What factors affect crater size and distance traveled by ejecta?
Factors affecting the appearance of impact crater ejecta are the geology of the target surface and the size and velocity of the impactor. Another factor, the angle of impact, will alter the pattern of ejecta coverage.
What factors affect the size of an impact crater questionnaire?
Factors affecting the appearance of impact craters and ejecta are: impactor size, impactor velocity, and target surface geology. two basic methods that form craters in nature are: the impact of a projectile on the surface and the collapse of the top of a volcano creating a crater called a caldera.
What are the effects of impact craters on living things and geological structures hit by a comet or asteroid?
When an impactor strikes the solid surface of a planet, a shock wave propagates from the site of impact. The shock wave fractures the rock and digs a large cavity (much larger than the impactor). The impact pulverizes the material – ejected – in all directions.
What factors determine how deep the meteor penetrates the ground, the size of the crater, and the distance traveled by the ejecta?
What I think can cause the crater size difference and 500 miles of ejecta and cause a meteor to sink deeper into the ground, it’s several factors; Namely, the mass, volume and density of the meteor, and how fast it is going before it hits the ground. The more the mass of the meteor increases, the heavier it is.
What factors affect the size of an impact crater?
The size and shape of a crater depends on several factors:
- the mass of the impacting object;
- the density of the impacting object;
- the speed of the impacting object; and.
- the geology (type of rock) of the surface the object hits.
How are impact craters formed?
The craters produced by the collision of a meteorite with the Earth (or another planet or moon) are called impact craters. The high velocity impact of a large meteorite compresses or forces down a large area of rock. The pressure pulverizes the rock. Most of the material falls around the rim of the newly formed crater.
What affects the size of an impact crater?
The size and shape of a crater depends on several factors: the mass of the impacting object; the density of the impacting object; the speed of the impacting object; and.
What are impact craters caused by?
The craters produced by the collision of a meteorite with the Earth (or another planet or moon) are called impact craters. The high velocity impact of a large meteorite compresses or forces down a large area of rock. The pressure pulverizes the rock.
How many meteors hit Earth each day?
An estimated 25 million meteoroids, micrometeoroids and other space junk enter the Earth’s atmosphere each day, resulting in approximately 15,000 tonnes of these materials entering the atmosphere each year.
How is the size of an impact crater determined?
Based on the experimental data, describe the appearance of an impact crater. 3. The size of a crater created during an impact depends not only on the mass and velocity of the impactor, but also on the amount of kinetic energy possessed by the impacting object.
What causes small impact craters on the Moon?
The size, mass, speed and angle of the falling object determine the size, shape and complexity of the resulting crater. Small, slow-moving objects have low impact energy and cause small craters.
How are irregular craters different from gradient craters?
Irregular Craters – Irregularly shaped craters or multiple impact craters formed at the same time. Oblong craters can be created by impacts striking the surface at a very low angle. Gradient craters – Craters that have eroded due to weathering, lava flows, impact, or downward movement of materials.
How are craters formed on the Earth’s surface?
Craters form when an object hits the surface of a planet, moon, or other object in space. Craters are also found here on Earth. The energy from the impact of an object such as a meteorite or asteroid is transferred to the surface it hits. The energy of the impact forces the surface it hits to move.
