A student researches how two types of rocks are formed and records the information below.
Rock Formation
Rock 1: Formed by cooling magma
Rock 2: Formed by compacting and cementing particles together
The student claims that Rock 2 is more likely to contain a fossil than is Rock 1. Which statement BEST describes the student’s claim?
Answer it for me please
Naomi for mr.Smith class is cheating Imma tell mr.smith hahahahaha REVENGE!!!
A student observes the rock shown.
What question can the student ask to help describe the rock's luster?
A.
Is the rock hard?
B.
Is the rock shiny?
C.
Is the rock smooth?
D.
Is the rock dark in color?
The student’s claim suggests that Rock 2 is more likely to contain a fossil compared to Rock 1. To understand the reason behind this claim, it is important to consider the formation processes of both rocks.
According to the information provided, Rock 1 is formed by cooling magma. This type of rock is called an igneous rock. When magma cools and solidifies, it forms crystals, and the rapid cooling typically prevents the preservation of fossils. Therefore, it is less likely for Rock 1 to contain fossils.
On the other hand, Rock 2 is formed by compacting and cementing particles together. This type of rock is called a sedimentary rock. Sedimentary rocks often form from the accumulation of sediment, such as sand, mud, or organic material. These sediments can include the remains of plants or animals, which have the potential to become fossils. Therefore, it is more likely for Rock 2 to contain fossils compared to Rock 1.
Based on this information, the student’s claim that Rock 2 is more likely to contain a fossil than Rock 1 is supported by the processes of rock formation.
