Write a description of the climate in the arabian peninsula

This graph, based on the comparison of atmospheric samples contained in ice cores and more recent direct measurements, provides evidence that atmospheric CO2 has increased since the Industrial Revolution.

The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.

Scientific evidence for warming of the climate system is unequivocal.

- Intergovernmental Panel on Climate Change

The current warming trend is of particular significance because most of it is extremely likely (greater than 95 percent probability) to be the result of human activity since the mid-20th century and proceeding at a rate that is unprecedented over decades to millennia.1

Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate.

The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century.2 Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. There is no question that increased levels of greenhouse gases must cause the Earth to warm in response.

Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earth’s climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks. This ancient, or paleoclimate, evidence reveals that current warming is occurring roughly ten times faster than the average rate of ice-age-recovery warming.3

## The evidence for rapid climate change is compelling:

Global Temperature Rise :-

The planet's average surface temperature has risen about 1.62 degrees Fahrenheit (0.9 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere.4 Most of the warming occurred in the past 35 years, with the six warmest years on record taking place since 2014. Not only was 2016 the warmest year on record, but eight of the 12 months that make up the year — from January through September, with the exception of June — were the warmest on record for those respective months.

Review the worksheet below. and the interactive 3D structure model. Complete the three statements below by filling in the strata

Marina86 [1]

Answer:

1. horizontal

2. vertical

3. inclined

Explanation:

The strata are defined as the layers of various rocks. It may be sedimentary rocks, igneous rocks, etc. The orientation of the strata determines the position of the rock layers or the altitude of the rocks in the three dimensional spaces in the earth's crust.

In the context,

The outcrop pattern of the horizontal strata are cut by the stream canyons that are parallel to the canyon walls. And the outcrop pattern of the vertical strata are cut by the stream canyon that makes an apparent straight line that crosses the canyon.

While the pattern of the inclined strata that are cut by the stream canyon which makes the apparent V shape and is pointing in dip direction.

This is because as per the rules of the V's, the inclined beds or the dipping are incised with the streams or valleys or canyons, it makes a "V" in dip direction. But when the strata have a vertical dip, then it does not make a "V". And when the beds are horizontal, it will be parallel and will follow the contours.
