D. Iowa
The corn belt covers Western Indiana, Illinois, Iowa, Eastern Nebraska, and Eastern Kansas. In these states, corn is one of the dominant crops.
Answer:
Human activity - Produces greenhouse gasses.
Greenhouse gasses - Cause atmosphere to trap more heat.
Sun's output - Can vary.
Ice age - Peaked 20,000 years ago.
Explanation:
Human activity includes the usage of fossil fuels on a very large scale, and by using them we release huge amounts of greenhouse gasses into the atmosphere.
The greenhouse gasses have the ability to trap the heat that is reflected from the surface of the planet, thus keeping more of it in the atmosphere and causing global temperature rise.
The sun is technically a star, thus an object that produces energy and light, and like every star, it has variations in its activity in accordance with the processes going on on it.
There have been numerous ice ages through the geological past, and the last one of them ended only around 10,000 years ago, with its peak being just 20,000 years ago.
Answer:
A. Geology
B. Computer aided designs
C. Dead organisms in the oceans
D. Helps in converting dead organisms into oil and gas
Explanation:
The oil and natural gas are buried under layers and this requires a good knowledge of "geology". Furthermore, equipments must be built to explore this oil and natural gas
Involvement of Technology has to do with "Computer aided models" being generated. Seismic surveys and satellites used to collect data.
Oil and gas began as dead plants and animals living in the ocean millions of years ago.
Role of sedimentation: the Organisms in the ocean died and went to the bottom of the ocean, where a layer of sediment would cover them. Over the years, alternating layers of dead organisms and sediments were formed. As the layers bottled up, the immense pressure and heat converted the dead organisms into oil and natural gas.
The correct answer is - In most Latin American countries, the majority of locals speak Spanish.
Most of the countries in South America have Spanish as their official language, but it is not just the language that is a trait that connects people, it is also the influence of the Spanish culture as well, even in the few countries where it is not a dominant language.
