___________ rock is formed when magma cools
Explanation
Igneous rock is formed when magma, which is molten rock beneath the Earth's surface, cools and solidifies. This process can occur either underground or on the Earth's surface. As the magma cools, it crystallizes and forms igneous rock. This type of rock is characterized by its interlocking crystals and can have a variety of textures and compositions depending on the cooling rate and mineral content of the magma. Examples of igneous rocks include granite, basalt, and obsidian.Rate this question:

- 4.
A rock has fossils in it. It is a _______ sedimentary rock.
-
Intrusive
-
Chemical
-
Organic
-
Foliated
Correct Answer
A. OrganicExplanation
The presence of fossils in the rock suggests that it is an organic sedimentary rock. Organic sedimentary rocks are formed from the accumulation and lithification of organic remains, such as plants or animals. Fossils are the preserved remains or traces of ancient organisms, so their presence in the rock indicates that it was formed from the accumulation and compaction of organic material over time.Rate this question:

A volcano erupts and then cools. Then that rock weathers down and compacts. Put into order the steps this rock went through in the rock cycle.
-
Pyroclastic, ah ah
-
Sedimentary, metamorphic
-
Igneous, metamorphic
-
Sedimentary, igneous
-
Igneous, sedimentary
Correct Answer
A. Igneous, sedimentaryExplanation
The rock cycle is a continuous process that involves the formation, weathering, and transformation of rocks. In this case, the rock started as igneous rock when the volcano erupted and cooled. Over time, this igneous rock weathered down into smaller particles and eventually compacted, forming sedimentary rock. Therefore, the correct order of steps the rock went through in the rock cycle is igneous, sedimentary.Rate this question:

Which of the folowing BEST describes how rocks change to medamorphic?
-
Heat and pressure
-
Erosion
-
Magma cooling
-
Intense heat and pressure
-
Pressure
Correct Answer
A. Intense heat and pressureExplanation
If you chose a, it is incorrect because you need to have higher than normal heat and pressure for rock to become metamorphic.Rate this question:

A medamorphic rock is foliated when
-
It has large crystals.
-
It's grains are alined in rows.
-
It's grains are not alined in rows.
-
Rock fragments are squeezed together.
Correct Answer
A. It's grains are alined in rows.Explanation
A metamorphic rock is foliated when its grains are aligned in rows. Foliation refers to the parallel arrangement of mineral grains or structural features within a rock. This alignment occurs due to the pressure and heat experienced during the rock's formation. The alignment of grains in rows creates a layered or banded appearance in the rock, which is characteristic of foliated metamorphic rocks.Rate this question:

_______ are natural, solid substances formed in earths crust. They are made of one or more minerals.
Correct Answer
Rocks

Rocks are natural, solid substances formed in the earth's crust. They are made up of one or more minerals.Rate this question:

You see an igneous rock that has large crystals and is rough, what type of igneous rock is it?
-
Non-foliated
-
Intrusive
-
Extrusive
-
Chemical
Correct Answer
A. IntrusiveExplanation
The given correct answer is intrusive. Intrusive igneous rocks are formed when magma cools and solidifies beneath the Earth's surface. These rocks have large crystals because the slow cooling process allows enough time for the crystals to grow. The rough texture is a result of the interlocking arrangement of the large crystals.Rate this question:

Which of the following rock types can transform directly into another rock type through the process of lithification?
-
Igneous to Metamorphic
-
Sedimentary to Igneous
-
Metamorphic to Sedimentary
-
Sedimentary to Metamorphic
Correct Answer
A. Metamorphic to SedimentaryExplanation
Lithification is the process where sediments compact and cement together to form sedimentary rocks. A metamorphic rock can weather and erode into sediments, which then undergo lithification to become sedimentary rock. The direct transformation of metamorphic to sedimentary through lithification is a more complex concept, making this question challenging. Other transformations mentioned involve different processes, such as heat and pressure for metamorphism or melting and cooling for igneous rock formation.Rate this question:
