can someone check my answers, please and thank you?:) I know they are pretty obvious but I just want to make sure!

B. Chemical
C. Sedimentary ****
D. Igneous ****
E. Magmatic
F. Biogenous
From the web:
What's the difference between rocks and minerals?[edit] A mineral is a naturally not occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by geological processes. A rock is an aggregate of one or more minerals whereas a rock may also include organic remains and mineraloids.
So, I am going to change my answer for number 1 to B. I am keeping 2's answer however
You answered the second question correctly.
To check your answers, let's go through each question step by step.
1. How is a rock different from a mineral?
To determine the correct answer, we need to understand the definitions of both terms.
A. It is not different, they are the same things and the words "rock" and "mineral" can be used interchangeably - This answer is incorrect because rocks and minerals are not the same things.
B. A rock is made up of minerals - This answer is correct. Rocks are composed of minerals, which are naturally occurring inorganic substances with a specific chemical composition and crystal structure.
C. Minerals are made up of rock pieces - This answer is incorrect. Minerals are not made up of rock pieces. Rather, rocks are made up of minerals.
D. Minerals are man-made and rocks occur naturally - This answer is incorrect. Minerals can occur naturally, and rocks are also naturally occurring substances.
Therefore, the correct answer is B. A rock is made up of minerals.
2. What are the three main types of rocks? Select ALL that apply.
To determine the correct answers, we need to know the main types of rocks.
A. Metamorphic - This answer is correct. Metamorphic rocks are formed due to the transformation of existing rocks through heat, pressure, or chemical processes.
B. Chemical - This answer is not one of the three main types of rocks. Chemical rocks are formed primarily through chemical precipitation, but they are not considered one of the main types.
C. Sedimentary - This answer is correct. Sedimentary rocks are formed from the accumulation and lithification (compaction and cementation) of sediments over time.
D. Igneous - This answer is correct. Igneous rocks are formed from the solidification of molten material, either within the Earth's crust (intrusive) or on the surface (extrusive).
E. Magmatic - This answer is not one of the three main types of rocks. Magmatic refers to the origin of rocks from magma, which can produce both igneous and metamorphic rocks.
F. Biogenous - This answer is not one of the three main types of rocks. Biogenous rocks are formed from the accumulation of organic remains, such as shells or plant material, but they are not considered one of the main types.
Therefore, the correct answers are A. Metamorphic, C. Sedimentary, and D. Igneous.
I hope this helps you check your answers!
