Whatdoes the theory of plate tectonics have that Wegener's hypothesis of continental drift did not have?
Answer: The theory of plate tectonics has a mechanism for explaining how the continents move, while Wegener's hypothesis of continental drift did not.
Explanation: In the early 20th century, Alfred Wegener proposed the hypothesis of continental drift, which suggested that the continents were once joined together in a single landmass called Pangaea, and had slowly drifted apart over millions of years. However, Wegener did not have a mechanism to explain how the continents moved.
In the 1960s, the theory of plate tectonics was developed, and it provided a mechanism for understanding how the continents move. The theory of plate tectonics suggests that the Earth's lithosphere (which includes the crust and the uppermost part of the mantle) is divided into a series of plates that move relative to each other. The motions of the plates are driven by convection currents in the mantle.
At the boundaries where the plates meet, different phenomena occur. At divergent boundaries (such as the Mid-Atlantic Ridge), new crust is formed as magma rises to the surface and hardens, pushing the plates apart. At convergent boundaries (such as the Andes Mountains), plates collide and one is forced under the other (in a process called subduction). At transform boundaries (such as the San Andreas Fault), plates slide past each other.
The theory of plate tectonics thus provides a mechanism for explaining how the continents move over time. As new crust is formed at divergent boundaries and old crust is destroyed at subduction zones, the plates move apart and the continents drift. This explains why the continents are moving today and have been moving over geological time scales, and how they have been in different positions in the past.
Overall, while Wegener's hypothesis of continental drift was a significant step in understanding the evolution of the Earth's continents, it was the theory of plate tectonics that provided the more complete and explanatory picture, by proposing a mechanism for how the continents move.

1 pts as erosion strips off the tops of mountains, the mountains will "bob" upward. this is an example of
This phenomenon is known as isostatic rebound. Isostatic rebound occurs when the pressure exerted by the overlying material is relieved, usually caused by erosion. It is believed that this process occurs due to the removal of material, such as ice or sediment, from the upper layers of the mountain.
As this material is removed, the weight of the mountain decreases, causing the mountain to slowly “bob” upwards. This process is gradual and can take hundreds or even thousands of years to fully complete. Isostatic rebound plays an important role in the overall geology of a region, and can often result in dramatic landscape changes. For example, recently glaciated areas are often characterized by low relief, whereas regions that have experienced isostatic rebound often have steep terrain.

Further west from the deep U.S. trough, Eastern Alaska, as well as Yukon and British Columbia, Canada, were being impacted by a ridge.
A ridge of high pressure is impacting Eastern Alaska, Yukon and British Columbia in Canada, further west from the deep U.S. trough. A ridge of high pressure is an area of high atmospheric pressure, which is associated with fair weather, light winds and generally pleasant conditions. This ridge is formed when two air masses move away from each other, causing the air pressure in the area to increase. A ridge is typically indicated on a weather map by a line of red L's. The L's are placed on the map in the direction of the wind flow around the ridge, with the point of the L representing the area of highest atmospheric pressure.
The increased atmospheric pressure caused by the ridge produces lighter winds and warmer temperatures. The warmer temperatures and decreased wind speeds generally lead to more stable weather conditions and less precipitation. The ridge can also bring dry and sunny conditions, as well as a decrease in storm activity. These effects can be felt further downwind of the ridge, making it a welcomed feature in many areas.
In contrast, a trough is typically associated with low-pressure areas that produce wet, stormy weather conditions, as well as cool temperatures. This is because the low-pressure system promotes the formation of clouds and precipitation, which can reduce the amount of solar radiation that reaches the Earth's surface.

chemical sedimentary rocks are classified (named) based on the . group of answer choices grain sizes of the detrital particles degree of compaction and lithification colors of the cementing minerals mineral composition
Chemical sedimentary rocks are classified based on the mineral composition of the rock.
This classification is based on the minerals that make up the rock, as the minerals provide clues to the environment of deposition. The mineral composition of the rock is determined by the grain sizes of the detrital particles, degree of compaction and lithification, and colors of the cementing minerals.
Grain size is an important factor in determining the mineral composition of a rock. Detrital particles that make up the rock will range from fine-grained (clay-sized particles) to coarse-grained (pebble-sized particles).
Coarse-grained particles are more likely to form mineral grains such as quartz, feldspar, and mica, while finer-grained particles are more likely to form clays.
The degree of compaction and lithification are also important in determining the mineral composition of a rock. Compaction is the process of squeezing and rearranging particles together and lithification is the process of changing loose sediment into solid rock.

which term describes a soil that remails in place after having formed by weathering of the underlying bedrock? residual relict transformational transported
The term that describes soil that remains in place after having formed by weathering of the underlying bedrock is residual soil.
What is residual soil?
Residual soil, also known as residuum, is soil that forms from the weathering of bedrock that has remained in place. This soil is formed by in situ weathering and usually remains where it is formed. The weathering processes cause the bedrock to disintegrate into small particles, resulting in the formation of residual soil.
Residual soils are usually found on slopes and hilltops, where weathering is highest, and are often composed of coarse particles due to the intense weathering that occurs. They are generally thick and can be of varying depths depending on the bedrock they have formed from. The soil is typically rocky and nutrient-poor, which limits plant growth. Residual soils are classified as 4th-order soils according to the Soil Taxonomy. The Soil Taxonomy ranks soils into 12 orders based on their characteristics.

based on the distribution of magnetic anomalies, where is the oldest oceanic crust found? the youngest? what are their ages?
The oldest oceanic crust is found in the central Pacific Ocean and the youngest oceanic crust is found along the Mid-Atlantic Ridge. The oldest oceanic crust is about 180 million years old and the youngest oceanic crust is about 3 million years old.
The distribution of magnetic anomalies helps geologists identify the age of the oceanic crust. Magnetic anomalies are created when new oceanic crust is formed due to volcanic activity and tectonic plate movement. The magnetism of the oceanic crust is usually aligned with the Earth's magnetic field when it is first formed. As the Earth's magnetic field reverses, the magnetism of the oceanic crust is "frozen in time" and helps scientists measure the age of the crust.
The oldest oceanic crust is found in the central Pacific Ocean because it has been around the longest and hasn't moved much due to tectonic plate movement. The youngest oceanic crust is found along the Mid-Atlantic Ridge because this is where new oceanic crust is constantly being formed due to tectonic plate movement and volcanic activity.
By studying the distribution of magnetic anomalies, scientists can accurately measure the age of the oceanic crust and identify where the oldest and youngest crust can be found.
