Continents float high because they are composed of granite, which is less dense than the materials under the ocean basins. The principle of isostasy allows for the buoyancy of lighter continental crust on the denser mantle, a process supported by geological studies.
Explanation:Continents float high because they are made up of granite, which has a relatively low density compared to the basalt and peridotite that underlie the ocean basins. This principle is similar to how icebergs float on the ocean, or how ice cubes float in a glass of ice tea. The granitic crust of continents extends to great depths in the Earth, much greater than the basaltic crust of the ocean basins, thereby allowing continents to stand higher than the ocean basins. The concept of isostasy helps explain this phenomenon, where the Earth's crust is in equilibrium with the more dense mantle below it, allowing for the buoyancy of the continents. Similar to how a piece of cork floats in wine or a hot-air balloon rises in the atmosphere, continents float on the mantle due to their lower density.
Throughout Earth's history, lighter materials within the crust found equilibrium with the upper mantle and floated higher, gradually forming the nuclei of continents. This development of continents is further supported by isotopic ratio studies, such as those conducted on the Canadian Shield, indicating that continental crust is significantly older and less dense than oceanic crust. Moreover, Antarctica, with the highest average elevation of any continent, showcases the variation in continental elevations, which mainly depends on the underlying crust's composition and density.

The temporary inflow of positive ions through an axon membrane is the
The temporary inflow of the positive ions through the axon membrane is the action potential. The action potential is responsible of having to transport signals through the cell from one cell to another in which helps electrical signals to be transported.
Final answer:
The temporary inflow of positive ions through an axon membrane, which changes the electrical charge of the neuron and allows it to transmit signals, is called the action potential. This crucial process in neural communication involves the opening of ion channels and the sequential movement of sodium ions along the axon.
Explanation:
The temporary inflow of positive ions through an axon membrane is known as action potential. This occurs when the cell membrane in a segment of an axon opens its gates due to an electrical signal from the dendrites, allowing positively charged sodium ions that were outside to flow in. As a result, the inside of the neuron becomes positively charged relative to the outside, leading to a reversal of charge. This electrical current, conducted down the axon, is an all-or-nothing event that happens when the membrane potential reaches a threshold of excitation. The action potential moves like a wave down the axon, with sodium ions entering through ion channels and triggering the next section of the axon to do the same, sequentially opening ion channels along the axon.
The process plays a critical role in how neurons send signals across the nervous system, enabling rapid communication throughout the body. This transient, but significant, change in the neuron's electrical charge facilitates the transfer of information via electrical and chemical signals, illustrating the complexity of neural communication and the fundamental mechanisms of brain function.
Piaget used the term ________ to describe changes in existing ways of thinking that occur in response to encounters with new stimuli or events.
The answer in the space provided is accommodation. This is the term being used in a way that describes the development or changes that occurs in comes with stimuli. It is usually involve with the individual’s ideas or schemas in regards with the experiences of a person that are new.
Accommodation, defined by Jean Piaget, is the adjustment of existing cognitive schemas to include new information or experiences. It is a fundamental aspect of his theory of cognitive development, allowing individuals to maintain cognitive balance and advance their understanding.
Piaget's Concept of Accommodation
Jean Piaget, a renowned developmental psychologist, introduced the concept of accommodation to describe the process by which individuals change or modify their existing schemas when they encounter new experiences or stimuli. This concept is integral to Piaget's theory of cognitive development. When someone encounters information or experiences that do not fit within their current understanding, they must adjust or accommodate their schemas to incorporate this new information.
Piaget's stages of cognitive development reveal that from birth to adulthood, individuals are constantly assimilating and accommodating new knowledge. For instance, a child learning about wallets comes to understand that a wallet is typically carried in pockets or purses, thus expanding their schema related to the concept of a wallet. Accommodation allows for the development of more complex and accurate understandings as a child grows and learns.
Indeed, accommodation is a critical mechanism for cognitive growth, as it compels the mind to reorganize or restructure knowledge when previous schemas prove to be inadequate. This is part of the lifelong process of achieving cognitive balance, which Piaget believed was essential.

In the past, a murderer might have been executed with the same weapon she used to commit the crime. according to michel foucault, this is an example of what?
It is an example of violence against body. The term of “violence” is actually little used by Foucault himself. Foucault did not give any explanation or did not put any forward theory for that because he was not that type of philosopher. He does not seek the psychological causes of aggression, but he inquires the sociological roots of civil violence.
According to Michel Foucault, this is an example of "violence against the body".
Michel Foucault is a standout amongst the most persuasive sociological scholars of the last 50 years. One of his key commitments to criminology is his emphasis on how the idea of wrongdoing control has moved from utilizing the risk of brutality and the dread of being physically rebuffed to control through observation – dread of apparently being accomplishing something wrong. Foucault's thought that the body and sexuality are social builds as opposed to characteristic marvels has made a noteworthy commitment to the women's activist evaluate of essentialism.

Michael's employer has recently experienced financial problems, and several rounds of layoffs have occurred. michael is still employed; however, it is likely that his _______ needs have become heightened. self-actualization esteem physiological safety
The correct answer is D. Safety
Explanation:
In psychology, the term needs refer to the elements an individual consider necessary in his life, these needs influence the behavior or actions of people and are part of their motivations. Additionally, needs are classified into five types including physiological needs that refer to essential needs such as food, water, etc; safety needs related to the security in different context including job; social needs including the need for love and affection; esteem needs related to the self-perception and esteem and self-actualization needs related to self-development. Considering Michael is experiencing financial problems and is mainly afraid of being fired from his job which is related to the safety need, in this case, his safety needs are being heightened as this situation makes Michael feel some pressure or urgency for safety or feeling he has a stable job. Thus, in this case, the type of needs that have become heightened are Michael's safety needs.
