100
A hollow fossil form clearly showing the outside features of the organism.
What is a mold?
100
The age of something compared with the age of another thing.
What is relative age?
100
"Fire-made" rock formed from hot, molten rock material.
What is igneous rock?
100
The process by which rocks are changed from one type into another.
What is the rock cycle?
200
Formed or shaped within a mold.
What is a cast?
200
Rock that has been changed by heat, by pressure, or both.
What is metamorphic rock?
200
Hardened tree sap, often a source of insect fossils.
What is amber?
200
A fossil created by a print or impression.
What is an imprint?
200
Rock formed when bits or layers of rocks are cemented together.
What is sedimentary rock?
300
Molten material below Earth's surface.
What is magma?
300
Most fossils are found in this type of rock?
What is sedimentary rock?
300
True or False: A rock is always made up of just one type of mineral.
What is False?
300
This is made up of pebbles and large grains of sand cemented together.
What is conglomerate?
300
Finding fossils of evergreen leaves tells scientists this"
What is that the area was once cool?
400
When lava cools quickly it forms rocks with___________________________________.
What is small grains and fine textures?
400
Three properties used to identify minerals are:
What are hardness, streak, and luster?
400
Describe what happens when wood or bones become petrified.
What is the once living parts are filled in by minerals?
400
This part of an animal's body is least likely to become a fossil.
What is the skin?
400
How can scientists explain relative age?
What is the bottom layer of rock is the oldest, and the top is the youngest.
500
This causes metamorphic rock to become igneous.
What is melting, then cooling and hardening?
500
Describe some different ways rocks are used.
What is pieces of rock are mixed into cement, which we use to build things. Rocks are mixed in asphalt, which we use to pave roads. We use some rocks to make sculptures.
500
Why are casts of fossils sometimes displayed in museums instead of the real fossils themselves?
What is fossils are rare and therefore valuable. Some fossils are stored safely for further study. Casts can be used in exhibits to protect the fossils themselves.
500
What are three ways fossils are formed.
What is fossils are formed in sedimentary rocks when plants or animal remains are quickly buried and left undisturbed. When insects are trapped in tree sap, sometimes the sap hardens and becomes a fossil. Some animals are fossilized by being frozen in ice or buried in tar pits. Other fossils form when plants or animals decay slowly, leaving a thin film of carbon behind. Wood and bones become petrified when once-living parts are filled with minerals.
500
Are fossils of today's plants and animals being preserved?
What is while fossils of today's plants and animals can be preserved, roads, building construction, and other human activities have resulted in fewer places left undisturbed long enough for fossils to form.
