At the end of seafloor spreading, where does the molten rock solidify? center of the ridge on the edge of the ridge under the new rock between the old rock layers.
The molten magma does solidifies at the center of the ridge at the seafloor spreading.
Seafloor spreading occurs when the Divergent plates continues to move apart, thus, creating a new seafloor.
Usually, a new crust (oceanic crust) are created by the Molten magma which pushes up from the mantle.
A very good example is the Mid-Atlantic Ridge
Therefore, the molten magma does solidifies at the center of the ridge at the seafloor spreading.

The best option that replaces the question mark in this question is option B. Negative effects of harvesting Brazil's rain forest.
The reason why this is the answer is because all of the bulleted options are the negative effects of land degradation.
Harvesting a rainforest means that there is a destruction of the habitat such as the felling of trees.
When this is done to the extreme, the land would be exposed leading to extreme weather conditions, decline in the productive strength of the land, sends the organisms and animals out of their natural habitats.

Humans evolved approximately 200,000 years ago. For what percent of geologic time have humans been present on Earth
Answer:
Our best guesses are that life began somewhere between 3.5 Billion and 3.8 Billion years ago
0.007%, to put things in perspective, while it may seem like a very long time ago, the origin of our kind, Homo sapiens, is just about 300 thousand years old, or 0.007% of the planet's 4.5 billion-year history.
What proportion of Earth's history is made up of humans?The Earth is thought to have formed 4.6 billion (4600 million) years ago, but by 3.9 billion years ago, only a few hundred thousand years after the molten globe solidified, the seas began to form, and the asteroid bombardment stopped, there is proof of the earliest primitive life.
Only about 500 million years ago did complex life start to emerge, which accounts for just 12% of Earth's history.
Depending on how you define it, current Homo sapiens are only between 200,000 and 50,000 years old.
The human lineage only separated from our most recent common ancestor roughly 5 million years ago, or less than half of 1% of that period.

Surface ocean currents are mostly driven by ______, whereas deep-ocean currents are driven by ______.
Answer:
The first blank is wind-driven
The second blank is density-driven currents
Explanation:
Surface ocean currents are mostly driven by wind whereas deep-ocean currents are driven by density differences. Therefore option A is correct.
What are Ocean currents?Ocean currents are basically when the water of the ocean flows horizontally. Basically, the ocean water flows in two directions first is vertically and second is horizontal, when the water flows vertically we called that is upwellings and downwellings on the other side when water flows horizontally we called it current.
There is a total of two types of current found in all the oceans, warm and Cold ocean currents. This classification is based on their origin, for example, the labrador is a cold ocean current because its origin is from a glacier but a gulf stream is a warm current because its origin is from a warm area.
There are many things that can affect the ocean current for example salinity variation, wind, density, earthquake, etc.
So in conclusion surface ocean currents are driven by the wind and deep ocean currents are driven by the Density differences

This diagram is an example of what type of stress?
Compression stress shortens and thickens
curling stress
mountain stress
tsunami stress
Answer: Mountain stress
Explanation: i did the same test
Mountain stress is the type of stress, as shown in the diagram. Hence, option C is correct.
What is meant by Mountain stress?When two or more convergent continental plates collide and lift one another up, mountains are created. Stresses from this uplift cause folds, reverse faults, and thrust faults, which enable the crust to ascend.
In geology, a stress that causes rocks to stretch in two distinct directions is referred to as "tension." The rocks get taller in a lateral direction and thinner in a vertical direction.
Before becoming a stable craton, mountain belts often form, harden, and erode over hundreds of millions of years. Its evolution can be divided into three phases: accumulation, orogeny, and uplift/block-faulting.
Thus, option C is correct.

what does it mean to say that a metamorphic rock is high grade?
High-grade metamorphism takes place at temperatures greater than 320oC and relatively high pressure. As grade of metamorphism increases, hydrous minerals become less hydrous, by losing H2O, and non-hydrous minerals become more common.
