Köppen climate types of Missouri. Missouri generally has a humid continental climate with cool, sometimes cold, winters and hot, humid, and wet summers. In the southern part of the state, particularly in the Bootheel, the climate becomes humid subtropical. Located in the interior United States, Missouri often experiences extreme temperatures.
Between the two zones is the Missouri Gravity Low, or MGL, a mass of low density granite including the Missouri batholith up to 370 miles long and 60 miles wide, identified in gravity surveys. Igneous activity ended around 1.3 billion years ago, with the intrusion of numerous dikes and sills into newly crystallized rhyolite and granite.
The geographic poles are defined by the points on the surface of Earth that are intersected by the axis of rotation. The pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an ...
The North magnetic pole is approximately 965 kilometres (600 mi) from the geographic North Pole. The pole drifts considerably each day, which results in a change of 5-60 km per year. The speed of the change was around 10 km/year for the majority of the 20th century, then increased in the 1990s to over 50 km/year, but slowed down slightly after ...
Kansas City is a Late Carboniferous geologic group and formation having various significant alternating beds of limestone and shale known for forming high bluffs in Missouri, Kansas, and neighboring states. This formation was named for the bluffs within Kansas City, Missouri. [3] Primary group outcrops are in northwest Missouri.
Shortly after the first geomagnetic polarity time scales were produced, scientists began exploring the possibility that reversals could be linked to extinction events. [17] Many such arguments were based on an apparent periodicity in the rate of reversals, but more careful analyses show that the reversal record is not periodic. [ 18 ]
The New Madrid seismic zone (NMSZ), sometimes called the New Madrid fault line (or fault zone or fault system), is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.
Following at a distance of years the first recorded exploration of the majority of the valley by the Lewis and Clark Expedition (1804–1806), there have been numerous attempts at preserving the natural habitats of the Missouri River Valley, spurred in its early days by concerns of duck hunters, for the Missouri basin lies across a major ...
