Transcript: Book definition by Seth Abels Goodbye -------- by Seth Abels My definition Lava is =Liquid magma that has escaped from the earth's interior My question Get ready for my question! Thank you for watching If liquid magma came down the side of a volcano would it effect the outside of the volcano by burning it. 1 1 0 ------------ Hot magma that moved from the core all the way up to the surface 1 1 Thank you The miner had to move away from the volcano because lava was leaking down the side of it. My video __________ Lava _________/ Sentence 0 Hawaiian Lava Flow \
Transcript: Description and Purpose Other types of lava include pressure-ridge caves, spatter cone chambers, and blister caves. The buckled appear as ridges. The pressure-ridge caves can be formed beneath the ridges by the mechanical lifting of the roof rock.When ejected blobs of liquid freeze, fuse, and weld together. Trapped streams can lift lavas while it is still in a plastic state to form small blister caves. They are generated small, but some can be big. Description Sources Lava tubes are a type of volcanic caves. Lava tubes develop best from pahoehoe lavas. They barely form from aa lavas. The overflowing is directed in natural pathways first. The lava flows at a relatively high velocity in a narrow canyons. When the surfaces crusts over, the supply of pahoehoe lava is confined to a narrow channel. The combination of gases contains a high temperature and the walls of the cave into a black glaze. Volcanoes A Lava Cave forms as a result of solidification of a lava flow during the last stages of its activity. A dwindling supply of lava may then cause the molten material to drain out from under the crust to collect and leave cylindrical tunnels. "Lava." Britannica School.

Other Types of Lava Lava Tubes Sources Lava Cave Volcanoes are vent into the crust of a planet or moon which makes eruptions of molten rock, hot rock fragments, and hot gases. Eruptions can cause disastrous loss of life and property. Volcanos are evidence of a dynamic planet. Volcanos shaped the objects of the solar system, and they can transport materials from the interior of the object to the surface. The Science of Lava Description Made by: Brian Tran Lava is magma emerging as a liquid onto the Earth’s surface. The temperatures of molten lava range from around 700 degrees celsius and 1,200 degrees celsius. Mafic lavas are known as pahoehoe and aa. Their downslope often exceed 100 kilometers per hour. Lava rocks can be used for grilling and gardening. Lava rocks could also be used to heat up furnaces and ovens. Lava may be used as architecture as it give a valuable and symbolic feeling.

Transcript: Resolution When the female volcano rises from the sea she can't see the male volcano because her back is towards him and he is almost underwater. The exposition in "Lava" is that the volcano has a dream about having a significant other. But as he starts to go extinct and underwater he finds something he wouldn't ever think was true. Taylor Jasso The female volcano rises from the sea and realizes that the song hes been singing was meant for her. Jeanette Morales Rising Action Falling Action Lava Exposition The male Volcano can hear the Female volcano singing the song so since she can't see him he starts singing so she knows that hes there. Francisco Lomeli As they sing together, the male volcano gets happy and erupts and rises out of the water. This presentation is by... Conflict The Male volcano was very happy to know there was another Volcano emerged from the sea to be with. He had found his significant other. Celine Cuevas Climax

Transcript: Volcanoes MAGMA Pictured here is a volcanic eruption in hawaii CAUSES OF ERUPTIONS MAGMA TO LAVA Historic Volcanic Eruptions The crater from the destruction that mount st helens left. HOT SPOTS AND FAULTS Some volcanoes are located at hot spots and other are located at fault lines. Mount Vesuvius Mt. Saint Helens Mt. Etna Mt. Kohala Mt. Mauna Kea Another cause is from earthquakes Describes the large scale motions of Earth's lithosphere. The buoyancy and the pressure of the gas within the earth’s crust cause the volcano to erupt. Magma is melted iron and nickel that is in a liquid form, then cools down to form land. VOLCANIC LOCATIONS PLATE TECTONICS The way that magma changes to lava is that plates seperate which is a convergent boundary.
Transcript: GOAL! Lava is molten rock that has been extruded onto Earth's surface. Before it reaches the surface, lava is called magma . Magma contains crystals , unmelted rock, and dissolved gasses, but it is primarily a liquid. Oxygen , silica, aluminum , iron , magnesium, calcium, sodium, potassium, titanium, and manganese are the primary elements found in magma, but other trace elements may be present in small amounts. weathering lava Lava is molten rock that has been extruded onto Earth's surface.

Transcript: lava :) Around the World lava by Charlotte Barwick 1 what is lava ? lava is heated rock , geothermal energy and expelled through fractures planetary crust. why does lava get so hot? lava gets really hot because of the pressure and radiogenic heating which makes it hot deep in the earth. About 100km down in the earth where the rocks melt to make magma. what happens when cold is added to lava? As lava cools is turns into solid rock this is caused because of the cooling of the lava because it cant stay hot in a cold climate. what happens to lava when it cools down #1 volcanoes aren't just found in random places on earth because of the earths crust is broken into a series of stabs known as tectonic plates. this effects where volcanoes are found and where they are most dangerous. why are volcanoes found in places but not others #2 Elements in lava! silicon Potassium oxygen phosphorus aluminum titanium iron magnesium calcium sodium these elements are in lava many more elements are found in lava much these are the ones mostly found in lava. Elements of lava #3 lava is created beneath the earths surface in places that temperatures get hot, hot enough to melt rock lava:) #4 http://volcano.oregonstate.edu/how-lava-formed https://www.scholastic.com/teachers/articles/teaching-content/what-lavahttps:// https://www.bbc.com/news/magazine-29136747 https://www.amnh.org/ology/features/plates/volcanoes.php https://www.wonderopolis.org/wonder/how-is-lava-created Reference 2 how many eruptions a year? 3 On average 50-70 irruptions a year which is a very high amount of irruptions in only a 12 month time this causes a lot of damage. lava explosion sent mudflows of lava as far as the pacific ocean (120km) well it depends on what kind of lava that it is! the most hottest kinds of lava are... Felsic lava- 650°c/750°c Andestic lava-750°/ 950°c basaltic lava - 950°c braklava- 170°c if lava was to touch us at the temperature it is you would die. how hot is lava? #1 The eruption temperature of Kilauea lava is about 1,170 degrees Celsius.The temperature of the lava in the tubes is about 1,250 degrees Celsius. how hot can lavs get #2 #2 history One of the worst lava eruptions was in south America that sent mudflows as far as the pacific ocean which was 75 miles (120 km) lava is apart of the earth. no one knows when they first found lava and they might never find out 4 scientist think that they might be lava tubes on the moon which is a big discovery for everyone and could mean a lot.
