What is mummification?

Back

Mummification is the process of preserving a body in very dry places, preventing decay and allowing for fossil formation.

Front

What type of sedimentary rock is formed from minerals that were once dissolved in water?

Back

Chemical sedimentary rock is formed from minerals that were once dissolved in water.

Front

What does MA stand for in geological time?

Back

MA stands for 'million years ago', a unit used to denote time in geology.

Front

What is quartzite?

Back

Quartzite is a non-foliated metamorphic rock formed from the metamorphism of sandstone.

Front

What is a varve?

Back

A varve is a pair of sedimentary layers that represent one year of deposition, often found in glacial lakes.

Front

What is petrification?

Back

Petrification is the process by which organic material becomes fossilized through the replacement of its original material with minerals.

Front

What is sedimentation?

Back

Sedimentation is the process by which particles settle out of a fluid, forming layers of sediment.

Front

What is the difference between clastic and chemical sedimentary rocks?

Back

Clastic sedimentary rocks are formed from fragments of other rocks, while chemical sedimentary rocks form from minerals precipitated from solution.

Front

What is the Pliocene Epoch?

Back

The Pliocene Epoch is a period in geological time that began about 5.3 million years ago, characterized by significant geological and climatic changes.

Front

What is the significance of tree rings in geology?

Back

Tree rings can provide information about past climate conditions and are used in dendrochronology to date events.
