The major fire occurred in the Chicago in 1871 because of persistent high-pressure zones that prevented moisture-laden winds from the Gulf of Mexico reaching the area.

The Great Chicago Fire was a blaze that raged in Chicago, Illinois, in the United States, between October 8 and 10, 1871. Over 17,000 buildings and about 3.3 square miles (9 km2) of the city were destroyed by the fire, which also left about 300 people dead and more than 100,000 people homeless. [3] Southwest of the city's center, a neighborhood caught fire. The city's predominately wooden construction, coupled with a protracted period of hot, dry weather, contributed to the fire. The fire first jumped the Chicago River's south branch, destroying much of central Chicago, before jumping the river's main branch and destroying the Near North Side.

Option (c ) ridges subduction and (d) trench rifts are the correct options.

Therefore, ridges and rifts are associated with a divergent boundary.

What is a Divergent Boundary? It is an area where two tectonic plates are separating or two crustal plates are moving apart from one another. It is also known as divergent plate boundary, or extensional boundary or constructive boundary. When two plates move away from each other they create a gap or a crack. This crack can be filled by the magma from beneath the surface of earth. There are mainly two kinds of plates involved in this procedure: the oceanic and the continental plates. Most of these divergent boundaries occur between two oceanic plates. Example: Mid-Atlantic range.

If a large airport, complete with paved runways, parking lots, and many new structures, is built next to a river, what might the effect be?

Answers

If a large airport, complete with paved runways, parking lots, and many new structures, is built next to a river, it may be an increase in the likelihood of flooding

Flooding, the most common sort of natural disaster, happen when an excess of water submerges normally dry ground. Flooding are frequently brought on by prolonged periods of heavy rain, quick snowmelt, or storm surges from tropical cyclones or tsunamis in coastal locations.

Overflowing rivers and streams are the most typical. Riverine floods are the name for these flooding. A river can become overwhelmed and spread over the neighboring area due to heavy rain, a broken dam or levee, rapid ice melt in the mountains, or even a beaver dam in a vulnerable location. The volume of water and sediment that flow through a river channel naturally shapes it.

Answers

The age of the oldest sediments recovered by deep-ocean drilling is 180 million years old in the ocean 4 billion years old on the continent.

What are sediments?Sediment is a naturally occurring substance that is broken down by weathering and erosion processes and then moved by the force of gravity acting on the particles or by the action of wind, water, or ice.For instance, sand and silt may be conveyed in river water in suspension and deposited on the sea floor by sedimentation; if buried, they may eventually undergo lithification to create sandstone and siltstone, respectively. Although wind, glaciers, and water are the most common means of movement for sediments.

Deposition are exemplified by beach sands and river channel deposits, but sediment also frequently settles out of still or slowly flowing water in lakes and seas. Aeolian transport and deposition are demonstrated by desert sand dunes.

Answers

Urban heat islands can negatively impact urban communities as temperatures increase from climate change option b) Increase impervious surface.

Heat islands make contributions to higher daytime temperatures, reduced middle-of-the-night cooling, and higher air-pollution levels. these, in turn, contribute to warmness-related deaths and heat-related illnesses such as fashionable discomfort, respiratory difficulties, warmness cramps, heat exhaustion, and non-deadly warmth stroke.

Scientists say the “urban warmness island” effect, which could improve temperatures in towns by numerous degrees in comparison with their environment, will be a threat to human health as growing urban populations exacerbate the heating results of weather change.

These heat islands form due to the fact urban surfaces which include roadways and rooftops absorb and emit heat to a greater extent than most natural surfaces.
