Question 1

Which of the following best describes the difference between abiotic and biotic factors in an ecosystem?

Accepted Answer

Abiotic factors are nonliving components such as climate and soil, while biotic factors are living components such as plants and animals.

Question 2

Which of the following is an example of a microclimate?

Accepted Answer

The temperature difference between the north and south sides of a hill.

Question 3

Why do cities often experience more extreme weather than surrounding rural areas?

Accepted Answer

Cities have more buildings and pavement, which retain heat and alter wind patterns.

Question 4

Which equation best represents the relationship between temperature and latitude on Earth?

Accepted Answer

$$T = T_0$ - k|\phi|$$

Question 5

A mountain range causes a rain shadow effect. Which side of the mountain is likely to be arid, and why?

Accepted Answer

The leeward side, because descending air loses moisture and warms up.

Question 6

Which of the following is a major driver of large-scale climate patterns?

Accepted Answer

Latitude

Question 7

What is the primary reason for the lower concentration of sunlight at the poles compared to the equator?

Accepted Answer

Sunlight strikes the poles at a lower angle, spreading energy over a larger area.

Question 8

Which of the following best explains why ocean currents are important for global climate?

Accepted Answer

They distribute heat between the equator and the poles, accounting for about 40% of heat exchange.

Question 9

Which atmospheric cell is responsible for the abundant precipitation found near the equator?

Accepted Answer

Hadley cell

Question 10

If a region experiences regular El Niño events, what is a likely effect on its climate?

Accepted Answer

Warmer ocean temperatures and altered precipitation patterns.

Question 11

Which of the following is a biotic factor that could influence the survival of a plant species in a forest ecosystem?

Accepted Answer

Competition with other plants for sunlight

Question 12

Why are deep ocean regions typically richer in nutrients than surface regions?

Accepted Answer

Upwelling brings nutrient-rich water from the deep ocean to the surface.

Question 13

Which of the following best describes the difference between climate and weather?

Accepted Answer

Climate refers to long-term patterns over years or decades, while weather is the short-term atmospheric conditions.

Question 14

A city is located near a large body of water. Which of the following is a likely effect on its climate?

Accepted Answer

The city will have milder temperatures due to the thermal stability of water.

Question 15

Which of the following equations best represents the relationship between atmospheric pressure and elevation?

Accepted Answer

$$P = P_0$ e$$^{-kh}$$

Question 16

Which of the following is a direct effect of deforestation on local climate?

Accepted Answer

Altered precipitation and increased temperature extremes

Question 17

Which of the following best explains why higher elevations are generally cooler than lower elevations?

Accepted Answer

Atmospheric pressure decreases with elevation, causing air to expand and cool.

Question 18

Which of the following is a chemical abiotic factor that can influence the distribution of organisms in an environment?

Accepted Answer

Salinity

Question 19

Which of the following is a plausible consequence of global changes in ocean currents?

Accepted Answer

Altered heat distribution, potentially changing climate patterns on land.

Question 20

A plant species is found to survive better on the southern side of a hill in the Northern Hemisphere. Which factor most likely explains this pattern?

Accepted Answer

The southern side receives more sunlight, increasing thermal stability and survival.
