Answer:
Divergent plate boundary
Explanation:
The African continent, the second largest in the world, is splitting in two parts. The African plate on which the African continent lies is actually after heavy geologic activity which causes it to split in two parts that are moving in opposite directions. This is a prime example of a divergent plate boundary. As the African plate gradually separates into the Nubian and Somali plates, they will open up a gap between them that will constantly grow. That gap will fill in with the ocean waters, splitting the two land masses with a natural barrier, as well as giving rise to a new sea, or maybe even an ocean over the course of millions of years.
What is underground formation containing groundwater?
Answer:
Groundwater is the water present beneath Earth's surface in soil pore spaces and in the fractures of rock formations. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water.
Underground water can be called creeks, lakes, streams and more
An underground formation that contains groundwater is known as an aquifer. Aquifers are usually rocky formations or soil where water collects and moves through, serving as vital sources of drinking water and irrigation.
Explanation:The underground formation containing groundwater is generally referred to as an aquifer. An aquifer is typically a rocky formation or soil in the earth's crust where water collects and moves through the horizontal and vertical spaces. These formations can range from sand and gravel to fractured bedrock like limestone or sandstone. Groundwater held in aquifers is an important source of drinking water, irrigation for agriculture, and it supports river and wetland ecosystems.

If you wanted to find a region rich in a particular type of rock, which type of map would you use?
Answer:
a geologic map
Explanation:
Answer:
To find a region rich in a particular type of rock, I would go for a geologic map.
Explanation:
A geologic map of a particular area specifically displays the terrain/landform in regard to the physical features of the area and their compositions. It not only indicates the availability of a specific feature but also shows its distribution of the feature over the area. The standard geologic maps have different colors and letters assigned to each of the different features for the convenience of the readers of the map. In most cases, geologic maps only serve geologists and prove of no use to the ones who have no knowledge of the discipline of geology.What is NOT likely to happen at a divergent boundary? A) Mountain formation B) Rift valley C) Seafloor spreading D) Volcano formation
A divergent boundary involves two tectonic plates moving apart, which can lead to phenomena like volcanic activity, rift valleys, and seafloor spreading. Mount formation, however, is more associated with convergent boundaries where plates move towards each other, leading to buckling and folding of the crust. Therefore, mountain formation is least likely to occur at a divergent boundary.
Explanation:A divergent boundary is a type of tectonic boundary where two plates move apart, often resulting in phenomena like seafloor spreading, rift valleys, and volcanic activity. This is due to the upwelling of molten rock from the mantle that fills the gap between the plates, forming new crust and often creating volcanic activity.
On the other hand, mountain formation is typically associated with convergent boundaries, where two plates move towards each other. This pressure causes the Earth's crust to buckle and fold, raising chunks of rock to form mountains. Examples of this include the formation of the Alps through the collision of the African and Eurasian plates.
Therefore, the process least likely to occur at a divergent boundary is A) Mountain formation. This is mainly because the key process in these areas is the pulling apart of tectonic plates, rather than them coming together which leads to mountain building.

The option that is NOT likely to happen at a divergent boundary is Mountain formation (A).
Divergent boundaries are locations where tectonic plates move away from one another, resulting in the formation of new crust.
Divergent boundaries commonly occur along mid-ocean ridges where seafloor spreading happens.
These boundaries often lead to the creation of rift valleys and can also result in volcanic activity due to magma rising up from below the Earth's surface.
Mountain formation, however, typically occurs at convergent boundaries where plates collide and push the Earth's crust upwards.
Therefore, the formation of mountains is not something you would expect at a divergent boundary.
Plant material that accumulates and hardens on the floor of a swamp is
known as peat. If a layer of sediments accumulates on top of the peat, its
weight, after thousands of years, can compress the peat to form coal. Which of the following types of coal probably
formed from the greatest pressure?
F Anthracite (the hardest coal)
G Bituminous coal (softer than anthracite)
H Subbituminous coal (softer than bituminous)
J Lignite (the softest coal)
Answer:
F Anthracite (the hardest coal)
Explanation:
Coal is a sedimentary rock that is formed from plant materials. These plant materials must have been trapped and compacted in an environment where they are not able decay. Such an environment is a swamp.
The first grade of coal that forms initially in such an environment is called PEAT. Peat is soft coal that still contains some plant materials. It has a high moisture content and the amount of carbon is still quite low.
With increasing pressure and compaction, PEAT grades into LIGNITE which has more carbon atoms in it. Lignite is more combustible although it is quite soft too. Lignite grades into SUB-BITUMINOUS coal and then BITUMIOUS coal.
The highest grade of coal is ANTHRACITE which is a hard coal. It has very little moisture content and rich carbon percentage in it. Anthracite yields more energy compared to other forms of coal. Anthracite is basically coal that forms at the greastest pressure. Beyond this pressure, a metamorphic transformation occurs and the coals changes to graphite.
Based on increasing pressure:
PEAT< LIGNITE< BITUMINOUS COAL < ANTHRACITE
