The most famous and outspoken of the early proponents of continental drift was ______________.
The most famous and outspoken of the early proponents of continental drift was Alfred Wegener.
Alfred Wegener was the most well-known and vocal of the early continental drift advocates. The idea of continental drift is that the Earth's continents have shifted relative to one another during geologic time, giving the impression that they have "drifted" across the ocean floor.
The science of plate tectonics, which examines how continents move as they travel on plates of the Earth's lithosphere, has absorbed the concept of continental drift. Abraham Ortelius made the initial suggestion in 1596 that continents may have "drifted." The Austrian geologist Otto Ampferer was a pioneer of the contemporary mobilizm viewpoint.

Describe the major features of the island as shown in your topographic map. For each feature, explain how
you know what it is from the map. Are there peaks? If so, how high are they? Are there valleys? If so, how
long are they and how deep are they compared to the surrounding sides? If present, how high are any cliffs
The topographic map shows an island with a valley in the middle and an oval perimeter.
What is a topographic map?A topographic map is a term to refer to a type of map that is characterized by showing the relief of the earth's surface, at a defined scale. Additionally, topographic maps are accompanied by contour lines, which allow reflecting the shape of the Earth's surface.
What characteristics does the topographic map have?The topographic map has two peaks, these can be distinguished because each parallel line that makes up the map represents a different height, therefore, it can be inferred that the two lines that form a figure similar to an oval are the peaks of two mountains. Additionally, with the help of the level curve we can establish that its height is a little more than 4cm.
Secondly, a valley is distinguished in the middle of the two mountains, this valley is 3cm high and about 1cm wide. Finally, it can be inferred that this map does not have cliffs because the relief curve is progressive, unlike the cliffs that are walls on the seashore.

What characteristic features in the geologic record are only present from a large impact?
The characteristic features in the geologic record are only present from a large impact are Ejecta blanket, Complex crater, Buried impact breccia, and Shocked quartz.
An impact crater's ejecta blanket is a typically symmetrical apron of ejecta that is heavily layered near the rim and thin to discontinuous at the blanket's outer border. However, the creation process does not end with excavation as meteorite craters get larger. The parabolic hole for such craters appears to be too enormous to maintain itself, and it collapses as a result, producing a variety of morphologies. The ultimate depression is referred to as a complex crater.
A sedimentary rock known as breccia is made up of large, angularly shattered pieces of minerals or rocks that are bound together by a fine-grained matrix. Shocked quartz is a kind of quartz with a unique microscopic structure from regular quartz. Quartz's crystalline structure deforms along internal planes at high pressure (but constrained temperature).

On geologic timescales, the most dangerous type of volcanic eruption for living things is from?
On geologic timescales, the most dangerous type of volcanic eruption for living things is from Stratovolcanoes
According to the U.S., stratovolcanoes are also known as composite volcanoes because they are composed of layers of the alternating lava flow, ash, and unmelted stone blocks. geographic survey. They may reach heights of 8,000 feet and are bigger than cinder cones (2,438 m). A network of vents leading from a magma reservoir below the surface forms stratovolcanoes.
They usually have steep concave sides that sweep together at the summit to form a relatively modest crater when they are inactive. The top of the cone-shaped form, which typically has a crater, is where the form slopes progressively upward and gets steeper (up to 35°). Although the volcanic rock types that characterize stratovolcanoes range from basalt to rhyolite, andesite predominates in most of them.

Mount everest, at 29028 feet, is the tallest mountain on earth. what is its height in kilometers?
Mount Everest, at 29028 feet, is the tallest mountain on earth with 8.848 kilometers in height.
A specific someone by the name of Andre Waugh said that Mount Everest was 29,002 feet tall in 1856. Trigonometric surveys and analysis served as the basis for this. The overall height, which was acknowledged in both China and Nepal, was 8,848 metres. For a long time, this was the accepted record. Things didn't start to change until the 9th of October 2005, when an official declaration was issued stating that Mount Everest was, in fact, 29,017.16 feet high. This totaled 8,844.43 meters.
Geologic uplift causes Everest to rise by 4 mm, or 0.1576 inches, per year. It is believed that the neighboring plate tectonics is causing the height to increase and the peak to move northeast.

which of the following techniques is least likely to improve your ability to detect a trend in a climate data set?
Focusing on local data is the technique is least likely to improve your ability to detect a trend in a climate data set.
Long-term changes in temperature and weather patterns are referred to as climate change. These changes may be organic, but since the 1800s, human activity has been the primary cause of climate change. This is primarily because burning fossil fuels, such as coal, oil, and gas, releases gases that trap heat. Climate analysis entails creating modeling capabilities to predict future climate changes as well as creating climate projections for both study and long-term planning. Understanding the functioning of the climate system or a specific component thereof is the goal of climate analysis. The results of ongoing analyses offer recommendations that guide the way to a more thorough understanding and advanced climate research.

Partial melting results in a magma that is nearer the ________ end of the compositional spectrum than the parent rock from which it was derived.
Partial melting results in a magma that is nearer the felsic end of the compositional spectrum than the parent rock from which it was derived.
Although there are many different types of rocks in the Earth's crust, they may all be divided into two main groups: mafic rocks and felsic rocks. The composition of these rocks varies, and typically, their formation from lava or magma depends on their location.
Felsic rock
The words "feldspar" and "silica," which are frequently found in the makeup of felsic rocks, are the ancestors of the phrase "felsic." Felsic refers to igneous rocks that crystallize from magma or lava and are enriched with ingredients that can produce quartz and feldspar.
Rocks that are felsic can usually be distinguished by their color, texture, and other physical characteristics. The majority of felsic igneous rocks are pale in color, however, their textures can differ significantly.

The size of countries has been distorted by the data, with net contributors of the capitals shrinking in size, and net recipients of capitals expanding in size.
A common method for displaying statistics on geography, such as epidemiology and population trends, is the use of cartograms. The primary concept is to skew a map by resizing its sections in accordance with a statistical parameter while yet maintaining the map's recognizability. We officially describe a family of cartogram drawing issues in this paper. We demonstrate that even straightforward versions are intractable in the general situation. Heuristics are required to resolve the issue because there are NP-complete viable versions. The quality of the produced drawings in previously recommended solutions is poor. The global form or contour of the input map must be preserved for a cartogram to be recognizable, a need that has hitherto gone unmet.
