The meteorite impact theory proposes that the extinction of the dinosaurs and many other species around 65 million years ago was caused by a massive asteroid or comet colliding with Earth. This impact would have released large amounts of debris and caused environmental changes that led to the mass extinction event. This theory is supported by evidence such as the discovery of a layer of iridium-rich sediment found globally at the same geological level, indicating a significant impact event.

What was caused by called debris from asteroid impact on dry soil and rock?
Debris from an asteroid impact on dry soil and rock can cause a crater to form, as the impact can displace and eject material outward. The debris can also create shock waves that fracture and shatter the surrounding rock, leading to the formation of impact melt rocks. Additionally, the impact debris can spread out as ejecta, creating a layer of material around the impact site.
Change in a rock resulting from a meteorite?
A change in a rock resulting from a meteorite impact could include shock deformation, melting, and the presence of meteorite fragments or impact breccia. The rock may also exhibit unique mineralogical features due to the high temperatures and pressures involved in the impact event.
What about dry and wet impact value in aggregate test?
OBJECTIVE For determination of the aggregate impact value of coarse aggregate, which passes 12.5 mm. IS sieve and retained on 10 mm. IS sieve. Aggregate impact value test gives an indication of aggregate’s toughness property (i.e. property of a material to resist impact) Aggregate impact values are used to classify the stone aggregates with respect to toughness property as given below. The test equipment and the test procedure are quite simple and it determines the resistance to impact of stone aggregates simulating field condition. This test can be performed even at construction site or at stone quary, as the apparatus is simple and portable. Aggregate impact value test also gives an indirect indication of the strength characteristics of aggregate. Aggregate impact value of a sample also depends on the shape factors such as flakiness index and elongation index of the aggregates. It has been found that for majority of aggregates, the aggregate crushing value and aggregate impact values are numerically similar within close limits. For deciding the suitability of soft aggregates in base course construction, aggregate impact test is commonly used. A modified impact test is also often carried out in the case of soft aggregates to find the wet impact value after soaking the test sample in water. Maximum allowable aggregate impact value of aggregate in different types of pavement material / layers.
How does the direction of lightning affect its impact on the surrounding environment?
The direction of lightning can impact its impact on the surrounding environment by influencing where the energy is discharged. When lightning strikes the ground directly, it can cause more damage to the immediate area, such as starting fires or damaging structures. If lightning strikes nearby but not directly on the ground, the impact may be less severe.
What do you understand by dry and wet impact value?
For determination of the aggregate impact value of coarse aggregate, which passes 12.5 mm. IS sieve and retained on 10 mm.
