Which formation occurs when large quantities of magma begin to push through mantle of the Earth and into layers of the crust?
When large quantities of magma push through the Earth's mantle and into the crust, it can create a volcanic formation known as a volcanic hotspot or a volcanic arc. This process often leads to the formation of volcanoes, volcanic mountains, and lava flows on the Earth's surface.
How hailstorms are formed?
Hailstorms are formed when strong updrafts in thunderstorms carry raindrops into the cold upper atmosphere, where they freeze into ice pellets. These pellets are then repeatedly carried up and down by updrafts and downdrafts, which add more layers of ice and cause the hailstone to grow larger. When the hailstone becomes too heavy for the updrafts to support, it falls to the ground as hail.
What is concentric weathering?
Concentric weathering, also known as spheroidal weathering, is a type of physical weathering that occurs on rocks with uniform composition. It involves the gradual wearing away of outer layers of rock, resulting in the formation of onion-like layers or spheres on the surface of the rock. This type of weathering is commonly seen on boulders and large rock outcrops.
What is the process by which large sheets of loosened rock break away from an outcrop?
The process is called exfoliation, where outer layers of rock peel away due to pressure release as the rock is exposed at the surface. This can be caused by factors like temperature changes, erosion, or tectonic stresses, leading to the formation of large sheets of rock.
What role do large ion lithophile elements play in the formation of minerals and rocks?
Large ion lithophile elements, such as potassium and rubidium, play a significant role in the formation of minerals and rocks by influencing their chemical composition and stability. These elements are commonly incorporated into minerals during their formation, affecting their properties and behavior. Additionally, large ion lithophile elements can help geologists understand the processes that led to the formation of specific rocks and minerals.

Why balls of hail have layers?
Every hailstone begins to form as an ice nucleus, a small cluster of supercooled water droplets or clumps of snow. This center is called a graupel, and it may continue to accumulate ice, melt in the thundercloud and turn to rain, or be smashed apart by other graupels. If a bug, piece of bark, seed, or stick gets blown up into the storm cloud, it creates another possible nucleus for a hailstone.If the thunderstorm is cold and windy enough, this graupel will accumulate layers of ice the way a dipped candle accumulates layers of wax, through a process called accretion. Opaque, whitish layers form when icy droplets trap air bubbles and stick to the graupel. Clear layers have accreted large drops of supercooled water that freeze when they encounter the hailstone. Of course, much larger hailstones can be made when two smaller ones freeze together.Hail can accrete more layers when the hailstone blows up through layers of the thunderstorm. Even heavy hail will be kept aloft by strong enough updraughts. When the hail falls back through the storm due to gravity, it accretes even more layers, until it is so heavy it falls as precipitation. Hail forms in most tall, cumulonimbus storms that reach the colder upper atmosphere, but not all hail survives its trip once out of the thunderstorm.The size of hail, once fully formed, varies from pinheads to softballs. A few outer layers frequently melt when the hail mixes with other warmer precipitation such as snow and rain. The National Weather Service has official size categories for hail that are useful for gauging the damage they can cause to crops. How hail forms gives us a window into the interior of a thunderstorm, helping meteorologists study the evolution of storms as well.
What is between the batholith and the surface?
Between the batholith (large underground igneous rock formation) and the surface are various layers of rock, such as sedimentary or metamorphic rocks. These layers have accumulated over time to cover the batholith, and may also include soil, vegetation, and water before reaching the actual surface.
Can a hailstone really get as big as a baseball?
Yes, hailstones can grow as big as baseballs or even larger under the right conditions. This typically occurs in severe thunderstorms with strong updrafts that carry raindrops high into the cold upper atmosphere, where they freeze and accumulate more ice layers before falling as large hailstones.
What rock unit is distinct and laterally traceable?
A formation is a distinct rock unit that is laterally traceable over a large area. Formations are defined based on their distinctive lithology or fossil content, making them easily recognizable across different locations. This helps geologists correlate rock layers and map out the geology of a region.
What is a Flat deposits that cover large area?
they are called layers
What does the formation of erratics and kettle have in common?
They are both large
In stratified layers of layers of sedimentary what is it called when sediment settles on the bottom and the large grains settle on top?
Reverse Grading.

Do you have hail in 30 degrees Fahrenheit?
Yes, but it needs to be -40 degrees in the cloud's height to form it. it can hail when it's colder in the upper atmosphere. Hail can happen but the water droplets must stay in the cloud to get them supercooled, it melts when it hits the warmer region of the cloud. Anyway, Hailstone can go up and down in the storm to collect many ice and freezes much layers, this can be a large hailstone, if no longer ice stays aloft and falls to earth. attaching water drops to the ice and grows bigger and bigger enough to fall out. Hail considers the strong updrafts in these powerful thunderstorms. the stronger the storm, hail to fall.
