Answer:

In simple words, there existed no living on Earth for the first few million years since the environment was unsuitable for life. The original atmosphere of the Earth had a lot of water vapor but practically little oxygen. Volcanic activity blasted substances into the atmosphere such as nitrogen, carbon dioxide, hydrogen, and water vapor, but no pure oxygenation.

Answer:

Depth of lake

Explanation:

In simple words, The independent variable can be understood as the feature of a psychological investigation which is regulated or modified by investigators rather than by other factors. For instance, learning would have been the independent variable inside an investigation of the impact of studying on test results.

Thus, we can conclude that in the given case, depth of lake is the independent variable.

Answer:

Physical and human geography can be used to answer scientific questions such as:

"How to reduce deforestation related to environmental exploration?"

"How can the creation of borders interfere with social classes?"

"How to limit urban expansion?"

"How to reduce the problems caused by the rural exodus?"

Explanation:

Scientific issues are, most of the time, aimed at explaining and solving problems related to the physical environment and the way in which human beings are inserted in this space. It is because of these goals that physical and human geography is so important to the resolution of scientific issues, as they directly refer to the natural elements of terrestrial space and the interaction of this space with humanity. Thus, the junction between science, physical and human geography, can be useful to answer questions such as: political instability, population expansion and decrease, environmental issues, atmospheric phenomena, environmental exploration, among others.

Answer: Culture is found to affect economic performance through two channels; cultural traits that stimulate individual motivation, and traits that develop social capital in the population. The analysis controls for factors commonly recognized in the economic growth literature.

Answer:

These include land use change, land management, land degradation, soil sealing, and mining. The intensity of land use also has a great impact on soils. Soils are also subject to indirect impacts arising from human activity, such as acid deposition (for example, sulphur and nitrogen) and heavy metal pollution

The impact of human activities on soil are that some human activities have clear direct impacts.

These include land use change, land management, land degradation, soil sealing, and mining. The intensity of land use also has a great impact on soils.

Measures to conserve it include crop rotation, cover crops, conservation tillage and planted windbreaks

Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land.

It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable.

Natural hazards are excluded as a cause; however human activities can indirectly affect phenomena such as floods and bush fires.

It is estimated that up to 4% of the world's agricultural land is seriously degraded.

Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons. It reduces reliance on one set of nutrients, pest and weed pressure, and the probability of developing resistant pests and weeds.

A well-designed crop rotation can reduce the need for synthetic fertilizers and herbicides by better using ecosystem services from a diverse set of crops. Additionally, crop rotations can improve soil structure and organic matter, which reduces erosion and increases farm system resilience.

Answer:

135°

Explanation:

The measure of angle DCU is 135°.

This is because angle DCU is the combination of a square and a triangle.

One of the angles of the square is 90° + 45° which is the value of one of the angles of an isosceles triangle.

= 135°

Assuming Square ABCD and isosceles triangle BUC are drawn to create trapezoid AUCD. The measure of angle DCU is 135°.

ΔDCB=90°

ΔCBU=90°

Hence:

ΔBCU=ΔBUC

ΔBCU=(180°-90°)/2

ΔBCU=45°

Measure of  angle DCU:

ΔDCU=ΔDCB+ΔBCU

ΔDCU=90°+45°

ΔDCU=135°

Inconclusion the measure of angle DCU is 135°.

Answer:

The zone of convergence between sub-tropical and polar air masses, and where frequent traveling storms take place, is along the sub-polar latitudes.

Explanation:

Convergence zones are meteorological systems that have a strong impact on global climate quality. These systems are formed by the interaction of various meteorological events that occur between different latitudes.

The convergence zone, which encompasses the subtropical and polar air masses, has an influence on the amount of storms that occur frequently. This convergence zone is located along subpolar latitudes, being strongly influenced by the humidity found in this region.

Answer:

The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.

Explanation:

Answer: Red dwarfs

Explanation:

Red dwarfs are thought to be the coolest star out of the rest. They are also the smallest. Because they are so cool, their luminosity is low as well on account of the fact that relatively speaking, the fusion taking place on their surface is little.

Red dwarfs are the most numerous star in the universe and the most numerous in the Milky Way galaxy as well. We just can't see them with out naked eyes because of their low luminosities.

Answer:

- Continental climates are found in the Northern Hemisphere, but not the Southern Hemisphere.

- Climate and bioregion play a significant role in human settlement patterns.

- There is a strong correlation, and possibly even a causal relationship, between climate and bioregion.

Explanation:

- Climate plays an important role in the location of plants and animals that in turn are crucial components of a bioregion.

- The Population Density map shows human settlement patterns. These patterns are consistent with the patterns on both the climate and bioregion maps.

- The color associated with the continental climate is blue. The color blue is found in the Northern Hemisphere but not the Southern Hemisphere.

Answer:

El movimiento altersistema, y en ocasiones llamado como altermundismo o movimiento antiglobalización , es un amplio conjunto de movimientos sociales formado por activistas provenientes de distintas corrientes políticas, que a finales del siglo XX convergieron en la crítica social al proceso de globalización.

Existe cierta controversia sobre el término que define a este movimiento. Muchos de sus partidarios prefieren el término «altermundismo» o «alterglobalización», para evitar definirse por oposición, y porque el término «antiglobalización» daría una imagen imprecisa y negativa. El nombre altermundismo proviene precisamente del lema Otro mundo es posible, es un movimiento social heterogéneo compuesto por simpatizantes de muy variados perfiles, que proponen que la globalización y el desarrollo humano se basen en prioridad en los valores sociales y ambientales, en oposición a quienes los centran en el neoliberalismo económico, nacido en el Foro Social Mundial,[1] que cada año reúne a movimientos sociales de cientos de países del mundo.

El antiglobalismo acusa al actual proceso de globalización de beneficiar a las grandes multinacionales y a los países más ricos[2] acentuando la precarización del trabajo, y consolidando un modelo de desarrollo económico injusto e insostenible. También lo acusa de socavar la capacidad democrática de los Estados, entre otros aspectos negativos.[3][4][5]

Answer:

The rock texture with aligning parallel platy grains is to exhibit metamorphic foliation. Most metamorphic rocks have a platy or planar structure which is caused by the parallel alignment of micas and/or other flat mineral so this structure is called foliation. Metamorphic rocks can be foliated or non-foliated.
