Which of the following rocks would most likely be found near a volcano?
marble

What rocks would most likely be found near a volcano?
When lava reaches the surface of the Earth through volcanoes or through great fissures the rocks that are formed from the lava cooling and hardening are called
extrusive igneous rocks
. Some of the more common types of extrusive igneous rocks are lava rocks, cinders, pumice, obsidian, and volcanic ash and dust.
What would most likely be found near a volcano?
If you walk around a volcano, you will find those extrusive types. The intrusive types are usually found in areas called
plutons and dikes
, big old pools of molten rock that were just beneath the surface. Some examples of igneous rock are granite, all volcanic rock, basalt, and obsidian.
Why igneous rocks are found in the regions of volcanoes?
Answer:
Magma is less dense than the surrounding rock which causes it to rise
. When magma reaches the surface it is then called lava and the eruptions of lava and ash produce volcanoes. The lava that reaches the Earth’s surface will harden and become igneous rock. …
Which of the following rocks would you most likely find in a cave?
The correct answer is
chemical sedimentary rock
This is a kind of sedimentary rock which is most likely to be formed in a cave.
Why do some rocks have lines in them?
Striped patterns in stones are usually
caused by layers of sediment that have accumulated over time
. … Much of Earth’s history is recorded in layer upon layer of sediment. This is one of the fundamental concepts of geology. When a layered rock is quarried and sawn into blocks, its layers look like stripes.
What is volcanic rock called?
Extrusive, or volcanic,
igneous rock
is produced when magma exits and cools above (or very near) the Earth’s surface. These are the rocks that form at erupting volcanoes and oozing fissures.
In which location would you most likely find volcanoes quizlet?
In which location would you most likely find volcanoes?
Along mid-ocean ridges and where a plate is subducted
. You just studied 27 terms!
Where would an explosive volcano most likely occur quizlet?
Where do most volcanoes occur on Earth’s surface? Most volcanoes occur
along diverging plate boundaries
, such as the mid-ocean ridge, or in subduction zones around the edges of oceans.
Where are volcanoes most likely to form quizlet?
Volcanoes are most likely to form
near tectonic plate boundaries
.
What is intrusive igneous rocks?
Intrusive Igneous Rock
Intrusive, or plutonic,
igneous rock forms when magma remains inside the Earth’s crust where it cools and solidifies in chambers within pre-existing rock
. The magma cools very slowly over many thousands or millions of years until is solidifies.
What type of rock are fossils found in?
Fossils are typically found in
sedimentary rocks
and occasionally some fine-grained, low-grade metamorphic rocks. Sometimes the fossils have been removed, leaving moulds in the surrounding rock, or the moulds may have later been filled by other materials, forming casts of the original fossils.
What is an active volcano called?
An active volcano is a
volcano that has had at least one eruption during the past 10,000 years
. … An erupting volcano is an active volcano that is having an eruption… A dormant volcano is an active volcano that is not erupting, but supposed to erupt again.
Which tests can help identify a mineral?
- Hardness. The ability to resist being scratched—or hardness—is one of the most useful properties for identifying minerals. …
- Luster. Luster is how a mineral reflects light. …
- Color. One of the most obvious properties of a mineral is color. …
- Streak. …
- Specific Gravity.
Which sedimentary rock type would you most likely find as stalactite in a cave?
Limestone
. The most common rock in Mammoth Cave is limestone. Limestone is a sedimentary rock that allows cave passages to easily form because of its chemical makeup and ability to be dissolved by acidic groundwater.
What does a line of rocks mean?
Generally, rock cairns are
a way of marking the right way on not-so-well-defined trail
. … If you head farther North to Acadia National Park in Maine, you’ll find stacked rocks, known as “cairns” marking most paths.
