Slide Content

learn about volcanoes prepare for volcanic events identify the different parts of a volcano appreciate the important benefits of volcanic activity make a volcano model Volcanoes are majestic natural wonders that captivate our imagination and shape the landscapes around us. In this lesson, we will be able to

VOLCANO A

An opening in the Earth's surface. Usually found in a mountain, the opening allows gas, hot magma, and ash to escape from beneath the Earth's crust.

How are volcanoes form? Volcanoes are formed when molten rock called magma rises to the surface. The magma can come from the Earth's mantle or from subduction zones where one tectonic plate slides beneath another.

VOLCANO PARTS OF A

ASH CLOUD: CRATER: MAGMA CHAMBER: CONE: CONDUIT: SILL: LAVA: A reservoir where magma is stored beneath the volcano. Mass of tiny volcanic rock fragments, dust, and gases that are released into the air. A pipe-like structure that connects the magma chamber to the surface. The bowl-shaped depression at the top of the volcano. Steep, conical-shaped hill or mountain formed by layers of volcanic material. Molten rock that flows from a volcano during an eruption. Flat rock formation that forms when molten magma cools and solidifies in a crack or fissure.

Why do volcanoes erupt?

The Earth's crust is made up of huge slabs called plates, which fit together like a jigsaw puzzle. These plates sometimes move. The friction causes earthquakes and volcanic eruptions near the edges of the plates. The theory that explains this process is called plate

What will happen if the volcano erupts?

STAY INFORMED EMERGENCY PLAN Volcanic eruptions can be dangerous, but with proper preparation, we can stay safe. Here's how: EMERGENCY KIT EVACUATION ROUTES Pay attention to official warnings, updates, and evacuation orders from local authorities. Create a family emergency plan that includes meeting points, communication methods, and a designated emergency kit. Prepare a kit with essential items like food, water, first aid supplies, flashlights, and batteries. Familiarize yourself with evacuation routes and practice evacuation drills with your family.

5 ways volcanoes benefit Earth

1.)Hot springs and geysers associated with volcanoes can be used to generate electricity 2.)Raw materials Sulfur, copper and gold are produced from volcanic activity, Krippner said. Diamonds are also brought up to the surface from the mantle from a rare kind of magma, called kimberlite. 3.)Help cool the earth by removing heat from the interior 4)It gives us fertile soils, which are great for farming and crops.“ 5.)Volcanoes play a significant role in land formation. When a volcano erupts, it spews out lava, ash, and other volcanic materials that can accumulate over time and form new land.

TRIVIA!

Mauna Loa The biggest volcano on Earth is the Mauna Loa in Hawaii, United States at 9,170 feet meters. The Mauna Loa is an active shield volcano whose lava eruptions are silica-poor and very fluid.

It’s time to make a volcano. Are you ready?

MATERIALS Dishwashing liquid Water bottle Baking soda Food coloring Clay Vinegar

PROCEDURE Step 1:  Mix the dish soap, water, white vinegar, and food coloring and pour it into the empty soda bottle. Step 2:  Make a baking soda slurry with ½ cup baking soda and ½ cup water. Mix it thoroughly with a spoon, until it’s completely dissolved. Step 3:  Now, it’s eruption time! Quickly but carefully pour this slurry into the bottle and step back.  Now, watch the volcano erupt and spill out red lava

So , what’s going on? In a nutshell, the primary explanation to the chemical reaction you have just witnessed is that mixing vinegar, which is acid, and baking soda, which is base, results in the formation of carbon dioxide gas, forcing the contents of the bottle out of the volcano. When an acid and a base are mixed, they react to neutralize each other resulting in production of salt and in the process, produce carbon dioxide. In real volcanoes, carbon dioxide is also present when they erupt!
