how many seismographs are needed to locate an earthquake

Igneous rocks formed at mid-ocean ridges are primarily basaltic in nature. Basaltic rocks are dark-colored, dense, fine-grained rocks that are usually composed of minerals such as olivine, pyroxene, and feldspar.

The mid-ocean ridges are formed by the movement of tectonic plates, which results in volcanic eruptions that produce lava flows. When the lava cools down, it solidifies into basaltic rocks. These rocks are formed through a process known as solidification, in which the molten material (magma) cools and solidifies.

In the case of mid-ocean ridges, the magma comes from the Earth's mantle, which is a layer of the planet that lies between the crust and the core.The mantle is composed of several layers, including the lithosphere, the asthenosphere, and the lower mantle.

The lithosphere is the outermost layer of the mantle and is made up of the Earth's crust and the uppermost part of the mantle. The asthenosphere is a semi-solid layer of the mantle that lies just beneath the lithosphere and is responsible for the movement of tectonic plates.

The b) market economy is the system that has complete public ownership of the means of production.

A market economy is a system where the means of production are owned and operated by private individuals, rather than by the government.

This type of economic system exists in many countries around the world, and is based on the principles of free enterprise and competition. It is characterized by the production and exchange of goods and services at prices determined by the forces of supply and demand.

This system allows individuals to make decisions regarding the use of resources, production, and consumption of goods and services, and to make a profit from their investments.

The result is a more efficient and effective allocation of resources and an increase in overall wealth.

Explanation:

When the water level started to go down in Dry Gulch, people took the step of digging more aquifer to fulfill the requirement of the water. They did not took the initiative of asking a sustainable use of water or deciding to save water. In turn, they adopted to extract more water by digging more wells. On the other hand, the people in the other town decided to save water and agreed upon using the water carefully. Hence, in this scenario, the use of water had gone high in Dry Gulch than the other town.

One river that begins its journey in the Himalayas, flows into a valley, and joins the Ganges river on the plains is the Yamuna river. The Yamuna river is one of the major tributaries of the Ganges river and is the longest tributary in India.

The Yamuna river originates in the Yamunotri glacier in the Himalayas and flows through the states of Uttarakhand, Himachal Pradesh, Haryana, Delhi, and Uttar Pradesh, covering a total distance of around 1,376 km.

As the river flows from its source in the mountains down into the plains, it enters a broad valley known as the Yamuna Valley. This valley is home to numerous towns and cities, including the city of Agra, which is famous for the Taj Mahal.

Eventually, the Yamuna river joins the Ganges river at Allahabad in Uttar Pradesh. The confluence of the two rivers is considered to be a highly sacred site for Hindus and is the location of the Kumbh Mela, which is the world's largest gathering of people.

Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock. The word metamorphic comes from Greek and means To Change Form

Explanation:

The core is the very middle of the Earth, It is a solid ball of melted rock.

The crust is split into sections which are called plates.

False. The position of the north and south magnetic poles is not constant over human time scales.

The Earth's magnetic field is dynamic and undergoes changes over time. The magnetic poles, both the north and south, exhibit movement and can shift their positions. This phenomenon is known as geomagnetic secular variation. While the rate and magnitude of pole movements can vary, they have been observed to shift slowly over geologic time.

Scientists study the Earth's magnetic field and its changes by monitoring the movement of magnetic poles. Historical records, as well as data from satellite measurements and geomagnetic surveys, provide evidence of pole movement. These shifts are a natural part of the Earth's magnetic cycle and are influenced by complex interactions within the planet's molten iron outer core.

The movement of magnetic poles has implications for navigation systems, particularly for compass users and satellite-based navigation technologies. To account for these changes, navigational charts and systems are periodically updated to ensure accurate positioning. Therefore, it is important to acknowledge that the position of the north and south magnetic poles is not fixed and can change over time.

To complete his proof using the AAS postulate, Adrian needs the information that the side lengths of triangle POV are congruent to the corresponding side lengths of triangle TSC.

This additional information will allow him to establish the congruence of the two triangles and complete his proof. The AAS (Angle-Angle-Side) postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent. In this case, Adrian has already identified that angle P is congruent to angle T and angle O is congruent to angle S.

However, for the AAS postulate to be applied, Adrian also needs to establish the congruence of the corresponding side lengths of triangle POV and triangle TSC. Without this information, he cannot prove the congruence of the triangles solely based on the given angle congruences.

To complete his proof, Adrian should examine the lengths of the sides of triangle POV and compare them to the corresponding sides of triangle TSC. If he finds that the side lengths of POV are congruent to the corresponding side lengths of TSC, he can then state that triangle POV is congruent to triangle TSC by the AAS postulate.
