Answers

Answer 1

Answer:

40°

Explanation:

Given the following

∠AOC = 108°

∠AOB = 3x + 4°

∠BOC = 8x - 28

∠AOC = ∠AOB+∠BOC

108 = 3x+4+8x-28

108 = 11x-24

11x = 108+24

11x = 132

x = 132/11

x = 12

Next is to get ∠AOB. Recall that:

∠AOB = 3x+4

∠AOB = 3(12)+4

∠AOB = 36+4

∠AOB = 40°

Hence the measure of ∠AOB is 40°

Ocean surface currents Group of answer choices form counterclockwise circles in the northern hemisphere. flow smoothly, with few eddies. are found only in low- and mid-latitude areas. are influenced by the Earth's rotation.

Answers

Answer:

The correct answer is ''are influenced by the Earth's rotation.''

Explanation:

Ocean currents are the fastest and most constant part of ocean water. These flows are caused by the differences in temperature and salinity that the different seas and oceans of the world have, among other factors such as the rotation of the Earth. One of the forces that influences the movement of ocean currents is the rotational movement of planet Earth. Due to the effect called Coriolis force, it makes ocean waters rotate and flow in different directions according to their geographic location, for this reason, in the Equator, rotation has a lesser effect on the force of water movement. The further from the equator the waters are, the slower their movement will be, since the Earth rotates faster at the equator.

What is likely true about the tilt and location of a place if the weather is cold and snowy?

A. The axis is tilted away from the sun, and the location is in the mid-latitudes

B. The axis is tilted away from the sun, and the location is in the low-latitudes.

Answers

Answer is B. ( The acid is tilted away from the sun, and the location is in the low-latitudes). The more the Earth is away from the star, the more cold it gets because it receives less ultraviolet light and less likely to have an impact on the planet to make a certain place to be hot.

Since it receives less ultraviolet light and is less likely to have an impact on the globe to cause a particular spot to be hot, the Earth becomes colder the further it is from the star.

Thus, Option A is correct.

Of the choices below, select the one that accurately pairs the feature with the type of plate boundary at which it occurs. a. Accretionary prisms occur at divergent boundaries. b. Black smokers occur at consuming boundaries. c. Median valleys occur at transform boundaries. d. Trenches occur at subduction zones.

Answers

Answer:

d. Trenches occur at subduction zones.

Explanation:

A landform refers to a geomorphic or natural feature of the Earth's surface, which typically makes its terrain. Some examples of landforms on planet earth are mountain, plains, volcanoes, valley, hills and plateau.

Basically, the tectonic plates such as the oceanic and continental lithosphere interact in three (3) ways and these are; divergent, transform and convergent boundaries.

A convergent plate boundary can be defined as a boundary where two (2) plates move towards each other, usually, resulting in subduction or collision.

Simply stated, a subduction zone is an area where subduction occur.

Hence, it is a zone which represents the collision between the two (2) tectonic plates of planet Earth. Subduction zone occurs in countries such as Japan, Canada, Indonesia, Russia, Alaska, and around the Pacific Ocean.

Generally, subduction zones are responsible for high intensity earthquakes, volcanoes and tsunamis around the world.

As a result of subduction which causes a plate to be forced underneath the mantle, deep ocean trenches are formed such as the Mariana trench.

Answers

Answer:

c. the surface of the Earth is not smooth.

Explanation:

The reference spheroid does not represent a completely accurate picture of the Earth's gravity because "the surface of the Earth is not smooth."

This is based on the fact that mass is distributed unevenly within the planet. The greater a concentration of earth mass has a gravitational pull on the earth surface, thereby generating bumps around the globe, this situation including some other factors such as mass shifts inside the earth, shifting and altering the weight of the ocean and atmosphere, among others, affect the shape of the earth.

What is Galaxy?

A galaxy is a large collection of planets, celestial bodies, gas, and particles. Gravity keeps a galaxy together. A big black hole also resides in the center of our galaxy, the Milky Way.

A spiral galaxy termed a barred spiral universe has a star-focused central bar structure. In almost two-thirds of spiral galaxies, streaks are present.

