Video Transcript

we have some questions about the climate here. So number one over the last 100 years, CO two levels have not had a clear friend either direction folks. There's been a gradual rise. So there are fluctuations but it looks something like it's been like this, it's gradually increasing. Two scientists are not worried about extinction rates because populations can shift ranges or adapt. This is also false. We're very worried there is an increasing extinction rates and it's because the change is very rapid from an evolutionary time scale. Um and populations often cannot adapt or cannot move and in some cases it's a global environment that's changing. For example, the oceans are becoming more acidic so there's nowhere to move to. three. If a particular species is introduced in one location, it can be introduced to others. This is also false because the conditions may be different in different locations. Um conditions vary mobile location and that decides if if a species will be invasive or not. For example, one location, they have predators that start eating the introduced species and they may be absent in another and without natural predators may be an invasive species. That could be one example of differences. Four, if we stopped adding greenhouse gasses, what would happen to be syllables, they would continue to rise rise for many years. So the problem is, but it's not as simple as we release a bunch of CO 21 year and it immediately has an effect. The effect is baked in. So we have we will continue to see the impact of the gas is released in the last few decades. In the next few decades, it's a very slow effect. And also it is magnified because we are bringing out um bring out water from glaciers. For example, bringing out gasses have been stored in glaciers. So it's a run on effect. So yes, if we stop today, we would still be affected for many years. five. Which of these describes an invasive species. So an invasive species has um no natural enemies and it out competes. The native species, they tend to have quite a rapid reproduction at least in that environment. So um often an invasive species is a species that is what we call our selected, which means they have a lot of offspring but they don't take very good care of them. There's a very high infant mortality and a very low life expectancy. But if they get into an environment where they aren't predated on and they have very good conditions, then that's high reproductive rate means face their population massively increases. Also, no natural enemies is very common for an invasive species. Perhaps there's no predators. Two, yeah. Two keep down the population. So those are the two main factors for so as far as Oh yeah. Also tolerance of a wide range of environments is a benefit. So we'll put that in as well. Yeah, wide habitat tolerance because it has to be tolerant of whatever new habitat it finds itself in. But it isn't immediately adapted to. It has. I mean, it hasn't evolved to cope with, but because it has a wide habitat tolerance, you can put it in a lot of different places, sabes through the answers.

Elements and Their Atoms In chemistry and physics, an element is a substance that cannot be broken down into a simpler substance by chemical means. A pure element is a substance consisting of a single type of atom, with its chemical properties determined by that atom's atomic number, which is the number of protons in its nucleus. Examples of elements include carbon, oxygen, aluminum, iron, gold, copper, mercury, and lead.

The Elements of Life In biology, the elements of life are the essential building blocks that make up living things. They are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. The first four of these are the most important, as they are used to construct the molecules that are necessary to make up living cells. These elements form the basic building blocks of the major macromolecules of life, including carbohydrates, lipids, nucleic acids and proteins. Carbon is an important element for all living organisms, as it is used to construct the basic building blocks of life, such as carbohydrates, lipids, and nucleic acids. Even the cell membranes are made of proteins. Carbon is also used to construct the energy-rich molecules adenosine triphosphate (ATP) and guanosine triphosphate (GTP). Hydrogen is used to construct the molecules water and organic compounds with carbon. Hydrogen is also used to construct ATP and GTP. Nitrogen is used to construct the basic building blocks of life, such as amino acids, nucleic acids, and proteins. It is also used to construct ATP and GTP. Oxygen is used to construct the basic building blocks of life, such as carbohydrates, lipids, and nucleic acids. It is also used to construct ATP and GTP. Phosphorus is used to construct the basic building blocks of life, such as carbohydrates, lipids, and nucleic acids.

FAQs

Is global warming a negative feedback loop? ›

Observations and modelling studies indicate that there is a net positive feedback to warming. Large positive feedbacks can lead to tipping points—abrupt or irreversible changes in the climate system—depending upon the rate and magnitude of the climate change.

