activity 1 volcano concept map answer key

Mars has a long history of volcanic activity from the ancient volcanic areas of the southern highlands to the more recent major volcanoes of the Tharsis bulge. Introduce volcanoes to students by explaining the various and. This portion of the lesson is designed to promote the use of higher-order thinking skills and encourages the questioning, predicting, testing, and interpreting sequence that is important to scientific inquiry. Older flows become covered by younger flows or become more pocked with impact craters on places with a thin or non-existent atmosphere, like the moon or Mars. The materials are free and ready to be adapted by undergraduate educators across a range of courses including: general education or majors courses in Earth-focused disciplines such as geoscience or environmental science, social science, engineering, and other sciences, as well as courses for interdisciplinary programs. Four to six flows show a good example of a shield volcano, but three flows will be adequate for a simple shield volcano model.

This presentation includes colorful images and illustrations to explain how plants have adapted to living in soils with high concentrations of minerals. This one volcano would cover the entire state of Arizona! Various colors of play dough identify different eruption events. What are the two most explosiveeruption types? They may give the volcano a name if desired. A twirling mixture of very hot ash, gases, and other pyroclastic materials that are heavier than air and flow down a at high rates of speed. The more viscous and thicker the material is, the greater is its resistance to flow.

Be sure to mark the entire area of each lava flow — over previous flows and on the cardboard. They should indicate how the proposed cores and cuts will maximize the information they might gain from excavations. Lay the straw containing the core sample next to the hole from which it was taken. Afterwards, it melts and makes magma inside the magma chamber , and the pressure builds up until the magma bursts through the Earth's crust. It is smooth and ropey in appearance. When going through the list, students should note that ice is inorganic and natural.

When going through the list, students should note that salt is solid, inorganic, and natural. Make a note on the graph paper regarding the order of eruptions which color came first. Be sure to use location information, e. Use the term mantle plume in your definition. They are blocky in their appearance. Big felsic lava flows are uncommon, but have travelled as far as 15 km 9.

As lava flows, it cools and begins to harden, its ability to flow decreases and eventually stops. Math classes may try to compute the volume of the various flows. To determine the history of a feature, exposed strata are examined and core samples are extracted. Baking soda, vinegar and play dough are used to model fluid lava flows. When they are active, materials pour out of it. Mauna Kea in Hawaii is the biggest mountain on Earth.

Ask students to hypothesize how geologists investigate such hidden details. Overview The focus of this activity is on interpreting geologic history through volcano formation and excavation. Those that are now quiet called dormant inactive. This short cup is your eruption source eventual caldera and the cardboard is the original land surface. Ice is chemically homogeneous with formula H 2O and is crystalline.

Learn how to incorporate these teaching materials into your class. This includes lava, steam, gaseous compounds of sulphur, ash and broken rock pieces. Krakatoa, best known for its catastrophic eruption in 1883, is much smaller now. Show of volcanoes and lava flows from , , and perspectives. A good amount of the reading dealt with properties that make minerals useful. These plants are growing near salt water, in irrigated fields and in soils containing volcanic rock. These Science Volcanoes Worksheets are great for any classroom.

It usually erupts with thin flows of lava very quietly. Photomicrographs of snowflakes from can be used to show students that snowflakes are crystals, perfect and symmetrical, indicative of their crystalline nature. When these two plates meet, one of them usually the oceanic plate goes under the continental plate. If it is measured from its base on the floor of the sea, Mauna Kea is even taller than Mount Everest, the tallest mountain on land. To stress this last point, ask students what snowflakes look like. The materials engage students in understanding the earth system as it intertwines with key societal issues.

Therefore, in near-surface environments, the loss of gases makes magma more viscous a dome or a columnar. A lava tube forms a tunnel when the surface of the lava flow cools and hardens, while the interior keeps flowing through, draining away , leaving the interior hollow. Shield volcanoes can produce huge areas of basalt, which is usually what lava is when cooled. Dust is the smallest of the pyroclasts and is the second smallest. When the magma reaches the surface of the Earth the pressure difference between the gases in the magma and the surface pressures allows the magma to boil out.
