Wind carrying sand grains deposits the sand when the wind

Wind carrying sand grains deposits the sand when the wind slows down or hits an obstacle.

What are some jobs that have to do with weather

Weatherman and scientist (The kind of scientist who studies weather).

Wegener's continental drift hypothesis stated that all the continents once joined together to form

the supercontinent pangaea

Which type of air mass originates in northern Canada

cT

What force causes most of the erosion in desert areas

Running Water

What is the differences of epoch and era

Both epochs and eras are divisions of geological time

The largest of the time divisions are Super-Eons.

Super-Eons are sub divided into Eons.

Eons are sub divided into Eras.

Eras are sub divided into Periods

Periods are sub divided into Epochs

Epochs are sub divided into Ages.

Used to date fossils in rocks to give an approximate age

Radiocarbon Dating.

Radiometric dating does not usually work with sedimentary rocks because they

Form from many older rock particles.

What defines atmosphere

Atmosphere is the transparent gaseous envelope that surrounds the earth. Other than earth there are two more planets that possess atmosphere Venus and Mars.

Geologists have divided earths history in the manaeable units that are represented by the

Geologic time scale

An air mass is a large body of air with uniform temperature and

temperature humidity and pressure

Which type of geologic event has to occur to create an angular unconformity

The folding or tilting of rocks, followed by renewed deposition, has to occur to create an angular unconformity.

What is measured in the radiocarbon dating of organic materials

Carbon 14 is the isotope of carbon measured in radiocarbon dating.

What are long sand ridges oriented nearly parallel to the prevailing wind called

longitudinal dunes

What is problematic about the potassium argon method of radiometric dating

Argon is a gas that may leak from a sample and provide inaccurate data

What kind of weather does a continental tropical air mass bring

Hot and sunny. ;)

What does the radiometric date of metamorphic rock most likely represent

heated during metamorphism

Which item could be dated using radiocarbon dating

A 60,000 year old mammoth bone.

The boundaries of history of eras are marked by great worldwide changes in

The boundaries of history of eras are marked by great worldwide changes in continental coastline

When wind creates a sand dune what is the the sheltered side of the dune

The side downwind of the prevailing wind direction.
