chemical weathering is the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.
Chemical weather is when something non natural does something to the eviroment. Example: Acid rain melts away rock.
That type of stuff.
What kind of fault indicates that crust has been pulled apart?
a.reverse
b.strike-slip
c.normal
d.all of the above
I believe the answer is A
Answer:
d.all of the above
Explanation:
Geological fault is the rupture or splitting of a block of rocks or narrow bands of the surface that is responsible for the displacement of its parts. The accumulation of energy and its eventual release in geological fault zones is one of the factors responsible for the occurrence of earthquakes.
The types of geological fault vary according to the criteria used in their classification. In the present approach, they are typified in three different forms: normal, reverse, and transcurrent.
In the normal type fault, the split occurs when a block “descends” or lowers from the fault surface. This occurs when the pressure exerted on the region causes a negative tension.In reverse-type failure, splitting occurs when a block “rises” in relation to the fault, raising its surface. This happens when tectonism causes a tension responsible for compressing the space occupied by the rock layers.In the transcurrent fault, also called horizontal fault, there is a parallel movement between the two blocks, which can be caused by inverse vectors of horizontal forces applied on each rock segment.How will a short-term environmental change most likely affect organisms within an ecosystem?

A. It will lead to some deaths.
B. It will lead to speciation.
C.It will lead to adaptation.
D. It will lead to forced migration.
E.It will lead to changes in behavior.
Answer:
A. It will lead to some deaths.
D. It will lead to forced migration.
E.It will lead to changes in behavior.
Explanation:
More than 60% of the resources and services provided by the planet's ecosystems are degraded, and the consequences of this destruction could worsen significantly over the next 50 years, warns an international study published in 2015. Freshwater, fisheries, and air and water regulation Water, regional climates, natural disasters and pests are the most endangered natural resources and services, says the Millennium Ecosystem Assessment, prepared by 1,300 scientists from 95 countries. Degradation of 15 of the 24 ecosystems studied increases the likelihood of abrupt changes that can severely affect the well-being of all biodiversity on the planet, such as the emergence of new diseases, sudden deterioration in water quality, the collapse of fishing grounds and changes in regional climates.
The extinction rates of animal and plant species are increasing on an unprecedented scale. The average abundance of native species in most major terrestrial habitats has fallen by at least 20%, mostly since 1900. More than 40% of amphibian species, almost 33% of corals and more than one third of all mammals are threatened. .
Answer:
-It will lead to some deaths.
-It will lead to forced migration.
-It will lead to changes in behavior.

What would happen if plate motions were reversed?
A. A volcanic arc would form
B. New, younger mountains would form
C. A continental rift would form
D. An oceanic trench would form offshore
If plate motions were reversed, a continental rift would form. Thus, Option (C) is correct.
A continental rift is a process where a continent splits apart, resulting in the formation of a new ocean basin. This occurs when the lithospheric plates move away from each other, leading to the thinning and eventual breakage of the continental crust.
Reversing plate motions would cause the plates to converge instead of diverge, inhibiting the creation of a new ocean basin. Instead, the compressional forces generated by the convergence would give rise to mountain building.
Thus, Option (C) is the correct choice for the scenario where plate motions are reversed, as it accurately reflects the consequences of such a change.

When rocks bend what forms, when rocks break, what forms? A.) folds; faults B.) faults;folds
I'm pretty sure it's A... If its wrong let me know.
ANSWER:
Folds in rocks form when the rock bends. Meanwhile, faults form when the rock breaks. Various factors such as temperature, strain, confining pressure, and composition of the rock play a part in bending or breaking of the rocks.EXPLANATION:
Folds and faults are two recognizable geological structures which are created due to the deformation of the rocks due to various factors. These structures in rocks arise due to the pressure and stress in the tectonic plates and the rocks.___ rock forms from the crystallization of magma or lava
A. Igneous
B. Sedimentary
C. Metamorphic
A - Igneous
Sedimentary rocks are formed through sediments while metamorphic rocks are formed through compression of great pressure and heat.
Igneous rocks are known for forming from lava or magma.

Weather patterns during a La Niña cause less rainfall than normal along the southeastern coast of the United States. However, above-average rainfall occurs in Australia. Which event is most likely to occur during this La Niña? A.
Plants will die in Australia due to an increase in intense sunlight.
B. An earthquake will cause damage to buildings and roads in Australia.
C. A drought will cause rivers to run low along the southeastern coast of the United States.
D.Animals along the southeastern coast of the United States will lose habitat due to flooding.
the answer is NOT D i think the answer is C
Answer:
C. A drought will cause rivers to run low along the southeastern coast of the United States.

The La Nina is an oceanic atmospheric phenomenon and is a phenomenon that occurs as a colder country part of the El Nino Its combined as the southern oscillation system of the pacific ocean.

Katrina wanted to find out more about Wegener’s hypothesis because it didn’t explain how continental drift took place. Explain how scientists discovered the mechanism for the continents moving.
Answer and Explanation:
The mechanism which is responsible for moving the plates that bring change in the position of the continents is the convection in the asthenosphere.
Henry Hess, a geologist and an American Navy officer in the World War II, discovered that the sea floor and the the Mid Atlantic Ridge is spreading which helped the the scientists in studying and understanding the mechanism of how the plates move.
The theory of plate tectonics synthesizes these observations and provides a comprehensive model for the movement of Earth's lithospheric plates. It explains not only how continents move but also many other geological phenomena, such as mountain building, earthquakes, and volcanic activity.
Katrina's curiosity about Wegener's hypothesis is understandable since Alfred Wegener, who proposed the theory of continental drift in 1912, did not provide a convincing mechanism for how the continents could move across the Earth's surface.
The mechanism for continental drift was later explained by the theory of plate tectonics, which was developed in the 1960s. This theory is supported by several key pieces of evidence:
1. Seafloor Spreading: The discovery of the mid-ocean ridge system and the process of seafloor spreading provided a mechanism for the creation of new oceanic crust. Magma from the Earth's mantle rises to the surface at mid-ocean ridges, creating new crust as tectonic plates move apart.
2. Paleomagnetism: Studies of the magnetic minerals in rocks from different locations and of different ages showed that the Earth's magnetic field periodically reverses.
3. Convection Currents in the Mantle: The movement of tectonic plates is driven by convection currents in the semi-fluid asthenosphere, which is located beneath the rigid lithosphere.
4. Earthquake and Volcano Distribution: The distribution of earthquakes and volcanoes along plate boundaries provided further evidence for the movement of plates. .
5. Continental Fit and Fossil Evidence: The jigsaw-like fit of the continents and the distribution of fossil plants and animals across continents that are now widely separated also support the idea that the continents were once joined together and have since drifted apart.
