________ describes how an entire suite of silicate minerals can form from a single basaltic magma as it cools and crystallizes.
Answers
The process you are referring to is called Bowen's reaction series. Bowen's reaction series describes the sequential crystallization and formation of various minerals from a basaltic magma as it undergoes cooling and solidification.
The series Bowen's reaction was proposed by the Canadian geologist Norman L. Bowen in the early 20th century. According to Bowen's reaction series, as a basaltic magma cools, minerals with higher melting points begin to crystallize first, while those with lower melting points crystallize later. At high temperatures, the first minerals to crystallize from the magma are calcium-rich plagioclase feldspar and olivine. As the temperature continues to drop, pyroxene and amphibole minerals form. As the magma cools further, biotite mica and potassium feldspar crystallize. Finally, at the lowest temperatures, quartz and muscovite mica can form. The sequential crystallization of minerals in Bowen's reaction series is driven by the fact that different minerals have different chemical compositions and melting points.

________ increases the volume of water in and decreases the lag time of a flood.
Answers
Urbanization increases flood volume and decreases flood lag time by replacing natural surfaces with impervious ones, leading to more runoff and faster response to rainfall. So, the correct answer is Urbanization.
Urbanization increases the volume of water in and decreases the lag time of a flood. When an area undergoes urban development, natural surfaces such as soil and vegetation are replaced with impervious surfaces like pavement and buildings. This change in land cover reduces the amount of infiltration and increases surface runoff during rainfall events.
With less infiltration, more water flows over the ground and into storm drains, creeks, and rivers, resulting in higher volumes of water during a flood. Additionally, the reduced lag time refers to the quicker response of urbanized areas to rainfall, as water travels more rapidly over impervious surfaces compared to natural landscapes.
The calculation of flood volume and lag time involves various factors such as rainfall intensity, catchment characteristics, and land cover changes. Mathematical models and hydrological simulations are used to estimate these parameters. However, the specific calculation for a particular scenario requires detailed data and analysis of the local conditions, including rainfall patterns, topography, and urbanization extent.
In summary, urbanization increases the volume of water in and decreases the lag time of a flood by reducing infiltration and increasing surface runoff. The precise calculation depends on various factors and requires specific data for the given area.

What is the best description of the origin of the solar system?Would it have been possible for a large, Jupiter-like planet to form in the location of Mars?
In the early stages of the solar system's formation, a protoplanetary disk of gas and dust surrounded the young Sun. Within this disk, planets began to form through a process called accretion, where small particles collided and stuck together, gradually growing in size.
The location of a planet's formation is influenced by various factors, including the amount of material available and the temperature gradient in the protoplanetary disk. Jupiter, being a gas giant, formed further out from the Sun where the disk was cooler and contained more volatile elements.
On the other hand, Mars is a terrestrial planet and formed closer to the Sun where the disk was warmer and contained primarily rocky material.
Therefore, it would not have been possible for a Jupiter-like planet to form in the location of Mars due to the differences in the composition and conditions of the protoplanetary disk in those regions.
Which of the following observations does NOT provide information about the formation of the solar system?
Among the provided options, the observation that "most of the planets orbit the Sun in the same plano" does not provide information about the formation of the solar system.
While it is a characteristic of the planetary orbits, it does not directly contribute to our understanding of how the solar system formed.
Other observations mentioned in the options, such as the distances of Jovian planets from the Sun, the direction of planetary orbits, and the rotation of planets on their axes, provide valuable insights into the formation and dynamics of the solar system.
What statement best describes the origin of the solar system?
The best description of the origin of the solar system is that "the solar system formed from the collapse of a spinning cloud." This statement refers to the nebular hypothesis, which suggests that the solar system originated from a rotating cloud of gas and dust known as the solar nebula.
Over time, the gravitational collapse of the nebula led to the formation of the Sun at its center, while the remaining material in the disk-shaped cloud coalesced to form the planets, moons, asteroids, and other celestial bodies within the solar system.
This hypothesis is supported by various lines of evidence, including observations of other star-forming regions and the composition and characteristics of the solar system objects.

which type of map or diagram would best indicate elevation of the land surface?
Answers
Answer: A topographic map or a contour map would best indicate the elevation of the land surface.
Explanation: Topographic maps or contour maps are specifically designed to represent the elevation and relief of the land surface. These maps use contour lines to depict changes in elevation. Contour lines connect points of equal elevation and provide a visual representation of the shape and features of the terrain.
Contour lines on a topographic map are typically labeled with the elevation value at certain intervals, allowing users to determine the elevation of specific locations. By closely examining the spacing and patterns of the contour lines, one can identify areas of steep slopes, valleys, ridges, and other landforms.
Additionally, topographic maps often include supplementary information such as spot heights, which provide precise elevation values at specific points, and color shading or hachures to enhance the visualization of elevation changes.
Overall, topographic maps and contour maps are widely used tools for understanding the elevation and topography of an area, making them the most suitable map or diagram type for indicating the elevation of the land surface.

Answers
Answer:
formation of accretionary disk, formation of planetesimals, differentiation, formation of Moon
Explanation:
Materials from the nebula that were not absorbed by the sun composed a flat CD-like disk of dust and gas, held in orbit by the gravity of the sun. This is known as the formation of accretionary disk. The planets then start out microscopic in the accretionary disk, and after collisions, these particles start to form planetesimals. Obviously, differentiation is a consequence (which means it comes after). Lastly, assuming this question supports the theory that the earth had a collision with a much larger planet, billions of years ago, the material that was, essentially, shot into space, for lack of a better phrase. This caused the formation of our Moon.

______ of hominoid history was spent on the african savanna plains as hunter-gatherers.
Answers
Over 99% of hominoid history was spent on the African savanna plains as hunter-gatherers.
The first hominoids evolved in Africa around 6 million years ago. These early hominoids were small, tree-dwelling creatures. Over time, some hominoids evolved to live on the ground.
These ground-dwelling hominoids were able to walk upright, which gave them an advantage over other animals. They were also able to use tools, which helped them to survive in the savanna.
Hominoids continued to evolve in Africa. Around 2.5 million years ago, the first humans evolved. Humans are a type of hominoid that is characterized by its large brain, bipedalism, and tool use. Humans spread out of Africa and eventually populated the entire world.
However, even after humans spread out of Africa, they continued to live as hunter-gatherers for thousands of years. It wasn't until the development of agriculture around 10,000 years ago that humans began to live in settled communities.
