Transcript of WEST TEXAS

research the land

israel alvarez
demonstrate plant & animal evolution of the land

During the Late Cretaceous period, limestone covered much of west Texas and had many aquifers. From the Late Cretaceous to the Early Tertiary, these rocks eventually eroded, and gave way to volcanic activity. Basin and Range structures emerged from this era and this is what exists in our present quaternary period.

Cretaceous period
quaternary period
cretaceous period
early Cretaceous --during the early cretaceous, West Texas was again covered by ocean. Ammonites and other shellfish are predominantly found amongst the sandstones and limestones deposited during this time period.
tertiary period
Quaternary Period -- Loads of sand and silt are carried from areas of high elevation to lower elevations by rainfall. Desert vegetation and sparse grasslands now cover the area. Bears, javelina, rabbits, and coyotes inhabit the region. The Potrillo volcanic field, was very active during this period and activity continued until about 40,000 years ago.
quaternary period
Tertiary- During the tertiary period, west Texas underwent a period of volcanism and erosion.
Mid Cretaceous - For most of the mid Cretaceous, West Texas was covered by ocean. Later on, the region had a swampy environment as the ocean began to move to its present location.
Late Cretaceous - The late Cretaceous was a time of uplift for the region. This caused the ocean to recede, and vast swamplands with dense vegetation. Considerable clay was deposited with it.
introduction :
We are doing west Texas because of its rich oil.
There was an erosion called the dust bowl it is like a big storm just on the ground and covers houses with so much dust. the dust bowl makes dust that looks like a bowl.it occurs after or before drought.the dust bowl causes erosion to the land.
West Texas geologic history is unique. it had a mixture of placid ocean deposition, murky swamps, and violent earth shaking volcanic eruptions. then it evolved to small hills, grasslands, prairies, and part of the land is now is now deserted.

Permian basin
The Permian basin is an oil field, located in west Texas, and some part of southwestern New Mexico. The Permian basin oil field covers an area approximately 250 miles wide and 300 miles long. The Permian basin has been one of North America’s major oil and natural gas producing regions for nearly a century. It holds 95% percent of the nations oil and gas wells.
How is the oil extracted in the Permian basin?
The process works by pumping carbon dioxide into aging oil wells to help retrieve stranded pockets of crude. The greenhouse gas stays in the ground. Oil companies have extracted oil for decades in places like the Permian Basin.
There has been a theory that they're has been earthquakes due to fracking, drilling, but people just think its natural.
Overgrazing is a major cause of erosion in west texas.
Pollution of lakes and land is also another example of how humans have impacted the land.
The Law of Superposition west Texas in a layered, depositional sequence such as a series of sedimentary beds or lava flows, the material on which any layer is deposited is older than the layer itself. the layers are successively younger, going from bottom to top. causing earthquakes and shakes & Fires
The largest earthquake in historical times in west Texas was the 1931 Valentine earthquake, it was produced by a sudden rupture.
1 earthquake in the past 7 days
2 earthquakes in the past month
3 earthquakes in the past year
