How does the age of seafloor sediment change with increasing distance from the ocean ridge?

The sediments of the seafloor, the further they are from the ocean ridge, the older they are, and vice versa, the closer they are to the ocean ridge, the younger they are.

This redistribution of the age of the seafloor is due to the way the new crust forms. The new crust is forming where there's a divergent tectonic boundary between two oceanic plates. Because they leave a gap between them, the magma from the mantle manages to come to the surface. As it comes to the surface it starts to create the ocean ridge, which is essentially an underwater mountain range. Because the magma is constantly pushing and more and more material is coming out, the seafloor i pushed sideways constantly, thus the oldest sediments are the furthest, and the youngest are on the ocean ridge itself.

How did crops and the ability to grow them influence the inequality among different areas of the world

RSB [31]

Answer:

As explained below.

Explanation:

As the resources in the world are distributed unequally, the crops and the ability to grow them in specific environmental conditions such as near the river valleys, on the foothills of the mountains and near the flood plains differ worldwide as many places don't have enough sunlight,

many places is too warm or hot for there growth and other place are too cold or are locates at great heights. Variation thus exists in the cropping patterns and the cropping intensity as they need specific conditions as climate, weather, and soil properties.

Many of the earlier civilizations developed and prospered near the river valleys.

Organic materials (such as food scraps and yard waste) in landfills can decompose and produce landfill gas ( LFG ) over time. Ab

liubo4ka [24]

Based on the data provided:

LFG is used to produce electricity by using it as fuel in combustion turbines

the Puente Hills Landfill will emit 1.94 * 10¹⁰ cubic feet of LFG per year

9.7 * 10¹⁰ cubic feet of methane is prevented from entering the atmosphere.
the number of households that can have their total electricity needs provided by these landfills is 1,368,925 households.

<h3>What is the process of electricity generation from LFG?</h3>

Landfill gas, LFG can be used to generate electricity.

It contains 50% methane which is used as fuel for energy generation.

The process of generating electricity from LFG is as follows:

It is processed to produce methane.
The methane produced is combined with natural gas
The mixture is used as fuel for combustion turbines which then drives energy generation.

<h3>How much LFG is emitted at the Puente Hills Landfill per year?</h3>

From the data given:

ii) 1 million tons of landfill emits 432,000 cubic feet of LFG per day

123 million tons of landfill waste will emit 123000000 * 432000/1000000 cubic feet of LFG per day

The Puente Hills Landfill will emit 53136000 cubic feet of LFG per day

1 year = 365.25 days

Amount of LFG emitted in 1 year = 53136000 * 365.25 cubic feet of LFG per day

Amount of LFG emitted in 1 year = 1.94 * 10¹⁰ cubic feet of LFG per year

Therefore, the Puente Hills Landfill will emit 1.94 * 10¹⁰ cubic feet of LFG per year

<h3>What is the amount of methane prevented from entering the atmosphere by burning LFG to produce electricity at the Puente Hills Landfill over a 10-year period?</h3>

Volume of LFG produced in Puente Hills Landfill in 10 years is calculated below:

1.94 * 10¹⁰ cubic feet of LFG per year * 10 years = 1.94 * 10¹¹ cubic feet of LFG

Volume of methane in 1.94 * 10¹¹ cubic feet of LFG = 1.94 * 10¹¹ * 50% Volume of methane in 1.94 * 10¹¹ cubic feet of LFG = 9.7 * 10¹⁰ cubic feet of LFG

Therefore, 9.7 * 10¹⁰ cubic feet of methane is prevented from entering the atmosphere.

<h3>How many households can have their total electricity needs provided by these landfills in the United States?</h3>

Average yearly household electricity need = 30 kWh * 365.25 days

Average yearly household electricity need = 10957.5 kWh per year

Number of households = total electricity from LFG / average household electricity use per year

Number of households = 15000000000/10957.5

Number of households = 1,368,925 households

Therefore, the number of households that can have their total electricity needs provided by these landfills is 1,368,925 households.
