Involves the movement of the weathered rock from their site of weathering.

Refers to the breakdown of rocks without the change in its composition.

Which among the following is NOT an agent of erosion?

Is the decomposition of rocks due to chemical reactions occurring between them minerals in rocks and the environment.

The following are processes that bring chemical weathering EXCEPT:

This occurs when oxygen combines with another substance like minerals in rocks, yielding compounds called oxides.

It is the mechanical and chemicalhammer that breaks down and sculpts rock.

It is the most common components of magma.

Metamorphism occurs at temperatureroughly between 200˚C and _______.

It occurs when the water or carbondioxide is added to rocks.

Magma can also be created when hot, liquid rock intrudes into the Earth’s crust. As the liquid rock solidifies, it loses this heat and transfer it to the surrounding crust.

Large volcanic forms with broad summit areas and low-sloping sides because the extuded products are mainly low viscosity basaltic lava flows.

A type of volcano that are usually only active for a short time and thenbecome dormant.

It is the process that transforms a grain of one mineral into a grain of another mineral having the same composition but different crystal structure.

Refers to the changes in shape and size of minerals without changing its identity.

Occurs when minerals become flattened or elongated without changing either the composition or crystal structure.

Metamorphism occurs at pressure of _____ kilobars.

Metamorphic or igneous rocks in contact with sedimentary layers indicate a period of uplift and erosion of previous igneous/metamorphic rocks, prior to the deposition of a younger sedimentary rock.

These are surfaces of erosion andnondeposition that separate younger rocks from older ones.

Originally-deposited horizontal layers are folded or tilted and then eroded.

The process that occurs when a rockchanges its form into a new one without undergoing melting or disintegration.

Faulting near the surface of the Earth causes rock to break into angularfragments or to powder.

The magma cools but the surrounding rock heats up.

The simplest type of folds.

Process in which rocks change in shape,size, location, tilt or break due to squeezing, stretching or shearing

States that at the time when any givenstratum was being formed, all the matter resting upon it was fluid andtherefore, at the time when the lower stratum was being formed, none of theupper strata existed.

States that if a body or discontinuity cuts across a stratum.  It must have formed after that stratum.

Originally deposited horizontal layersare folded or tilted and then eroded.

Refers to the movement of the Earth’scontinents relative to each other, appearing to “drift” across the ocean bed.

He is the Father of stratigraphy.

He proposed the continental drift theory.

What is the title of the book writtenby Alfred Wegener.

A long time ago, the continents formed a single landmass called__________.

Which of the follow is NOT an evidence of the Continental Drift Theory.

Which of the following statements aboutseafloor spreading is incorrect.

The rocks at the bottom layer are older than the top most layer.

A very large division of the geologic time equal to a billion years, ora very long period of time.

Finer subdivisions of time.

The half-life of carbon-14

It is a method of measuring the age of an event or object in years.

Age of fish

Leafless plants appeared on land for the first time.

Fish-like reptiles developed.

Mammals and primitive people crossed land bridges exposed by the sinkingwater level.

A bird-like reptile developed.

Mountain buildings which began the formation of the Alps in Europe, the Himalayas in Asia.

People developed intelligence and learned to domesticate animals andcultivate plants.

A primitive, tail less ape appeared

Flower-bearing plants evolved.

Starfish and trilobites became abundant.
