Blocky lava, also known as aa lava, is characterized by its rough, jagged surface and indicates a higher viscosity in the magma. This increased viscosity can trap gases, leading to greater pressure buildup within the volcano. When the pressure is eventually released, it can result in explosive eruptions. Therefore, the presence of blocky lava suggests a greater potential for explosive volcanic activity compared to more fluid lava types.

Why is blocky lava an important clue to the explosiveness of volcano?

Blocky lava, known as andesitic or rhyolitic lava, typically indicates a high-viscosity magma that traps gases, leading to explosive eruptions. The angular, jagged formations of blocky lava suggest that the lava cools and solidifies relatively quickly, often in a more viscous state. This behavior contrasts with fluid basaltic lava, which tends to flow smoothly and produce less explosive eruptions. Therefore, the presence of blocky lava can signal a volcano's potential for more violent eruptive activity.


Why is a volcano an opening in the earth's crust?

A volcano is an opening in the earth's crust because it allows magma from beneath the surface to reach the surface, causing volcanic eruptions. Magma is molten rock located beneath the Earth's surface, and when it erupts through a volcano, it can create new landforms and release gases and ash.

One important clue is the Doppler effect - the redshift of distant galaxies. It turns out that the greater the distance to a galaxy, the faster it moves away from us.One important clue is the Doppler effect - the redshift of distant galaxies.

How to use betamax through magnetism?

To use betamax through magnetism, you would need a betamax tape and a suitable magnetic playback device such as a betamax VCR. Insert the tape into the VCR, ensuring it is wound properly. The magnetic heads in the VCR will read the magnetic signals recorded on the tape to play back the audio and video content.
