An avalanche can be rock, dirt, or even snow that falls down a mountain slope.
Another term is landslide (landslip). A more specific term is rockslide.
It is an avalanche.
No. Intrusive rocks form when liquid magma "squirts" into the crust and hardens. Igneous rocks that form at the earth's surface are called extrusive rocks.
Intrusive igneous rocks form from cooled magma below Earth's surface.
The study of minerals is called mineralogy. The study of rocks is called petrology.
it is formed from aouther rock called schist
Rocks and soil
When rocks and earth slide down a mountain, it is called a landslide.

A Cairn.
When a very large volume of magma is erupted, the overlying rocks may collapse. The collapse produces a hole or depression at the surface called a caldera.
Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.
Large parts of Earth's continental crust is made up of metamorphic rocks. Metamorphic rocks play an important role in mountain building as they make up large portions of the mountain's crystalline core.
When studying geology it is important to learn and remember all of the terms. A volcano is a mountain built up fro hardened lava rocks and ash that erupted out of Earth.
Ultramafic rocks are of relatively small extent in the North Cascades, but are geologically significant because they are derived from the Earth's mantle.
== == An upward fold in a rock formation is called an anticline.
it is called Mt. Sean Lee Rocks
yes
Extrusive (volcanic) igneous rocks.
