Answers with explanations at the end would have made this perfect.

I too would like to know if my answers are correct. The problem? The video provides an address for the app > enter web address and there is a QR code > scan QR code > Oops, can’t scan the code because the device I’m using to look at the code is actually needed to scan the code > take screen shot of code? > still need device to scan screenshot which can’t be done at the same time. Am I missing something here? Other than this, I love your videos!!! I think you are trying to promote the app so this is maybe why the answers aren’t in the description? Which makes sense on some level but most people aren’t that invested. The app is for those who are. Instead of a QR code, a direct link to the app would be helpful or… just post the answers to the questions in the description.

1. Igneous (Intergrown Crystals) 2. Metamorphic (Banded crystals) I can see it's waves 3. Igneous (vesicular) 4. Sedimentary (Evidence of life) 5. Igneous (Glassy) 6. Sedimentary (compacted sediments) 7. Metamorphic 8. Igneous (vesicular) 9. Sedimentary (Evidence of life) 10. Igneous (intergrown) maybe?

[@bloodygamer2429]

Second is sedimentary (layers and compacted sediments)

Hi what software do you use to make these videos ? Its so simple and helpful thank you so much :)

1 igneous 2 metamorphic 3 igneous (vesicular) 4 sedimentary (organic) 5 igneous (glassy) 6 sedimentary 7 metamorphic 8 igneous (vesicular) 9 sedimentary (organic) 10 igneous Edited note: The answers are in correct order but I added the words in parentheses next to my answers because that’s how I believed I identified them.

WRONG

[@npttytwo]

is this correct or wrong

[@abdulquayumadeyinka5644]

​@@npttytwo Right, I'll say But that no_8, I'm thinking it's sedimentary(compacted, cemented sediments)

[@npttytwo]

@@abdulquayumadeyinka5644 Ok, thankyou

[@ad55318]

@@abdulquayumadeyinka5644 No, number 8 is Igneous, coz most of the sedimentary rocks are smooth and layered and WITHOUT vesicles, vesicles only form in igneous rocks while they cool off. Number 10 on the other hand, is misleading, coz I think it's a Granite but the texture and colour & distribution of crystals suggest it's a metamorphic rock.

[@rjkelling8085]

Help! I went to your link but can't find the answer key.

[@orpheus3756]

I’m having trouble identifying metamorphic rocks from others it seems. How do I know if the heterogeneity of the rock is due to intergrown crystals (so igneous), pressure-formed banded stripes (metamorphic) or if they got “glued” together (sedimentary)? :( Was having trouble with #1, #7 and #10 because I keep getting these characteristics mixed up

What type of rock is #7? The answer key no longer appears online.

[@mikesammartano]

Metamorphic! Some banding and foliated crystals (mica schist).

[@candacecowsert5407]

@@mikesammartano Awesome! Thank you so much! That’s what I thought it was but wanted to be sure. I appreciate all of your hard work! I’m a middle school science teacher and love showing your videos!

Hello! I am trying to find the answer in the APP but cant find them.

[@ClayMarion-y2p]

Where are the answers? It's not obvious on the app where to find these...

[@TimElsen]

Wonderful NGSS videos and app (great for Science Olympiad). Could you add the name of each rock to your answer key? If it's not too much trouble.
