Asteroids that can hit the Earth are primarily in the asteroid belt between Mars and Jupiter. When an asteroid hits land, a massive amount of smoke and dust is thrown into the atmosphere. This prevents sunlight on Earth, along with severe temperature drops. When an asteroid hits the water, it causes a tsunami. Astroids striking on land or water can cause the global extinction of life.
When an asteroid hits the water, massive waves result.\
THE LAST 4 ASTEROID HITS ON EARTH:
1. 65 million years ago. (The dinosaurs went away).
2. 70.3 million years ago.
3. 145 million years ago.
4. 215 million years ago.
THE LAST 5 EXTINCTIONS OF LIFE ON EARTH:
1. Ordovician-Silurian Extinction: 440 million years ago.
2. Devonian Extinction: 365 million years ago.
3. Permian-.Triassic Extinction: 250 million years ago.
4. Jurassic Extinction: 210 million years ago.
5. Cretaceous-tertiary Extinction: 65 Million Years Ago.
6. THE 6TH EXTINCTION PHASE IS IN THE WORKS:
A receding of the Pre-Cambrian ice age caused a warmer climate and higher oxygenation in the seas. This environment was a host to explosive radiation of species in the ocean. Life at that time was only ordinary in the water. The land was barren and subject to erosion. The Cambrian explosion marked an extraordinary diversification of marine animals. This diversification of animals happened practically overnight. The Permian extinction occurred 299 to 251 million years ago. Less than 5 percent of the animal species in the seas survived. Trilobites went extinct about 251 million years ago when the dinosaur age started; fossils of complex skeletal parts from the pre-Cambrian period do not exist.
All skeletal marine invertebrate species appeared during the Cambrian explosion, except for Bryozoa with mineralized skeletons, which first appeared in the Early Ordovician.
Was the Cambrian explosion caused by an asteroid? The Cambrian explosion happened when environmental changes crossed critical thresholds. This led to the initial formation of the metazoan-dominated ecosystem. The Cambrian explosion happened more than 500 million years ago. It was when most of the major animal groups started to appear in the fossil record. Different life forms rapidly appeared in the seas.
The dinosaurs were the first complex animals to show up. The oxygen levels in the Earth’s oceans fell dramatically and wiped out many Cambrian species. The rising oxygen levels on Earth were necessary to permit animals to prosper.
When an asteroid hits the Earth, it causes the atmosphere to change. Dust and particles of debris from the collision find their way into the upper atmosphere and have the effect of blocking the sun’s rays. Insolation is reduced, and the climate cools because energy from the sun is reflected into space. Debris from the collision finds its way into the upper atmosphere and has the effect of blocking the sun’s rays. Insolation is reduced, and the climate cools because energy from the sun is reflected into space. The asteroid’s explosion acted as a temporary brake on the species’ evolution.
The clouds of dust blocked sunlight, which impaired most photosynthetic processes.
Marine biodiversity quadrupled in a few million years. The immense biodiversity happened 469 million years ago, In the Ordovician Period.
Intelligent agents can rapidly infuse large amounts of information into systems. Intelligent design provides a sufficient causal explanation for the origin of large amounts of data, of intelligent agents generating informational configurations of matter.
The intelligent design of a blueprint often precedes the assembly of parts in accord with a blueprint or preconceived design plan.
Intelligent agents produce material entities through a series of gradual modifications. Intelligent agents also can introduce complex technological systems into the world fully formed. Complex biological forms require large amounts of new genetic information that will appear abruptly in the fossil record, entirely created, and without similar precursors. Biological novelty commonly occurs in the fossil record suddenly, fully formed, and without similar precursors or evolutionary intermediates.
Many species remain virtually unchanged for millions of years, then suddenly disappear only to be replaced by a different but related form. Also, most major groups of animals appear abruptly in the fossil record, fully formed, with no prior fossil record—ditto for any transition forms.
