Chapter 16 Some scientists suggest we can increase the amount of carbon dioxide removed from the atmosphere by adding iron to stimulate productivity in tropical oceans. Why has iron fertilization not been widely adopted as a solution to global warming? Choose all that apply. Iron fertilization was found to be ineffective in terms of increasing productivity. Iron fertilization creates dead zones. Iron is not widely available. Iron fertilization can exacerbate ocean acidity. Iron is expensive.

Which type of problem(s) does reinforcement learning solve? Choose all that apply.

Chapter 16 What causes the greenhouse effect? Atmospheric gases, such as carbon dioxide, absorb sunlight, causing the atmosphere to heat up. The oceans absorb solar energy and trap heat, making the Earth warmer. Greenhouse gases lead to polar ice cap melting, making the Earth warmer. Sunlight is absorbed by the Earth’s surface, reradiated as infrared energy, and absorbed by atmospheric gases. Greenhouse gases absorb ozone, leaving the Earth unprotected from ultraviolet radiation.

For the Cartpole problem in which the agent had to learn to balance a pole on a wheeled cart, we discretized the state space in order to use the tabular Q-learning algorithm. What would have happened if we hadn’t discretized the state space?

Chapter 16 Complete the following statements.

Chapter 16 Match each greenhouse gas with its primary source or characteristic.

Chapter 6 Air always moves from _____ atmospheric pressure regions to _____ atmospheric pressure regions. high; low low; high low; low high; high

Chapter 6 Match the term with the location.

Chapter 6 The apparent deflection of air masses to the right or left (depending on latitude) as they move from one latitude to another is called the ________. Cyclonic effect Coriolis effect Ekman spiral CIrcular effect
