Sedimentary rock transforms to igneous rock by ...
melting and cooling
its not possible
evaporation and condensation

5
Volcanoes and earthquakes often happen in the same places because,
they are natural disasters.
they are both caused by plate movement.
we can predict volcanic eruptions better than we can predict earthquakes.
both can cause a lot of destruction.

To improve humans health?
To make predictions about the weather.
To learn about ancient life and Earth's history.
To learn about governments around the world.
7
What is the main purpose of the geologic time scale?
to organize the Earth's history
to help people understand that the Earth is very old
to learn about organisms
to compare very short and very long periods of time
8

body fossils
trace fossils
carbon film fossils
9
Underwater earthquakes can be dangerous to people living near the ocean because they can cause
tsunamis.
oceans to have a lot of wind.
ash to block out the sun.
sea animals to be more agressive towards people.

False
True
15
What is the 'geologic time scale'?
a timeline of Earth's long history.
age of a rock or fossil in years
a cylinder-shaped sample of ice drilled
the age of an object
16
After transforming into sediment, the metamorphic rock transforms to sedimentary rock by ...
heat and pressure
it has to be igneous first
cementation and compaction
