How many seismometers are needed to determine the location of an epicenter of an earthquake?

Answers

Answer 1

Answer:

Explanation:

Three seismographs

Three seismographs are needed. A circle is drawn from each of the three different seismograph locations, where the radius of each circle is equal to the distance from that station to the epicenter. The spot where those three circles intersect is the epicenter (Figure 13.12).

Deserts can be found near oceans on the coast of continents?.

Answers

Answer:

Yes.

Explanation:

Coastal deserts, as the name indicates, are deserts that stretch along the shore. They're one of the four primary desert varieties. Their proximity to the sea endows them with distinct characteristics not present in other deserts. Deserts like this are common on the western margins of continents, when cold ocean currents flow parallel to the shore. The air above is unable to contain moisture due to the cold currents, and the majority of it falls as rain on the sea before reaching land. As a result of the cold ocean currents, the area around the shore receives little or no precipitation and becomes a desert. Winters in coastal deserts are generally brief, with temperatures of 5°C and lower, with the lowest temperature recorded being -4°C. Summer temperatures in the coastal deserts range from 13°C to 24°C, with 35°C being the maximum ever recorded. Every year, an average of 13cm of rain is recorded. Despite their proximity to water sources, these deserts remain noticeably dry because the majority of precipitation falls in the ocean, with just a little portion reaching land. The soils in these deserts are more permeable, with a moderate texture and salt concentration. The production of strong fogs in the winter is another distinctive feature of coastal deserts. Upwelling cold currents cause such fogs to develop, which coat the desert and prevent sun rays from reaching the sands.

how one's political beliefs can be shaped by where they live

Answers

Answer:

I would say that the answer is the third option: "how one's culture is often determined by where they live on Earth".

Explanation:

Culture encompasses many aspects of one's life including their language, traditions, beliefs, and even what they eat and wear. Since living in a rocky terrain will result in the masses of people having a diet consisting of grapes and olives, they'll naturally pass down whatever recipes they've accumulated, from generation to generation.

Compare and contrast the effects of warm and cold currents on climate

Answers

Answer:

The cold currents often form when the air on the subtropical high blows over a cold mass of water, then the cold air is dragged to the equator. Warm currents, on the other hand, are large masses of warm water moving further away from the equator, at higher temperatures.

Cold ocean currents move towards the equator which forms cold air and Warm currents, on the other hand, move away from the equator resulting in formation of hot or warm air.

How do warm and cold currents affect the climate?

The ocean currents act as thermal condensers, transmitting heat to tropical areas and helping tropical areas cool down, thus affecting both the weather and the climate.

Cold waves often form when hot air blows over cold water, and cold air is drawn into the equator.

Warm currents, on the other hand, are the warmest waters of the equator, at higher temperatures.

Thus, Cold ocean currents move towards the equator which forms cold air and Warm currents, on the other hand, move away from the equator resulting in formation of hot or warm air.

What do the atmospheres of venus and mars teach us about our own atmosphere

Answers

Earth’s atmosphere is a mixture of nitrogen (79%), oxygen (20%), and a small fraction of carbon dioxide, water vapours and other gases. This makes the existence of life possible on Earth. However, the atmospheres on Venus and Mars mainly consist of carbon dioxide. The amount of carbon dioxide on these planets can range from 95% to 97%. This may be the reason no life exists on these planets.

The atmosphere of Venus is about 96 per cent carbon dioxide, with surface temperatures around 737 K (464 °C, or 867 °F).
Venus itself rotates only once every 243 Earth days.
Mars, in contrast, has a thin atmosphere composed of about 95 per cent carbon dioxide, with the remainder being mostly diatomic nitrogen.