What type of feedback loop is global warming? ›

Global warming is altering Earth's weather patterns dramatically. A warmer atmosphere absorbs more water vapor, which in turn traps more heat and warms the planet further in an accelerating feedback loop.

What is an example of a negative climate feedback loop? ›

A good example of a negative feedback mechanism will be if the increase in temperature increases the amount of cloud cover. The increased cloud thickness or amount could reduce incoming solar radiation and limit warming.

How is global warming a positive feedback loop? ›

The feedback comes when the warmer atmosphere results in more evaporation of water on the surface of the Earth. As the water from the Earth evaporates, it turns into water vapour in the atmosphere. This water vapour thus causes even more warming of the atmosphere, creating a self-reinforcing cycle of heating.

What is a negative feedback in the context of global warming quizlet? ›

What is a negative feedback in the context of global warming? The absorption of carbon dioxide by plants and the ocean increases. Processes that increase the uptake and sequestration of atmospheric carbon dioxide have a negative feedback effect.

What is a negative feedback loop simple? ›

What Is a Negative Feedback Loop? A negative feedback loop is a reaction that causes a decrease in function. It occurs in response to some kind of stimulus. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system.

What are some examples of negative feedback? ›

Examples of processes that utilise negative feedback loops include homeostatic systems, such as: Thermoregulation (if body temperature changes, mechanisms are induced to restore normal levels) Blood sugar regulation (insulin lowers blood glucose when levels are high ; glucagon raises blood glucose when levels are low)

What is feedback loop in climate? ›

What is an example of positive feedback loop? ›

Positive feedback mechanisms are rare. It amplifies changes rather than reversing them. The release of oxytocin from the posterior pituitary gland during labor is an example of positive feedback mechanism. Oxytocin stimulates the muscle contractions that push the baby through the birth canal.

Which is an example of a climate feedback quizlet? ›

Climate-Feedback Mechanisms. Positive-Feedback Mechanisms. Example: Warmer temperatures at high latitudes cause sea ice to melt, which is replaced with a lower-albedo ocean, which increases solar radiation absorbed at Earth's surface, which increases temperature.

What is a climatic example of negative feedback quizlet? ›

Plant growth is a negative feedback. -plants absorb co2. -the increase in plant growth means that more CO2 is being absorbed from the atmosphere by plants.

Which of the following is a negative feedback to a cooling climate? ›

-The decrease in clouds in a cooling climate acts as a negative feedback by reflecting less sunlight, making it warmer. -Clouds reflect incoming sunlight, so they are always a negative feedback to climate.

What is an example of a positive feedback loop related to global warming? ›

As mentioned, positive feedback loops will accelerate a response, making the climate much warmer or colder. An important example is the water vapor feedback loop. Although water vapor is a greenhouse gas, it has very little effect on the external factors controlling the climate, unless “pushed” from within.

What is positive and negative feedback loop? ›

Positive feedback loops enhance or amplify changes; this tends to move a system away from its equilibrium state and make it more unstable. Negative feedbacks tend to dampen or buffer changes; this tends to hold a system to some equilibrium state making it more stable.

What are positive and negative feedbacks in the climate system? ›

Climate feedbacks: processes that can either amplify or reduce the effects of climate forcings. A feedback that increases an initial warming is called a "positive feedback." A feedback that reduces an initial warming is a "negative feedback."

What is an example of a positive feedback loop related to global warming quizlet? ›

The increase in clouds in a warming climate acts as a positive feedback by trapping more heat, making it warmer. The decrease in clouds in a cooling climate acts as a negative feedback by reflecting less sunlight, making it warmer.

What is a stabilizing feedback loop in the climate system quizlet? ›

A negative feedback counteracts some of the external forcing, tending to stabilize the state variable. A positive feedback makes the temperature change larger than it would have been without the feedback, amplifying the temperature change.

Which of the following statements is an example of a negative feedback loop regarding changes in global climate? ›
