10 Questions
According to the law of original horizontality, what happened first in the formation of rock layers?
Layers laid down in a horizontal pattern
Which rock layer would be the youngest according to the law of superposition?
Layer 7
What geological event occurred first in the landform diagram?
Deposition of layers 1-4
Why are layers 6 and 7 considered the youngest in the landform diagram?
They follow an unconformity
What caused the folding and bending of rock layers according to the text?
Forces in the earth
In what manner did magma seep through the rock layers in the landform diagram?
Diagonally
Which event marked the end of the formation of layers 6 and 7 in the landform diagram?
Deposition of layers 1-4
'The tube of magma does not continue past the unconformity' - Why is this significant based on the information provided?
'It shows a gap in geological history.'
'Layers laid down in a horizontal pattern' - What does this imply about rock formation according to the law of original horizontality?
'Rock layers formed parallel to Earth's surface.'
'Magma seeped through them' - Why is this statement important in understanding the sequence of events in the landform diagram?
'It marks the end of layer deposition.'
Test your knowledge about how geologists study the earth's past through landform diagrams and the principle of uniformitarianism. Learn about the methods used to make assumptions about past geological events and the importance of natural laws in understanding earth's history.
