Question

a geologist finds a rock with large visible crystals that formed deep underground from slowly cooling magma.

  1. what type of rock is this?

a) igneous
b) sedimentary
c) metamorphic.

  1. is this rock:

a) extrusive
b) intrusive.
during a volcanic eruption, lava cools quickly on the surface, forming a dark, fine - grained rock.

  1. what type of rock is this?

a) igneous
b) sedimentary
c) metamorphic

  1. is this rock:

a) extrusive
b) intrusive.
layers of sand and clay are compacted and cemented over millions of years at the bottom of a riverbed, forming a rock.

  1. what type of rock is this?

a) igneous
b) sedimentary
c) metamorphic

  1. which process is primarily responsible for forming this rock?

a) heat and pressure
b) deposition, compaction, and cementation
c) cooling of magma.
a mountain range is formed where tectonic plates collide, exposing rocks to high pressure and temperature over a large area, creating a banded rock.

  1. what type of rock is this?

a) igneous

Explanation:

Question 1
Brief Explanations

Las rocas ígneas se forman a partir del enfriamiento del magma. Las rocas formadas por magma que se enfría lentamente bajo la superficie tienen cristales grandes. Entonces, esta roca es ígnea.

Brief Explanations

Las rocas ígneas intrusivas se forman cuando el magma se enfría lentamente bajo la superficie de la Tierra, lo que permite que se formen cristales grandes. Dado que la roca del problema 1 se formó a partir de magma que se enfrió lentamente bajo tierra, es intrusiva.

Brief Explanations

Las rocas ígneas se forman por el enfriamiento del lava (o magma). Aquí, la lava se enfría rápidamente en la superficie durante una erupción volcánica, formando una roca ígnea.

Answer:

a) Igneous
