna Loa taken from a bird's eye view.
The older of the two, Ancient Greece was a civilization for three centuries, from 800 B.C. to 500 B.C. Ancient Greece advanced in art, poetry, and technology. More importantly, Ancient Greece was the age where the polis, or city-state, was invented. The polis was a defining feature in Greek political life for a few hundred years (Ancient Greece).
Volcanoes are formed when magma is expelled from the Earth’s surface, resulting in volcanic eruptions consisting of ash and lava. Over time, the lava cools and forms into rock on the Earth’s surface. Whenever an eruption occurs, the newly-formed rock from the lava layers continuously until the volcano takes its shape. Volcanic eruptions have taken place for thousands of years, and even today, according to the U.S Geological Survey (2010), there are approximately 1500 active volcanoes located throughout the world.
inferred for the reservoir (4). The magma ascent to the surface occurred through a conduit of possibly 70 to 100 m in diameter (5). A thermal model predicts that such a reservoir should contain a core of partially molten magma (6) that can be detected by high-resolution seismic tomography.
