• absolute dating

• relative dating

• tinder dating

• blind dating

An intrusion is always younger than the layers that it crosses because...?

• The layers that the intrusion cuts across must have been deposited before the intrusion occurred. Otherwise, the intrusion would not have a rock layer to intrude through.

• The layers that the intrusion cuts across must have been deposited after the intrusion occurred. Otherwise, the intrusion would not have a rock layer to intrude through.

• Intrusions move from top to bottom cutting across older rock layers first.

• Intrusions move from bottom to top cutting across younger rock layers first.
