Answer:
Paleozoic
Explanation:
The first insect fossils are dated to the Devonian, but because of the development of the genetics, the scientists have been able to trace the appearance of the first insects in the Ordovician. The insects originated from the crustaceans. Initially they were walking on land, but they hadn't developed wings. The wings came to develop in some insects in the Devonian, and since than it has gradually became one of their trademark features. It is interesting that the first insects actually appeared at the same time with the first terrestrial plants, and also that they are the first organisms to develop wings and be able to fly.
Answer and Explanation:
"Blocked opportunity" is the term that defines the state when a particular person is not able to achieve the desired goal due to the society or any other factor. The opportunity that the person is waiting for or had high hopes with goes away from the hand , this situation leaves the person in the state of sadness or depression.
This state also leads to stain the person and his thoughts. The situation of strain and delinquency sometime lead to criminal tendencies as well according to many theories. Crime causing act is performed towards the society because the person starts to blame society element behind the failure of not achieving the goal and unsuccessful.
Answer:
Cypress Hills of southwestern Saskatchewan and southeastern Alberta
the Rocky Mountains are younger than the Appalachian Mountains. The Appalachian Mountains are in the East and the Rocky Mountains are in the West. ... The Coast Ranges are low mountains near the ocean and Sierra Nevada is high and covered in snow.
Its location on the west coast of a continent in the midlatitudes places the climate in the path of the Westerlies. In this situation, the climate receives a constant influx of oceanic air throughout the year. The mild temperatures are a direct result of the moderating influence of ocean bodies on air temperatures.
Mediterranean climates cover a very restricted area of the planet's total land surface, mostly found between 30 and 45 degrees of latitude. ... Humid subtropical climates prevail over a larger area, mostly between 20 and 35 degrees of latitude but extending equatorward to about 15 degrees and poleward to about 40 degrees.
Explanation:
Answer: Adiabatic temperature gradient is the rate of change in temperature due to pressure under adiabatic conditions.
Explanation:
The rate of change of temperature due to pressure under adiabatic conditions is referred to as adiabatic temperature gradient.
In practice, since in the sea the pressure changes can be considered proportional to depth changes, the adiabatic temperature gradient is usually given as rate of change per unit depth, instead of per unit pressure and for practical purposes and calculations, the unit of depth is often chosen as 1000 m.
The natural and non-natural heat transfer influence the process of adiabatic temperature gradient.
