Answers

Answer 1

Seismologists studying the earthquake that struck northern California in October 1989 are still investigating some of its mysteries: the unexpected power of the seismic waves, the upward thrust that threw one man straight into the air, and the strange electromagnetic signals detected hours before the temblor.

A seismologist is an expert in seismology, or the study of earthquakes. Both words are rooted in the Greek seismos, or "a shaking," and seismologists study the factors that lead to the extreme shaking caused by quakes. These scientists also investigate related events, like volcanic eruptions, connected with movements of the earth's crust and shifting tectonic plates, and predict when and where future earthquakes will occur.

What is one way in which an ecosystem can affect a culture?
OA. Earthquakes cause rocks to move and open up new areas for
nesting.
B. Cold waters increase the amount of dissolved oxygen.
C. Plants and animals will affect how people can produce or gather
food.
D. People singing can lead to more singing and a language that uses
tones for meaning.

Answers

One way in which an ecosystem can affect culture is through the availability and diversity of plants and animals, which directly influence how people can produce or gather food (option C).

Different ecosystems provide unique resources and support specific types of agriculture, hunting, and gathering practices. For example, in a forest ecosystem, there may be an abundance of edible plants, fruits, and nuts, which can form a significant part of the local diet.

This can shape the culinary traditions, food preferences, and cooking methods of the culture inhabiting that ecosystem. Similarly, the presence of specific animal species can impact hunting practices, animal husbandry, or fishing techniques, thereby influencing the culture's relationship with and dependence on these resources.

Moreover, the ecosystem's productivity and fertility can determine the overall agricultural practices and the success of crop cultivation. Cultures in fertile river valleys, for instance, may engage in intensive agriculture and develop complex irrigation systems to maximize food production. In contrast, cultures in arid or desert regions may rely on drought-resistant crops or adopt nomadic lifestyles centered around herding animals.

The availability of resources and the ecosystem's suitability for certain agricultural practices can also shape economic systems, social structures, and cultural beliefs related to land, nature, and sustainability. Therefore, the relationship between ecosystems and culture is intertwined, with ecosystems providing the foundation for food production and influencing various aspects of human society and identity.

What features may be common along active faults, such as the san andreas?

a. offset stream channel
b. scarp
c. drainage channels running parallel to fault
d. linear ridge and/or valley

Answers

All options are common along active faults such as the San Andreas. It includes offset stream channel, scarp, drainage channels running parallel to fault, linear ridge and/or valley.

An active fault is one that has a high probability of producing another earthquake in the near future. If there has been seismic activity during the previous 10,000 years or there has been movement that has been seen, geologists frequently consider a fault to be active. Geologic hazards associated with active faulting include those caused by earthquakes. Strong ground motion, surface faulting, tectonic deformation, landslides and rockfalls, liquefaction, tsunamis, and seiches are a few of the effects of movement on an active fault.

California is traversed by the San Andreas Fault, a continental transform fault, spanning around 1,200 kilometers. Its motion is right-lateral strike-slip and it creates the tectonic boundary between the Pacific Plate and the North American Plate.

Answers

Answer:

Options A, C, and D

Explanation:

Complete Question:

Averaged over the summer months, even though there are more hours of daylight at the Arctic Circle (66 ½°) compared to at 40° latitude, there is a lower maximum daily temperature at the Arctic Circle (66 ½°) compared to at 40°. This is because (choose all correct statements):

A. At the Arctic Circle, the sun’s rays travel through a thicker layer of atmosphere, reducing the amount of solar energy reaching the ground.

B. The increased cloud cover at the Arctic Circle during the summer reduces the amount of solar energy reaching the ground.

C. At the Arctic Circle, solar energy reaching the ground is spread over a smaller area, reducing the intensity of solar energy reaching the ground.

D. At the Arctic Circle, the daytime position of the sun in the sky is lower (closer to the horizon), reducing the intensity of solar energy reaching the ground.

The options that correctly explain the reason for low temperature over the Arctic circle are

A. At the Arctic Circle, the sun’s rays travel through a thicker layer of atmosphere, reducing the amount of solar energy reaching the ground. The arctic circle is the northernmost part of the world which consist of the Northern part of America and Asia, the Scandinavian Peninsula, Greenland, and the Arctic Ocean; The arctic circle is defined by the latitude of 66° 33' N the temperature of the warmest months in July and is below 10 ° C and thus has cool and cold summers (i.e it's characterized by long, cold winters and short, cool summers)

C. At the Arctic Circle, solar energy reaching the ground is spread over a smaller area, reducing the intensity of solar energy reaching the ground. Variations in solar radiance at the Earth's surface are a result of rays of the sun which have to travel through the thick layers of the atmosphere leading to some part of the earth's surface having a different reflection of sunlight. Thus less sunlight is received at the poles and hence the small area gets insolation.

D. At the Arctic Circle, the daytime position of the sun in the sky is lower (closer to the horizon), reducing the intensity of solar energy reaching the ground.

What is an exponential function?

An exponential function is a mathematical function of the form f(x) = a(b)^x

The parameters are defined as follows

the starting/initial value = a

the base = b

the exponents = x

The base is (1 + r) where r is the rate of change of the function

The base is what determines exponential growth or decay

Analyzing the function y = 7500 (1 + 0.3)ˣ

a = 7500

b = 1.3 since b > 1 this is a growth factor

r = 0.3 since this is positive this is a growth rate of chenge

Exponential functions are used to model phenomena that grow or decay at a constant percentage rate. Some examples of such phenomena include population growth, radioactive decay, and compound interest.

How have Earth's four systems interacted to shape the environment where you live?

Answers

Explanation:

The four systems of the earth are:

Biosphere: zone of lifeHydropshere : zone of waterAtmosphere: zone of gasesGeosphere: the solid and rocky earth

These four zones are intertwined and they greatly shape every environment on earth.

  In my locality, farming activities depends on an interplay between these spheres. As an agrarian community, the soil for cultivating crops is a product of weathering of the geosphere. This releases vital minerals that allow the plants to grow. Plants also need rainfall and moisture to grow. All living organisms on earth in fact require water. Water is used as one of the chemical substances for most chemical processes in living organisms.

The atmosphere is the source of gaseous exchange and where most weather elements are domiciled. Weather affects everything on earth from the rate of weathering of the geosphere to the levels of water in rivers.

The biosphere also interact with all the four systems directly.
