Answers

Answer 1
Answer: The correct answer should be Cinder Cone, that is A. 

They are often made out of pyroclastic material. Stratovolcanos are made out of various materials, while shield volcanoes also often mix with elements such as water and other layers of basalt created from previous eruptions.
Answer 2
Answer:

Final answer:

The cinder cone and shield volcano are generally formed from only one type of igneous material. The stratovolcano is formed from alternating layers of different types of volcanic material.

Explanation:

The cinder cone and shield volcano are generally formed from only one type of igneous material. The cinder cone volcanoes are mostly formed by eruption of pyroclastic material which is ejected from a single vent. They have steep sides with a bowl-shaped crater at the summit. Shield volcanoes, on the other hand, are primarily formed from fluid basaltic lava flows which emanate from one or several vents. The stratovolcano is not included because it is formed from alternating layers of different types of volcanic material like ash, lava, and cinders.

About 90% of the world lacks safe drinking water. A. True B. False

Answers

Answer:true

Explanation:

Final answer:

The statement suggesting that 90% of the worldlackssafedrinkingwater is false. Discrepancies exist in access to clean, drinkable water, especially in the developing world. However, the majority of the world does have access to water.

Explanation:

The statement that about 90% of the world lacks safe drinking water is FALSE. While access to safe water and sanitation resources are significant concerns, especially in low-income countries, the situation is not as dire as suggested by the question. According to a 2014 UNICEF report, nearly half the population of the developing world lacks improved sanitation facilities.

The WorldHealthOrganization(WHO) provides data tracking health-related circumstances across 193 countries. It reveals that the majority of the world does have access to water, but the central problem lies with discrepancies in available clean drinkable water. Fresh water, which constitutes only 2.5% of Earth'swater, faces the challenge of accessibility. Less than 1% of this fresh water is easily accessible to living organisms.

Further, water accessibility can be significantly affected by factors such as globalpandemics, pollution, climate change, or lack of infrastructure to produce clean drinking water. Moreover, the cost to obtain safe water can hinder survival and upward mobility for many, especially those in underprivileged areas. Ultimately, while the statement at hand is not 100% accurate, it does underscore the importance of addressing global disparities in access to safe, potable water.

I got my answer from

www.weegy.com?r=UGIJRBMZ

Final answer:

An archipelago is the term for a group or chain of islands, such as the Hawaiian Islands. A monsoon, schism, and caste do not refer to a group of islands.

Explanation:

A group or chain of islands is called an archipelago. An example of an archipelago would be the Hawaiian Islands, which consists of eight major islands and numerous smaller ones. Other examples include the Florida Keys and the Philippines. The term 'monsoon', 'schism', and 'caste' are not used to describe a group or chain of islands. A monsoon pertains to a season of high rainfall, typically in South and Southeast Asia. 'Schism' refers to a division or disunion, especially one that is caused by disagreement in an organization. And a 'caste' is a social class in societies that practice this form of social stratification, like in India.
