Scoria cones are almost entirely made of tephra from ejected basaltic rocks. Although bomb-size bits and lava spatter may also be found, lapilli-sized fragments make up the majority of the tephra.
The most frequent kinds of volcanic Scoria cones are cinder cones, also known as scoria cones or pyroclastic cones. They develop as a result of lava pieces being blown into the air by ferocious eruptions, solidifying, and then falling as cinders surrounding the volcanic vent. Layers of pebble-sized or larger cinders and layers of ash make up cinder cones. bigger blocks and explosives from the volcano. The majority are composed of Scoria cones pieces that were ejected from the volcano together with gas-rich magma. Cinder cones have very little strength since they are composed almost entirely of loose particles. The majority of Scoria cones is made up of glassy pieces and might have phenocrysts. An examination of scoria discovered in Yemen revealed that it was mostly made of volcanic glass and a trace amount of zeolites (e.g. clinoptilolite). The Greek word for rust, skria, is whence the word scoria originates.

Method to mine a mineral deposit which includes open pit mining quarrying placer mining and strip mining
Answer:
Surface mining
Explanation:
The method covered in the question above is called Surface mining.
Surface mining refers to the practice of extracting ores that are in the soil at medium and shallow depths, that is, they are close to the surface. This type of extraction of ores, exploits the mineral deposits until it causes its depletion, creating small depressions in the land that can be used to create landfills. The main ores found in this type of extraction are: limestone, clay, marble, coal, plaster, among others.

Please find the value of x
some comets disappears forvers give reason in 2 points
For the line segment whose endpoints are A(0,0) and B(4,3), find the X coordinate for the point located 2/3 the distance from a to b.
Answer:
2.7
Explanation:
Short answer: took the test
Actual explanation: Finding the coordinate means that we need to find the x distance first between the two points. So, the coordinates are A (0, 0) and B (4, 3).
- the x distance: 0 to 4, which is 4 units.
Using the 4 units and the fraction, 2/3 because we want to find it 2/3 the distance a-b, we set it up like this
-2/3 * 4/1 (4/1 comes from the x-distance, which is 4 units) and get 8/3 (by multiplying across) which is 2.666,
and we round it to get 2.7, which is the final answer.
they are only asking for the x-distance, which is why we only solved for the x distance.
hope this helps :)
~addison~
Two unique points on a line define the boundaries of a line segment. A line segment is sometimes referred to as a section of a line that links two places.
2.7 : In order to calculate the coordinate, we must first determine the x distance between the two points. So, A (0, 0) and B are the coordinates (4, 3).
- the x distance, which is 4 units from 0 to 4.
This is how we set it up using the 4 units and the fraction 2/3 to get the distance between a and b.
-2/3 * 4/1 (4/1 is the result of the x-distance, which is 4 units), which produces 8/3 (by multiplication across), which is 2.666,
2.7 is the result after rounding, which completes the equation.
We just provided a solution for the x distance since that is all they asked for.

Describe two effective means of preventing the spread of malaria.
Answer:
There are two central blocking systems: Protective bed nets treated with long-lasting instinct poison prevent bites from malaria-infected mosquitoes and kill them. Nets should be available for free or at low prices because of high subsidies. There should be one net per two people who are at risk of being infected.
Explanation:
Presently, Mosquito control and mosquito-bite prevention are the two key approaches used to prevent malaria.
How can you prevent the spread of malaria?Personal protection measures against mosquito bites- Malaria is primarily transmitted at night since the majority of Anopheles mosquitoes bite at night. Wearing clothing that covers the majority of the body, using insect repellent on exposed skin, and using mosquito bed nets are all ways to prevent mosquito bites. Age and status affect the kind and strength of repellents.Mosquito prevention- The effectiveness of vector control strategies is dependent on the vector species, the biology of the mosquito, the epidemiological situation, the cost, and the acceptability to the people. The primary current approaches concentrate on reducing human-mosquito interaction and eliminating larvae through environmental management.To learn more about malaria

In World Geography you will examine people, places, and environments at local, regional, national, and international scales from the spatial and ecological perspectives of geography. You will learn the influence of geography on events of the past and present with emphasis on contemporary issues. A significant portion of the course centers around the physical processes that shape patterns in the physical environment; the characteristics of major landforms, climates, and ecosystems and their interrelationships; the political, economic, and social processes that shape cultural patterns of regions; types and patterns of settlement; the distribution and movement of the world population; relationships among people, places, and environments; and the concept of region. You will analyze how location affects economic activities in different economic systems. You will identify the processes that influence political divisions on the planet and analyze how different points of view affect the development of public policies. You will compare how cultures shape the characteristics of regions and analyze the impact of technology and human modifications on the physical environment. You will use problem-solving and decision-making skills to ask and answer geographic questions.
