The metamorphic textures in order of increasing metamorphic grade are:
Salty cleavageSchistocityBandingFoliated Textures of Metamorphic RocksThe texture of metamorphic rocks can be either granular or foliated. This time we will only discuss the foliation texture. Foliation is a collection of planar minerals, or concentrations of minerals, especially planar structures resulting from the flattening of mineral grains, such as mica.
Most metamorphic rocks are formed due to the influence of stress in a certain direction. Therefore, we can observe a striking directional texture. Foliation itself can appear subtle or obvious depending on the degree of metamorphism.
As temperature and pressure increase, a foliated texture develops in the following sequence.
Slaty Cleavage is the pervasive parallel foliation of fine-grained platy minerals such as chlorite in a direction perpendicular to the direction of maximum stress. This process produces slate and phyllite.Schistosity is the layering in coarse-grained crystalline rocks due to the parallel arrangement of platy mineral grains such as biotite, muscovite, quartz, feldspar, plus various other minerals such as garnet, kyanite, and sillimanite.Banding is the inner layer of rock in which bands or lenses of granular minerals such as quartz and feldspar alternate with bands or lenses in which platy minerals (mica) elongate and predominate.Learn more about The Highest Metamorphic Grade here: brainly.com/question/13221649

channel beds erode faster than channel sides in ____ streams and rivers. - highly turbukent - high velocity - high gradient.
Channel beds erode faster than channel sides in high velocity streams and rivers. A smooth channel has less friction than a rocky or boulder strewn channel, so it moves faster.
The velocity of a stream is thus greatest in a narrow, deep, smooth, semicircular channel. Flow velocity. The velocity of a stream is the rate at which it flows. In high velocity streams and rivers, channel beds erode faster than channel sides. Because of the steep slope, a mountain stream moves quickly. This results in a lot of erosion and little deposition. Rapidly falling water digs into the stream bed, making it deeper.

describe the airflow around a low-pressure center (cyclone) and a high-pressure center (anticyclone) and the weather associated with each.
A cyclone is a large scale air mass that rotates around a low-pressure center. The rotation is caused by the Coriolis force, which is stronger at the poles than at the equator. The cyclone's rotational energy is transferred to the atmosphere, which causes the air to rise. This rising air causes the pressure at the center of the cyclone to drop, which causes the wind to speed up. The cyclone's rotational energy is also transferred to the water, which causes the waves to grow larger. The cyclone's wind and waves can cause extensive damage to coastal areas.
The anticyclone is the opposite of the cyclone. It is a large scale air mass that rotates around a high-pressure center. The anticyclone's rotational energy is transferred to the atmosphere, which causes the air to sink. This sinking air causes the pressure at the center of the anticyclone to rise, which causes the wind to speed up. The anticyclone's rotational energy is also transferred to the water, which causes the waves to grow smaller. The anticyclone's wind and waves can cause extensive damage to coastal areas.

Roads built by humans enable water to soak into the earth is not true about groundwater and all other statements are true about groundwater
What is Groundwater?
Water that is found underground in saturated regions beneath the surface of the land is known as groundwater. The water table is the term used to describe the top layer of the saturated zone. Groundwater does not form underground rivers. It fills the pores and fractures in underground materials such as sand, gravel, and other rock, much the same way that water fills a sponge.
Our rivers run more freely because of groundwater. Nearly 50% of Americans utilize groundwater for drinking water, but its primary applications are in crop irrigation and agricultural production.

Approximately once every hundred and fifty years locked segments of the san andreas fault break, resulting in major earthquakes .
What is meant by Earthquakes ?
An earthquake is the shaking of the Earth's surface caused by a rapid release of energy in the Earth's lithosphere, which generates seismic waves. It is also referred to as a quake, tremor, or temblor. Earthquakes can range in strength from those that are so little that no one can feel them to those that are powerful enough to throw things and people into the air, destroy vital infrastructure, and devastate entire cities.
The number, kind, and size of earthquakes that occur in a region during a specific time period is known as its seismic activity. The average rate of seismic energy release per unit volume is what is known as seismicity at a certain region on Earth. Tremors, which are not earthquakes, are also referred to as seismic rumbling.

Life on Earth is protected by the ozone layer. A form of radiation known as ultraviolet light, or UV light, that can permeate organisms' protective layers like the epidermis and harm Plasmid dna in plants and animals, is well-trapped by ozone.

Changes in climate affect the sea level by:
About 90 percent of the heat generated by increased emissions has been absorbed the sea level. As the extra heat and energy warm the ocean, the change in temperature results in unprecedented cascading effects, such as ice melting, sea level rise, marine heatwaves, and ocean acidification.
Influence of sea level rise on human populations:
Due to flooding and erosion, human populations and other species are displaced. Coastal flooding increases groundwater salinity, which diminishes freshwater quality and availability and soil quality. This has repercussions for agricultural produce and cattle. The prevalence of coastal ecosystems.
Population growth and rising consumption tend to increase emissions of greenhouse gases that alter the climate.
