The Columbia Plateau in the northwestern United States is an excellent example of ________. silica-rich lava flows flood basalts an eroded shield volcano pyroclastic flow deposits

Answers

Answer 1

The Columbia Plateau in the northwestern United States is an excellent example of "flood basalts."

Flood basalts are vast accumulations of basaltic lava that spread over large areas, typically resulting from prolonged volcanic activity. The Columbia Plateau was formed by a series of massive basaltic lava flows that originated from fissures in the Earth's crust, covering an extensive region of Washington, Oregon, and Idaho. These lava flows occurred during a geologic event known as the Columbia River Basalt Group, which took place between approximately 17 million and 6 million years ago. The resulting basaltic layers are now exposed and visible across the Columbia Plateau, creating a distinctive landscape characterized by extensive basalt formations and canyons.

How are igneous rocks formed?​

Answers

Explanation:

Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there.

hope it helps u

pls mark me as branliest

Answer:

Igneous rocks are formEd from the cooling and solidification of lava or magma. Furthermore, there are two types of igneous rocks: intrusive and extrusive.

Intrusive igneous rocks are formed when magma cools slow and it forms large crystals.

Extrusive igneous rocks are formed when lava cools quickly and forms small or no crystals. It may be vesicular meaning that it may contain air bubbles.

what is houston texas temperature ?

Answers

The houston texas temperature is around 22-25 degree celsius.

A substance or system's temperature is a measurement of the average kinetic energy of its constituent particles. To put it simply, it is a gauge for determining how hot or cold something is.

Although Kelvin (K) and Rankine (°R) can also be used to measure temperature, Celsius and Fahrenheit are the most common units used. The freezing and boiling points of water serve as the basis for the Celsius and Fahrenheit scales, while absolute zero, the point at which all molecular motion ceases, serves as the basis for the Kelvin and Rankine scales.

A humid subtropical climate with tropical influences best describes Houston's climate. Normal monthly temperatures are 53.1 °F (11.7 °C) in January and 84.6 °F (29.2 °C) in August.

Why is poor weather usually associated with a low pressure system?

in the northern hemisphere what is the difference in how the sides of a low pressure system develop during the formation of a mid latitude cyclone

Answers

In the northern hemisphere, the sides of a low pressure system in the formation of a mid-latitude cyclone develop in a counterclockwise direction. This is due to the Coriolis effect, which is caused by the Earth's rotation and deflects moving objects to the right in the northern hemisphere. This results in the counterclockwise rotation of the cyclone and the development of the warm front on the eastern side and the cold front on the western side.

During the formation of a mid-latitude cyclone in the northern hemisphere, the sides of a low-pressure system develop differently. The side of the low-pressure system to the east of the center of the cyclone experiences a stronger pressure gradient force due to the faster movement of the jet stream in that direction. As a result, the air on this side of the low-pressure system rises more rapidly, leading to stronger upward vertical motion and the development of more intense precipitation and thunderstorms. On the other hand, the side of the low-pressure system to the west of the center of the cyclone experiences weaker pressure gradients due to the slower movement of the jet stream in that direction. As a result, the air on this side rises less rapidly and tends to form more stratiform clouds, leading to less intense precipitation and a more gradual decrease in atmospheric pressure. Overall, the different pressure gradients on the two sides of the low-pressure system contribute to the development of a complex weather system that includes a range of precipitation types and wind patterns, as well as changes in temperature and humidity. The exact positioning and strength of these fronts can be influenced by the latitude of the cyclone's formation, as the Coriolis effect is stronger at higher latitudes. In the Northern Hemisphere, the development of a low-pressure system in a mid-latitude cyclone involves the Coriolis effect, which causes winds to move counterclockwise around the low-pressure center. This rotation is due to the Earth's rotation and the variation in latitude, resulting in a distinct pattern of convergence and divergence that shapes the cyclone's structure.

Answers

Mafic rocks are less dense and more fluid than ultramafic rocks

Mafic rocks have a higher proportion of silica compared to ultramafic rocks. This makes them less dense and more fluid, so they can flow more easily. Mafic rocks are a type of igneous rock that is dark and rich in iron and magnesium. Ultramafic rocks are similar to mafic rocks, but they have a lower percentage of silica and more iron and magnesium. Mafic rocks are abundant in the ocean floor, while ultramafic rocks are found in the mantle of the Earth's crust. Mafic rocks are denser than ultramafic rocks, which is why they sink lower into the Earth's mantle than ultramafic rocks. Mafic rocks are also more common on the Earth's surface than ultramafic rocks, as they are more likely to be exposed by erosion or volcanic activity. Mafic rocks are used in a variety of industries, including construction, agriculture, and manufacturing. They are commonly used as building materials, road aggregates, and fertilizers, as well as in the production of steel and other metals.

In conclusion, mafic rocks are less dense and more fluid than ultramafic rocks. They have a higher proportion of silica and are more common on the Earth's surface.

The Appalachians are one of the earliest mountains on Earth, having been shaped by the constant action of water on their surface as well as by great tectonic movements deep below the earth's crust. The oldest crystallised rocks come first.

Long periods of sedimentation and explosive eruptions alternated between around 1.1 billion and 541 million years ago, as during Precambrian epoch, to form rocks and then treat them to such intense heat and pressure that they were altered into sequences of metamorphic rocks.

It is also transmitted if people are sharing needles or syringes. So prevention would be done by practicing safe sex, testing ourselves before we have kids, and using clean syringes and needles that nobody used before us. Besides these, there is a vaccination that is safe and works.

a model for earth elevation based only on oceanic crust being denser than continental crust results in

Answers

Reasonable estimates of crustal thickness and crustal densities

A model for Earth's elevation based only on oceanic crust being denser than continental crust results in a phenomenon called isostasy.

Isostasy is a state of balance or equilibrium between the lithosphere (the rigid outermost layer of Earth's crust) and the underlying asthenosphere (a more ductile and less rigid layer in the upper mantle). According to the theory of isostasy, the lithosphere "floats" on the asthenosphere, and the elevation of the lithosphere is determined by the balance between its own weight and the buoyant force of the asthenosphere.

When the oceanic crust is formed at mid-ocean ridges and moves away from the ridge, it cools and becomes denser. As a result, it sinks lower into the mantle than the continental crust, which is generally less dense. The denser oceanic crust, therefore, exerts a greater weight on the asthenosphere than the less dense continental crust. The asthenosphere responds by flowing upward beneath the continental crust, supporting it, and maintaining its elevation.

Therefore, the model for Earth's elevation based on oceanic crust being denser than continental crust results in a dynamic equilibrium in which the elevation of the lithosphere is determined by the balance between the weight of the lithosphere and the buoyant force of the asthenosphere.
