" which graph best represents the percentage by mass of elements of earth's crust " ?
Answers
Answer: Graph 1
Explanation:
The Earth’s crust has minerals that are made up of different elements, most of them combined in compounds. Of those elements, oxygen takes 46.1% of the total mass, while there´s 28.2% of silicon and the other 25.7% includes the rest of the elements, which are aluminum, iron, calcium, sodium, potassium, magnesium, copper, uranium, gold, and silver.
The elements of the earth's crust are oxygen, silicon, iron, and aluminum that accounts for about 88% of the earth's crust and the remaining 90 elements make up 12% of the earth's crust.
Oxygen hare the largest mass of these elements. The O2 elements are 46%, silicon 28.2%, and others 25% hence the option one is correct.Learn more about the represents the percentage by mass.

Explanation:
Stages. The Saturn V consisted of three stages—the S-IC first stage, S-II second stage, and the S-IVB third stage—and the instrument unit. All three stages used liquid oxygen (LOX) as the oxidizer. The first stage used RP-1 for fuel, while the second and third stages used liquid hydrogen (LH2).

A. Resource . . . Physical
B. Physical . . . economic
C. Economical . . . Climatic
D. Physical . . .Climatic
Answers
Answer:
B: Physical & Economic
Explanation:
Physical water scarcity occurs when and where there is not enough water to meet both human demands and those of ecosystems to function effectively. Arid regions frequently suffer from physical water scarcity. It also occurs where water seems abundant but resources are over-committed.
Economic water scarcity is caused by a lack of investment in water infrastructure or insufficient human capacity to satisfy the demand of water in areas where the population cannot afford to use an adequate source of water.

after shocks are often less powerful than the main earth earthquake. explain why after shock can still cause more damage
Answers
Answer:
The aftershocks can cause more damage than the main earthquake because they last much longer.
Explanation:
The earthquakes are a natural hazard that can cause very big damage, but also a big loss to lives. The earthquakes occur when cracks occur in the crust and when the crust from above falls down to adjust it releases a lot of energy. This energy is manifested with strong vibrations that manage to spread around and affect very large areas.
The earthquakes have a main earthquake and aftershocks. The main earthquake occurs only once and the damage it can do depends on its strength. The aftershocks, on the other hand, are not as strong, but they can last for days, weeks, or even months, so by continuously shacking the ground for a long period of time they often manage to make much more damage than the main earthquakes themselves.
Answer:The aftershocks can cause more damage than the main earthquake because they last much longer.

(E) Population pyramids provide greater detail than stage of demographic transition alone.
How are population pyramids and demographic transition models related?The shape of the Stage 2 population pyramid of the demographic transition reflects the decline in mortality, particularly among the youngest age groups with high fertility. The population is growing rapidly but remains relatively young.
Population Pyramid has five levels: large volatility, fast expansion, slow expansion, small volatility, and spontaneous decline.

Which statement accurately compares the trends in atomic number and atomic mass in the periodic table?
The atomic number increases from left to right, while the atomic mass increases from right to left.
The atomic mass increases from left to right, while the atomic number increases from right to left.
Both the atomic mass and the atomic number increase from left to right.
Both the atomic mass and the atomic number increase from right to left.
Answers
Answer:
Both the atomic mass and the atomic number increase from left to right
Explanation:
On the periodic table, both atomic mass and atomic number increase from left to right.
The periodic table is a grouping of elements based on their atomic number. Atomic number is the number of protons in an atom. These are the positively charged particles.
From left to right, the number of protons increase and hence the atomic number.The atomic mass is made up of the number of protons and neutrons.
Since the number of protons increase left to right, the atomic mass will also increase.
So, atomic mass and the atomic number increase from left to right.

Explanation:
London City is located at approximately 51° N, 0°. Thus, option A is correct.
What is latitude?Lines of longitude span the whole expanse of Earth between the North Pole to the South Pole, whereas a location's latitude is what's north or south of the equator.
London is located in southeast England, about 50 miles farther upstream towards the River Thames' delta on the North Sea, on both sides of the river. Anyone visiting the capital of the UK might be perplexed to learn that the City of London nor London are two different places.
