How do volcanoes affect the atmosphere lithosphere hydrosphere and biosphere?
Answer:
Explanation:
In the lithosphere, volcanic eruptions can form new rocks or destroy existing life in the area.
Volcanoes effect on the hydrosphere by a volcanic eruption can discharge pollution in the air that can pollute water bodies that are located nearby the site of the volcano
When volcanoes erupt, they push a mixture of gases and particles into the air. Some of them, such as ash and sulfur dioxide, have a cooling effect along with reflecting sunlight away from the earth.
Volcanic eruptions affect the biosphere by releasing gas and ash into the air. This kills plants, which makes it hard for some animals to find food and in turn damages the food system in that habitat.

What data do GIS and light detection and ranging (LIDAR) technologies provide to Portland city officials?
LiDAR is an acronym for ‘light’ and ‘radar,’ a tool developed to detect targets and to use reflected light off of objects as a kind of visual sonar. Light Detection And Ranging (LiDAR) can determine how far objects are away from each other by shining a laser onto a target and analyzing the light that bounces back. LiDAR is used to create incredibly detailed maps in addition to assisting researchers in the fields of geography, archeology, geology, seismology, atmospheric sciences, laser studies, and much more.
LiDAR’s first applied use was in the 1960s and came soon after the invention of lasers. Used in combination with radar, LiDAR was originally used in atmospheric studies to measure clouds by the National Center for Atmospheric Research. LiDAR later became more publically known when the Apollo 15 mission used it to map the surface of the moon more accurately than ever before.

financial aid
Visual aid, because your visualizing it
"The correct answer is c. visual aid.
Graphs and charts are tools that present data or information in a visual format, making it easier to understand and interpret. They are designed to convey complex information quickly and clearly, which is why they are categorized as visual aids. Visual aids can include various forms of illustrations, such as diagrams, pictures, maps, and videos, in addition to graphs and charts. They are commonly used in presentations, reports, and educational materials to enhance comprehension and retention of the presented material. Audio aids, on the other hand, involve sound-based tools like music, speech, or sound effects, and are used to support learning or to convey messages through hearing. Internal aids refer to strategies or tools that an individual uses mentally, such as mnemonics or visualization techniques, to remember or process information. Financial aid typically refers to funds provided to students or individuals to help them pay for education or other services, and is not related to the presentation of information."

Explain how the elements present on the surface of a star can be identified using bright line spectra
Bright line spectra can be used to identify the elements present on the surface of a star. Absorption lines, which are created when specific elements absorb certain wavelengths of light, can be observed in the star's spectrum. By comparing these absorption lines to laboratory measurements, astronomers can determine the composition of the star's surface.
Explanation:Elements present on the surface of a star can be identified using bright line spectra. When light from a star passes through a prism or a diffraction grating, it gets dispersed into a spectrum. This spectrum consists of dark lines, known as absorption lines, which are created when specific elements in the star's atmosphere absorb certain wavelengths of light. By comparing the absorption lines in the star's spectrum to laboratory measurements of known elements, astronomers can determine the composition of the star's surface.

What does the theory of plate tectonics state about the earth's surface?
The theory of plate tectonics states that the Earth's surface is made up of a number of large , rigid plates that are constantly moving.
What are these plates made of ?These plates are made up of the Earth's crust and upper mantle, and they move about at rates of a few centimeters per year .
The movement of the plates is driven by convection currents in the Earth's mantle. These currents are caused by the uneven heating of the mantle , which causes the hot , less dense material to rise and the cooler , denser material to sink .
