Shield volcanoes are formed by the relatively quiet outpouring of lava, which results in a broad and gently sloping shape. Volcanic blocks are typically associated with explosive eruptions that occur in stratovolcanoes, where gas pressure causes fragmented volcanic material to be ejected. As shield volcanoes tend to have less explosive eruptions, the formation of volcanic blocks on their slopes is rare.

What makes uplifted mountains fault-block mountains and hot-spot volcanoes different from other mountains?
Fault-block mountains are formed when blocks of the Earth's crust are uplifted and tilted along a fault line, creating steep mountain ranges. Hot-spot volcanoes, on the other hand, are formed by volcanic activity at a fixed hot spot in the Earth's mantle, leading to the eruption of magma and the formation of volcanic peaks. Both types of mountains have distinct formation processes that set them apart from other types of mountains, such as fold mountains or volcanic arcs.
What are large volcanic rock particles called?
Lapilli--Lapilli is pyroclastics the size of walnuts.Cinders-- Cinders are a type of pyroclastic material the size of a pea. According to the text, Earth An Introduction to Physical Geology, Cinders come in different forms when "ejected lava blobs are pulverized by the escaping gases".Blocks-- Blocks are particles larger than Lapilli's and are formed by harden lava.Bombs-- Bombs too help to produce blocks, but they are ejected as lava. They take on an streamline shape. They usually tend to fall on the slopes of a cone volcano and they can be ejected far from the volcano due to the force of escaping gasesI answered this earlier but this is a better answer ;)
Volcanoes pyroclastic material that is arranged in size from the largest to the smallest?
Volcanic pyroclastic materials are classified based on size, ranging from largest to smallest as follows: volcanic blocks (larger than 64 mm), volcanic bombs (64 mm to 2 mm), lapilli (2 mm to 64 mm), and volcanic ash (less than 2 mm). This arrangement reflects the process of explosive volcanic eruptions, where larger fragments are ejected with greater force, while finer particles are carried further by the eruption's gases. Each type of pyroclastic material contributes to the formation of different volcanic landforms and can affect the surrounding environment.
What are five examples of pyroclastic debris?
Five examples of pyroclastic debris include ash, pumice, volcanic bombs, volcanic blocks, and tephra. Ash consists of fine particles that can be carried by wind over long distances, while pumice is a light, frothy rock that can float on water. Volcanic bombs are larger, solid fragments ejected during an eruption, and volcanic blocks are hardened lava pieces. Tephra encompasses all types of volcanic debris ejected into the air during eruptions.
What is the volcanic fragments that are 2-64 mm in size?
Volcanic fragments that are 2-64 mm in size are classified as lapilli. These fragments are formed during explosive volcanic eruptions when magma is fragmented into small pieces as it is ejected into the air. Lapilli can vary in composition and shape, and are larger than volcanic ash particles but smaller than volcanic blocks.
Name four types of pyroclast?
VOLCANIC ASH, VOLCANIC CINDERS, VOLCANIC BLOCKS & VOLCANIC BOMBS.
What are volcanic blocks?
Volcanic blocks are large, solid rock fragments ejected during volcanic eruptions. These blocks can vary in size from small pieces to boulders and can be made of different types of rock depending on the composition of the volcano. They are typically formed from cooling and solidifying magma or from fragments of older rocks broken apart during an eruption.
What is the hawaiian term for lava that has a rough surface made of broken lava blocks?
Volcanic blocks
What are 4 different types of solid pyroclastics?
The 4 different types of solid pyroclastics are volcanic bombs, lapilli, volcanic ash, and volcanic blocks
What are These are larger than ash but smaller than volcanic bombs and blocks?
cinders
What kinds of rocks do volcanoes make?
The type of rocks volcanoes make is, ash, cinders, and bomb. Ash: Volcanic ash is made up of rock fragments less than 2 millimeters in diameter. Cinders: Cinders contain holes and tunnels left by escaping gases. Bomb: Large fragments are called blocks or bombs.
What term describes fragmental volcanic material?
Fragmental volcanic material is often referred to as pyroclastic or tephra, which includes ash, lapilli, and larger volcanic blocks and bombs produced during explosive volcanic eruptions.
What was the pyramid's in Egypt made of?
Large blocks of reformed volcanic rock, surfaced with marble.

How does volcanic ash in Earths atomosphere affect solar radiation?
It blocks (some of) it from reaching the surface of the Earth.
