"Erratics" are large rocks that are not the same as the rock types found in the area and are deposited by the glaciers as they move or melt.
What are erratics?Stones and rocks that were carried by a glacier and then abandoned after the glacier melted are known as glacial erratics.
Some characteristics of erratics are-
The bedrock where the glacial erratic is deposited has a distinct lithology from the sort of rock that makes up the glacier erratic.A sandstone boulder moved by a glacier and placed on top of limestone bedrock would be an example of an erratic. Scientists can identify and locate the source outcrop of some erratics because they are made of a particular type of distinguishable rock. In order to recreate historical glacier flow directions, the timing of glacier retreat, and even the type of glacier flow, it is helpful to analyze glacial erratics.Large boulders, tiny stones, and pebbles can all be erratic. Every erratic is made of a unique sort of rock.To know more about the formation of erratics, here

After returning from his journey west, stephen h. long perpetuated the myth that the region between the missouri river and the rocky mountains was ______.
After returning from his journey west, stephen h. long perpetuated the myth that the region between the missouri river and the rocky mountains was unfit for cultivation.
Stephen Harriman Long (1784–1864) was an American military explorer best known for leading the 1820 expedition to what is now Colorado. On his journey map, he eminently called the arid Great Plains the "Great American Desert".
Even as late as 1823, Major Long of the Army Engineers noted that much of the land between the Missouri River and the Rocky Mountains was "almost wholly unfit for cultivation, and of course uninhabitable by a people depending on agriculture for their subsistence."
Today, the adaptation of technology to semi-arid areas and the development of new technologies have made the Great Plains one of the most productive agricultural regions in the world.

Geologist would use ice-core samples, rocks, and mud layers to find evidence of contaminates like radiation, chlorine, mercury, and coal exhaust.
Ice cores are ice cylinders that have been extracted from glaciers and ice sheets. They effectively serve as frozen time capsules that enable researchers to recreate former climates and the changes. Ice core layers are arranged according to years and seasons, with the newest ice at the top and the oldest at the bottom.
Geologist collects the ice cores all over the planet to research regional climate variability and to compare and contrast that variability with signals from the global climate. Ice cores, or samples taken from the ice, provide a history of our planet hundreds of thousands of years ago.

Southern California is famous for its wildfires, which are often exacerbated by the Santa Ana winds blowing through the canyons. What mass wasting event will later devastate the same fire-affected areas
The mass wasting event which will later devastate the same fire-affected areas is called Mudflows
Why do mudflows happen?
Mudflows occur when significant amounts of water collect to quickly erode soil on a steep slope. Mudslides happen when a lot of water builds up and quickly erodes the soil on a steep slope. As a result of heavy rain, for example, water seeps into the soil and separates the soil grains.
A muddy substance's starting point for flow is influenced by its particle size, water content, and topographical slope. In contrast to coarse sediment or a debris flow, shallower flows can transport fine-grained particles like mud or sand. A mud flow can start more easily when there is more water present (more precipitation or overland flow).
Coarser material may be swept up by a mud flow after it forms. Finer sediment and water that pools up behind the flowing front of the coarse-grained mudflow push the coarser silt that was taken up by the flow and often forms the front of a mudflow surge.

Xerophytic are the types of plants which grow in desert climates.
Xerophytes plants grow in areas with very little water in the soil and low amounts of rainfall. So, they are commonly found in deserts. Xerophytes such as cacti are capable of withstanding extended periods of dry conditions.
The Xerophytes plants grow in desert climates because they are able to withstand dry climates and also they have deep-spreading roots and capacity to store water which help them in the dry regions.
These Xerophytes plants have leaves with thorns which prevent loss of moisture. Also, their fleshy stems can store water. The xerophytic plants may also grow in salt marshes, frozen land area like the Arctic and Antarctic, or tropical forests.

What condition is necessary on earth to see eclipses of stars in binary star systems?
The line of sight from earth to the star system must be very close to the orbital plane of the stars to see eclipses of stars in binary star systems.
Each star in a double star system, also known as a binary star system, gravitationally pulls in the second star, which circles around the pair's centre of mass. Each star will be seen to eclipse the other once every orbital period if their orbital plane is edge-on to Earth. Eclipsing binary is the name for such a system.
It is also referred to as an eclipsing variable star because in an eclipsing binary system, the total amount of light fluctuates on a regular basis. When one of the two stars in an eclipsing binary is eclipsed, the light curve of the system experiences a deep minimum, and when the other star is eclipsed, the light curve experiences a shallower minimum.

The intertropical convergence zone may be found as far as ________ north of the equator in july.
The intertropical convergence zone may be found as far as 25° north of the equator in July.
What is real about the convergence zone between the tropics?
The Inter Tropical Convergence Zone, often known as the ITCZ, is a low-pressure area that rounds the Earth generally close to the equator and is the meeting point of the trade winds from the Northern and Southern Hemispheres. It is characterized by convective activity, which frequently results in intense thunderstorms over wide swaths of terrain.
How does the location of the intertropical convergence zone ITCZ change over time?
The position of the ITCZ varies seasonally because it tracks the sun. In the summertime of the Northern Hemisphere, it goes north, while in the wintertime, it moves south. As a result, the tropics' wet and dry seasons are caused by the ITCZ.

Updrafts dominate the cumulonimbus cloud during the ________ in the life cycle of an air mass thunderstorm.
Updrafts dominate the cumulonimbus cloud during the cumulus stage in the life cycle of an air mass thunderstorm.
Although first cumulus clouds frequently perish, their deaths are not in vain. In the same column as the initial cumulus, new cumulus clouds frequently form, benefiting from the water vapor from earlier-evaporating cloud particles.
Even if entrainment into the newly forming cumulus still continues, the air that is mixing into the cloud is more humid than before, which, as you may remember, reduces the possibility of net evaporation (and evaporational cooling).
A series of cumulus clouds can now develop and dissipate in a single column of air if there is an adequate supply of low-level moisture and persistent positively buoyant parcels throughout time.
Fair-weather cumulus eventually gives way to cumulus congestus, which is a towering cloud.
