Age of rock quiz (hope this helps)
1 Which of Earth's layers has the same chemical composition as the mesosphere?
asthenosphere
2 Which statement describes metamorphic rock formation? Select the correct answer.
Pressure causes rock to change.
3 How can Earth’s layers be defined? Select the two correct answers.
by their chemical compositions
by their physical properties
4 Which evidence would confirm that a given rock layer is newer than the layers around it?
It cuts through all the other layers.
5 What was Mohorovičić's observation?
Seismic waves travelled at varying speeds.
6 Which of the following are methods of relative aging of rocks? Select the three correct answers.
superposition
faunal succession
cross-cutting relationships
7 Drag each item to indicate whether it exhibits fracture or cleavage.
Fracture: (Blue crystal rock and solid rock with green color in it)
Cleavage: (clear crystal rock)
8 What should a model of the rock cycle show as the process that changes metamorphic rock to igneous rock?
melting followed by cooling
9 Use the diagram to answer the question.
(Layer G) formed first. (Layer F) formed more recently. (Fault H) was the last to form
all the questions are mixed but anonymous is 110% correct
If you don't have faunal succession, the other answer is "Original horizontality". If you're unsure, it's on slide 3 of the Age of Rock lesson.
bruh what are the answers for the quiz
Yazmyn is wrong I tried it and it does not work
anonymous is 100% correct!
Everyone's order will be different though, make sure you don't get mixed up!
mine did not have founal sucsetion
^^
quick! somebuddy help!