Stars no more revolve in circular orbits when a large barrel arises instead, the bar has bent the stars' orbits, which is causing them to move into more circular orbits that pass close to the center of the galaxy.

two pieces of evidence which indicate that Paarl receives seasonal rainfall​

Answers

Explanation:

Climate change is a highly contentious topic in the modern world. There is much evidence to indicate that climatic shifts and extreme weather anomalies are taking place globally, in some places more than others. This paper presents the findings on research to determine whether shifts in seasonal rainfall patterns are indeed already visible in historical rainfall data in the Western Cape of South Africa. The paper aims to provide some baseline information which can stimulate further research in this field. Different analytical methods were formulated to investigate the relationships between daily rainfall indices over a set timescale. Data was collected from the South African Weather Service (SAWS) in order to accumulate 20 rainfall stations, each with at least 100 years of historical daily rainfall data. Statistical analysis, linear trend line distributions, time lag comparisons, cumulative distributions, moving average plots and autocorrelation relationships were applied to the data. The results of the analysis indicated that (1) the rainfall season undergoes fluctuations of wetter and drier years (approximately 20-year cycles), (2) the South Coast region exhibits a shift towards a longer rainfall season, and in contrast the Mediterranean region is shifting to a shorter rainfall season when linear trend lines were analysed, and (3) the moving average plots showed only isolated seasonal shifts at the boundary months.

D. In some areas of the world, there is enough water, but people do not have enough money to purchase or dig wells to access it.
E. Middle Eastern nations are among the most water-stressed countries in the world.

Answers

The statement that is not true about water use is that the amount of water used in developing countries is higher than the one in developed nations (option B)

Water use is a term to refer to the use that is given to this natural resource in human societies. In recent years this has been an important subject of study because it is a non-renewable resource, alternatives are being sought to promote its reuse, limit its waste and protect the sources in which it is produced.

Recent studies affirm that an inhabitant of a developed country consumes about 300 liters per day, while a person from a developing or underdeveloped country consumes about 25 liters per day. This means people in underdeveloped countries consumes less water.

Moreover, this is related to lack of access in remote areas, less waste and less manufacturing.

The coastal region is known for dry climates, cold nights and warm days. Thus, option 'A' (Coastal) is the correct option.

What is coastal climate?

The Coastal Plain has a pleasant climate with warm summers and cool, rarely freezing winters. Seasonal high precipitation, especially around the coast. Although highs in the mid-90s are not uncommon during the dog days of summer, the average yearly high temperature is roughly 77 degrees.

Although the Coastal Plain regularly receives below-freezing temperatures, year-round averages are in the 50s. Coastal regions are already under pressure from human activity, pollution, invasive species, and storms. Climate change threatens these places. Sea level rise may erode, inundate, and destroy coastal habitats and wetlands.

Oceans that are warmer and more acidic are likely to disturb marine and coastal ecosystems. The Coast Ranges' climate is characterized by moderate, rainy winters in the north and cold, dry summers.

Factors that contribute to nation building are good governance, a united and inclusive society and a flourishing business community.

Great nations with great and working economies we not built in a day, but took a number of concerted efforts over time between the government and its citizen to bring such nations into limelight and a beacon for others to follow. Recommendations for building up a great nation is centred on three factors viz:

1. Good governance

2. United and inclusive society

3. Cooperative business community.

These factors listed above are crucial because it produces a society that is united, can fend for itself and harmonized in tackling challenges that cuts across all sectors such as socioeconomic development, inequality etc...

With a prospering business community, especially in instances where small and medium scale businesses are allowed to flourish and develop to their full potentials, it is seen that the income inequality is quickly bridged, thus raising the standard of living of such countries and helping to eradicate poverty. This also boosts local manufacturing and subsequently international trade with other nations thus forming meaningful ties and allies.

A government vested on good and quality educational system not only creates a sense of belonging and national unity through school curriculum, but also to develop creative and progressive minds that get to form the very fabric of the nations' financial institutes, research institutes, civil workers, engineers, future teachers, businessmen and women etc.

A society that is more equal than it was yesterday, is always one step ahead towards the goal of nation building.
