Clams live at the seashore. Fossils of clams were found in a rock layer directly below a rock layer that contained tree fossils. This is evidence can be used to support the idea that-
Fossils form more quickly at the seashore than in other places.
Clams and tress are always found in the same area.
The area where the fossils were found changed over time.
The layer containing the trees is older that the clam layer.
Under the ice in the artic are rocks with fossils. Some of those fossils are of plants that only grow in warm places. What does finding this fossil there tell us?
This are was not always cold.
Some plants can grow in rock.
Rock is always covered with ice.
The artic is not a very cold place.
Which of the following processes is an early step in the formation of sedimentary rock?
Weathering of existing rock
Crystallization of molten rock
Melting of rock in volcanoes
Chemical reactions that produce heat
Sedimentary rock can contain evidence of life because all of the following are properties of sedimentary rock EXCEPT-
it can be made from mud
it is created under the ocean
it is formed by melting rock
It can contain organic material.
Geologists might recognize a metamorphic rock by layers that are distorted and wavy because they were caused by -
compaction and cementation
melting and crystallization
erosion and deposition
pressure and heat
Rocks formed through the cooling and solidification of magma or lava.
sedimentary
