How was fertile soil formed in Hawaii?
Fertile soil in Hawaii was formed through a combination of factors including volcanic activity, weathering of volcanic rock, and the accumulation of organic matter from plant and animal decomposition. Volcanic ash and lava deposits provided mineral-rich material while the tropical climate and vegetation helped break down the rocks over time, creating nutrient-rich soil.
What is the difference between soil and volcanic soil?
Volcanic soil is formed from volcanic ash and lava, which are rich in minerals and nutrients. This makes volcanic soil fertile and ideal for agriculture. Regular soil, on the other hand, can vary greatly in composition and fertility depending on factors like weathering, organic matter content, and parent material.
Pumice obsidian and scoria are kinds of?
volcanic rocks formed from different processes. Pumice is a light and porous rock formed from foamy lava, obsidian is a dark volcanic glass formed from quickly cooled lava, and scoria is a dark, vesicular rock formed from gas-rich lava.
What are the changes extrusive volcanic features may undergo over time?
Extrusive volcanic features, such as lava flows and volcanic cones, can undergo changes over time due to weathering and erosion. Weathering breaks down the rock material, while erosion removes the material, shaping the landforms. This process can result in the gradual leveling of volcanic cones and altering the appearance of lava flows.
What is the difference between basalt and obsidian?
Basalt is a dark-colored volcanic rock formed from the rapid cooling of lava, while obsidian is a dark volcanic glass formed from the rapid cooling of lava with high silica content. Basalt has a crystalline structure, while obsidian is amorphous and often exhibits conchoidal fracturing. Basalt is typically denser and more resistant to weathering compared to obsidian.

What are volcanic mountains formed by?
Lava
Two locations in Africa where there are fertile volcanic lava soils?
Rwanda and kenya

What kind of igneous rock is formed by volcanic neck?
lava
What types of features are formed between plates?
volcanic lava
How are volcanic rocks produced?
A volcano is formed when the molten magma (lava) beneath the crust is forced to the surface. Volcanic rock is lava that has cooled.

Weathering breaks down the rock material, while erosion removes the material, shaping the landforms.

Which of these is not a form of volcanic material?
Basalt is not a form of volcanic material; it is a type of rock that is formed from solidified lava. Volcanic materials typically include lava, ash, and tephra, which are all products of volcanic eruptions.
What are formed when the lava and ash escapes at the surface?
Volcanic landforms and features.
What type of rock is formed after a volcanic explosion?
a lava rock i think
