7
Because of this divergence, predict what will happen in the rift region in about 5 million yrs
Subduction will result in more volcanic activity.
sea will flood the lowlands when the rift reaches the ocean
The land will become flat as the crust continues to thicken
The rift basin valleys will be pushed up into a Mt. range
8
Which conclusion should the geologist based on the discovery of these fossils.
The stream will become part of the ocean in the future.
The fossils washed upstream from the ocean.
The area of the woods and stream was an ocean long ago
Animals that live in streams today lived in oceans long ago
9
A snail fossil is found in the desert, what will help determine the ancient environment?
looking@ characteristics of plant/animal fossils insame rock

12
Which statement regarding the relative ages of rocks and events is accurate?
Faults are younger than the rocks they cut through
A fold is older than the oldest rock layer it contains
Intrusive rock is older than the surrounding rock layers.
Layers that have been overturned are oldest base to surface
