Outer Space
A meteor is a space rock—a meteoroid—that enters Earth's atmosphere. As the meteoroid falls toward Earth, the resistance—or drag—of the air on the rock makes it extremely hot. What we see is a "shooting star." That bright streak is not the rock itself, but rather the hot air around the rock.
Meteors usually happen between 50 and 75 miles above the Earth's surface.
Most meteors burn up completely before reaching the ground. When a meteoroid survives its trip through the atmosphere and hits the ground, it's called a meteorite.
Key points:
- Meteoroid: A space rock.
- Meteor: A meteoroid that enters Earth's atmosphere.
- Meteorite: A meteoroid that survives its trip through the atmosphere and hits the ground.

Please provide more context. I need to know what you're asking about to explain three patterns of it. For example, are you asking about:
- Programming patterns? (e.g., design patterns, architectural patterns)
- Behavioral patterns? (e.g., in psychology, sociology)
- Mathematical patterns? (e.g., number sequences, geometric patterns)
- Weather patterns? (e.g. El Nino, La Nina, Jet Stream)
- Sewing patterns?
- Or something else entirely?
Once you tell me what "it" refers to, I can give you a relevant explanation of three patterns.
Museums undertake a variety of preservation activities to protect their collections for future generations. These activities generally fall into the following categories:
- Preventive Conservation: This involves measures taken to minimize deterioration and damage to collections.
- Environmental Control: Maintaining stable temperature and humidity levels to prevent damage from fluctuations.
- Light Management: Controlling light exposure to reduce fading and degradation of sensitive materials.
- Pest Management: Implementing strategies to prevent and control pest infestations that can damage collections.
- Proper Storage and Handling: Using appropriate storage materials and handling techniques to minimize physical damage.
- Active Conservation: This involves direct treatment of objects to stabilize their condition, repair damage, or reverse deterioration.
- Cleaning: Removing dirt, dust, and other surface accretions that can damage or obscure objects.
- Stabilization: Strengthening weakened materials to prevent further deterioration.
- Repair: Mending breaks, tears, and other physical damage.
- Restoration: Returning an object to its original appearance or condition (this is less common and only done when appropriate).
- Documentation: Maintaining detailed records of the condition, treatment, and provenance of objects.
- Condition Reports: Documenting the condition of an object before and after treatment.
- Treatment Records: Recording the materials and methods used in conservation treatments.
- Photographic Documentation: Taking photographs to document the condition of an object and the progress of treatment.
- Research: Conducting research to better understand the materials and techniques used in the creation of objects, as well as the causes of deterioration.
These activities are carried out by trained conservators, conservation scientists, and other museum professionals.

Alexander Pope, a prominent figure in the 18th-century literary scene, masterfully employed satire to critique various aspects of his society. Here's a breakdown of the common targets of his satirical wit:
-
Social Follies and Vices:
- Vanity and Superficiality: Pope often satirized the obsession with appearances and the pursuit of trivial matters prevalent in high society.
- Gossip and Scandal: The spread of rumors and the preoccupation with the lives of others were frequent targets of his satire.
- Materialism and Consumerism: He criticized the growing emphasis on wealth and possessions as measures of worth.
- Social Climbing: Pope mocked those who sought to elevate their social status through deceit and manipulation.
-
Political Corruption and Ineptitude:
- Abuse of Power: Pope criticized those in positions of authority who used their power for personal gain.
- Political Intrigue: He satirized the complex and often self-serving machinations of politicians.
- Ineffective Leadership: Pope mocked leaders who were incompetent or out of touch with the needs of the people.
-
Literary and Intellectual Pretensions:
- Bad Poets and Critics: Pope often lampooned those who produced poor quality literature or offered shallow criticism.
- Pedantry and Intellectual Snobbery: He satirized those who used their knowledge to intimidate or exclude others.
- The Misuse of Learning: Pope criticized those who used their education for frivolous or harmful purposes.
-
The Battle of the Sexes:
- Exaggerated Femininity/Masculinity: Pope sometimes satirized extreme or artificial displays of gender roles.
- The Fickleness of Love: He mocked the fleeting and often superficial nature of romantic relationships.
- Marital Discord: Pope satirized the conflicts and misunderstandings that could arise between husbands and wives.
Examples in His Works:
- The Rape of the Lock: Satirizes the triviality and vanity of high society through a mock-epic narrative.
- The Dunciad: Attacks bad poets and critics, portraying them as agents of dullness and ignorance.
- An Essay on Criticism: Offers a satirical commentary on the state of literary criticism and the qualities of a good critic.
Through his sharp wit and insightful observations, Pope aimed to expose the follies and vices of his time, prompting reflection and reform.
