The process of melting that forms basaltic magma at divergent plate boundaries, such as the mid-ocean ridges is known as decompression melting.
What is Melting?Change of a solid into a liquid when heat is applied is known as melting.
Melting is also known as fusion.
Melting occurs when the internal energy of a solid increases.
What is basaltic magma?Basaltic magmas are formed by exceeding the melting point of the mantle. Basaltic lava is high in iron, magnesium, and calcium but low in potassium and sodium.
What is divergent plate boundaries?Divergent boundaries are spreading boundaries where new oceanic crust is created to fill in the space as the plates moves apart.
Most divergent boundaries are located along Mid-ocean ridges.
What is mid-ocean ridges?The mid-ocean ridge is two chains of mountains separated by a large depression that form at a spreading center.
What is decompression melting?Decompression melting involves the upward movement of earth's mostly-solid mantle.

As archaeologists excavate the strata or layers at a site, they establish a time sequence for the materials discovered in each layer based on the idea that the lower layers are older than the top layers. This idea is known as:____.
The concept whereby each layer is based on the idea that the lower layers are older than the top layers is known as superposition.
What is superposition?Superposition simply means the placement of a particular thing above or on top of another. In this case, the principle is used to determine whether one sedimentary rock is older than another.
It should be noted that sedimentary rocks form through the accumulation of layers in different environments like sea floor, lake or desert.
The sediment will then consolidate to become rock strata. The layers are deposited over a period of time in such a way that the layer on the top is younger than the layer on the bottom.

1: To be ADA compliant, wheelchair ramps require no more than a 4.8-degree slope for the ramp. How long in feet would a ramp need to be to reach a porch that is 36 inches above the ground.
2: If ramps can be no longer than 30 feet. Can just one ramp be built to reach the porch or would a landing and another ramp be needed to stay ADA compliant? Show and explain your work using mathematical language from this course.
The length of the ramp is about 35 feet.
What are trigonometric ratios?The trigonometric ratios are sine, cosine and tangent. These trigonometric ratios are used to solve the right angled triangle. A right angled triangle is one that has one of its angles as 90 degrees.
Now;
length of the ramp = 36/sin 4.8 degrees = 430 inches
If the ramps can not be more than 30 feet, just one ramp can not be used. This is because, the length of the ramp is 35 feet hence we need to build another ramp be needed to stay ADA compliant.

evaluate the impact of EL Nino conditions on the farming activities
El Niño is warming of the sea surface temperature of the Pacific Ocean. Extreme flooding,
drought, lack of potable water for livestock and domestic use, food insecurity and market
imbalance are associated with El Niño and La Niña in Ethiopia. Drought following El Niño
caused 50 to 90% crop failure, in the eastern parts of Ethiopia. El Niño episodes are detected
using different statistical indices such as Oceanic Nino Index (ONI), Agricultural Stress Index
System (ASIS) and the Southern Oscillation Index (SOI), with magnitude ranging from weak to
strong. Identifying the El Niño and La Niña seasons it is very important to adopt suitable
adaptation strategies, which can resolve and/or reduce the negative impacts. Early warning and
immediate support to the impacted areas have been carried out to minimize risks from El Niño
animal feed for livestock from other areas has been transported to the vulnerable areas. Planting
early maturing and drought resistant crops, supplementary irrigation, early waning information
on weather and climate have been exercised as climate change adaptation strategies, early
warning mechanisms by the government of Ethiopia. El Niño and La Niña are natural
phenomena; however, it is necessary to study the occurrence and distribution of El Niño and La
Niña episodes to enable early warning and identify suitable adaptation strategies and policy
implications in the country.
