100 Facts Volcanoes – Bitesized Facts & Awesome Images to Support KS2 Learning

Product Information

These individual eruption centres are all linked to the same magma chamber, and so may be considered as one single volcano by some people. Shield-volcano Mauna Kea viewed from the northern slope of Mauna Loa (cinder cones in the foreground) shows off its broad shield shape. The denser oceanic plate is forced under the lighter continental plate and this friction causes the oceanic plate to melt. This labelling activity will help children to reinforce their knowledge of the different parts of the volcano, such as the ash cloud and lava flume.

They help children understand how volcanoes erupt in real time and the ongoing effects eruptions can have on landscapes and communities. Examples of these kinds of volcanoes include Mount Vesuvius, which erupted in 79AD and destroyed several settlements including Pompeii, and Mount St. Here, steam rises from fumaroles on the caldera floor of Pinatubo, after the June 15 eruption and caldera collapse, as viewed from the north on Oct. Active” means there’s regular activity, “ dormant” means there’s been recent activity but the volcano is currently quiet, and “ extinct” means it’s been so long since the last eruption that it’s unlikely to ever erupt again.

The molten rock is made of the chemicals oxygen, silicon, aluminum, iron, magnesium, calcium, sodium, potassium, titanium, and manganese. As late as 1768, the first edition of the Encyclopædia Britannica gave voice to a common misconception by defining volcanoes as “burning mountains, which probably are made up of sulphur and some other matter proper to ferment with it, and take fire. These geographical wonders come in various shapes and sizes, but there are two main types – composite volcanoes, which are cone-shaped with steep slopes, and shield volcanoes, which are wide with gentle slopes. One feared phenomenon accompanying some explosive eruptions is the nuée ardente, or pyroclastic flow, a fluidized mixture of hot gas and incandescent particles that sweeps down a volcano’s flanks, incinerating everything in its path. Each book is filled with a rich visual display, from jaw-dropping photographs and labelled diagrams to cutaways and detailed illustrations, to reinforce and strengthen a child’s understanding of new or complex ideas.Shield volcanoes build up slowly by the growth of thousands of lava flows that spread widely over great distances, and then cool as thin sheets. The plates always move very slowly but when the plates move suddenly they often cause an earthquake. In other cases, entrapped gases tear the magma into shreds and hurl viscous clots of lava into the air. Sideways directed volcanic explosions, known as lateral blasts, can shoot large pieces of rock at very high speeds for several miles. We aim to empower and inspire our readers with the tools needed to understand the world and appreciate its everyday awe.
