Read the following:

The movement of tectonic plates buries a rock deep inside Earth. Intense heat and pressure change the mineral composition of the rock and transform it into Rock A. Rock A melts and comes out to the surface of Earth during a volcanic eruption. The molten rock cools rapidly to form Rock B.
A. Rock B may have fossils.
B. Rock A may have shiny, glassy surface.
C. Rock A is composed of layers of sediments.
D. Rock B has a fine grainy texture and small crystals
I think the answer is D, but i was thinking about B. Please help me im unsure

To determine the correct answer, let's analyze the given information step by step:

1. "The movement of tectonic plates buries a rock deep inside Earth."
This indicates that a rock is pushed beneath the Earth's surface due to the movement of tectonic plates.

2. "Intense heat and pressure change the mineral composition of the rock and transform it into Rock A."
As the rock gets buried deeper, it undergoes intense heat and pressure, which causes changes in its mineral composition and transforms it into Rock A.

3. "Rock A melts and comes out to the surface of Earth during a volcanic eruption."
Due to the extreme conditions during a volcanic eruption, Rock A melts and rises to the Earth's surface.

4. "The molten rock cools rapidly to form Rock B."
When the molten rock comes into contact with the cooler air or water on the surface, it cools down rapidly and solidifies, forming Rock B.

Now, let's evaluate each statement based on this information:

A. Rock B may have fossils.
Based on the given information, there is no mention of fossils related to either Rock A or Rock B. Fossils are typically found in sedimentary rocks, which are formed from the accumulation of sediments over time. Therefore, statement A is unlikely to be true.

B. Rock A may have a shiny, glassy surface.
This statement is not supported by the given information. Since Rock A forms due to the transformation of a buried rock under intense heat and pressure, it is less likely to have a shiny, glassy surface. Therefore, statement B is unlikely to be true.

C. Rock A is composed of layers of sediments.
There is no mention of Rock A being composed of layers of sediments in the given information. As mentioned earlier, Rock A is formed through the transformation of a buried rock due to heat and pressure. Therefore, statement C is unlikely to be true.

D. Rock B has a fine grainy texture and small crystals.
Based on the given information, Rock B is formed when the molten rock cools rapidly. Rapid cooling often leads to the formation of small crystals and a fine-grained texture in igneous rocks. Therefore, statement D is likely to be true.

In conclusion, based on the information provided, the correct answer is D. Rock B has a fine grainy texture and small crystals, while the other statements (A, B, and C) are not supported by the given information.

agree with D

Have doubts about rock A being glassy. More likely the molten rock that cooled rapidly.
