Fossil-ish
The only category of rocks that contain fossils.
What are sedimentary rocks?
They are the two types of weathering.
What are physical and chemical weathering?
It is the Rock Cycle.
What is the way rocks are formed and how they transform into other rocks?
Molten rock that is under the crust.
What is magma?
Plate boundaries where plates move apart and create new crust.
What are divergent boundaries?
That many organisms do not have structures that can be fossilized, helps to explain gaps in the fossil record.
What is yes/true?
Igneous, sedimentary, and metamorphic rocks are subjected to destructive processes to form these.
What is sediments?
Formed when molten rock cools and hardens.
What is igneous?
In seafloor spreading, the crust nearest to the mid-ocean ridge will be_____________ than the crust further away from the ridge.
What is younger?
The most common landform created at convergent boundaries.
What are mountains?
A remain or trace of a plant or animal embedded or preserved in a rock in the Earth's crust.
What is a Fossil?
The breaking apart of rocks into smaller rocks.
What is physical weathering?
This kind of rock forms when another rock is transformed from one rock to another because of heat and pressure.
What is a metamorphic rock?
The continental crust is mostly made of granite. The ocean crust is mostly made of ___________________.
What is basalt?
Ocean ridges form at this type of boundary.
What is a divergent boundary?
The law of superposition says that in an undisturbed layer of rock the older ones are on the _______________ ?
What is the bottom?
Limestone fizzing when acid is put on it is an example of this process.
What is chemical weathering?
It forms in nature, is a solid, has a definite chemical makeup, and has a crystal structure.
What is a mineral?
Rock that makes up both continental and oceanic crust.
What is silica minerals?
Volcanoes are found at which types of plate boundaries?
Major spans of time based on life-forms that have been found in rocks of that age.
What is an era?
This rock may be composed to the remains of sea creatures of from minerals precipitated from water.
What is Limestone?
Particles settle in layers that build up over time, new layers form on top of old layers, these two processes turn sediments into sedimentary rocks.
What are compacting and cementation?
Mid-ocean ridges are constantly forming new crust, this is why the Earth does not grow in size.
What is that the oceanic crust subducts under continental crust?
Trenches form this boundary.
What is a convergent boundary?
