What is a rock consisting of angular fragments embedded in finer matrix formed by volcanic activity?
A rock consisting of angular fragments embedded in a finer matrix formed by volcanic activity is called a volcanic breccia. This type of rock is created when fragments of volcanic material are ejected during an explosion, then subsequently lithified into a solid rock.
What type of rock is tuff?
Tuff is a type of volcanic rock formed from volcanic ash and debris that has been compressed and cemented together. It has a light and porous texture due to the presence of air pockets and is commonly found in areas with volcanic activity.
Many of the Caribbean islands were formed by what type of tectonic activity?
Many of the Caribbean islands were formed by volcanic activity along tectonic plate boundaries, particularly where the North American Plate and the Caribbean Plate interact. This activity has led to the creation of volcanic islands and underwater mountain chains in the region.
Which type of ultrabasic rock sometimes contains diamonds?
Kimberlite is a type of ultrabasic rock that sometimes contains diamonds. These rocks are formed deep within the Earth's mantle and are brought to the surface through volcanic activity, carrying diamonds with them.
What type of rock is a pumice rock?
Pumice is a type of igneous rock formed from volcanic eruptions. It is characterized by its porous and lightweight nature, caused by the rapid cooling of lava during volcanic explosions, which traps gas bubbles in the rock.

How does volcanic activity affect the formation of volcanic rock?
Volcanic activity heats up and melts existing rock beneath the Earth's surface, creating molten magma. This magma is then forced to the surface through volcanic eruptions, cooling and solidifying to form volcanic rocks such as basalt, andesite, or rhyolite. The specific composition and characteristics of the volcanic rock depend on factors like the type of magma, eruption style, and cooling rate.
What type of rock is formed after a volcanic explosion?
a lava rock i think
What type of rock is on Mt Snowdon?
The rock on Mount Snowdon is predominantly volcanic in origin, consisting of rhyolite and tuff formations that were formed during a period of intense volcanic activity around 450 million years ago.
How was hanging rock Victoria formed?
Hanging Rock in Victoria was formed through volcanic activity millions of years ago. It is composed of a type of volcanic rock called diabase, which was pushed up from deep within the Earth's crust and hardened over time. Wind and water erosion then shaped the rock into its current form.
What type of rock can be formed when volcanic rock is altered by heat and pressure?
Metamorphic rock, such as schist or gneiss, can be formed when volcanic rock is altered by heat and pressure. This process can cause the mineral composition and texture of the rock to change, resulting in a new type of rock with different features than the original volcanic rock.
What type of rock does volcanic activity produce?
Extrusive igneous rock is produced by the solidification of lava.
What does magma composition play a major role in?
The type of rock formed when the magma cools. The type of volcano or volcanic intrusion that is formed The explosiveness of volcanic eruptions.
What kind of rock makes up Hawaiian Islands?
The Hawaiian Islands are primarily composed of basaltic rock, which is a type of volcanic rock formed from the solidification of lava flows. This type of rock is rich in iron and magnesium and is commonly associated with volcanic activity.
Is volcanic rock the same as Metamorphic rock?
No. Volcanic rock (or igneous rock) is formed when lava cools. A metamorphic rock is formed when a rock changes because of tremendous heat and pressure underneath the earth to become a new type of rock.
Is gabbro a moon rock?
Yes, gabbro is a type of rock that can be found on the Moon. Gabbro is a common type of igneous rock formed from the cooling of magma. It is likely present in the lunar crust due to past volcanic activity on the Moon.
