1- What were some of the main gods and goddesses in egypt.
What are some main events of JohnCabot's life?
Some chemical weapons as tabun, sarin, soman are considered slow effect agents.
A burned down city, collapsed bridges, smashed cars, leveled houses, are some examples of physical destruction.
Some agents of weathering are heat from the sun, plant and animal activity, freeze-thaw cycles, abrasion from windblown ice or water carried material, chemical weathering from acidic solutions such as acidic rain, and hydrolysis. The four main weathers agents are wind, ice, gravity, and water.The agents of weathering include temperature, water, and gravity. Water causes the most weathering with ice, rain, and river movement causing stone to weather.

•Aeolian • •Biological weathering • •Exfoliation • •Thermal Expansion
The main agents for chemical weathering are water and weak acids formed in water, such as carbonic acid (H2CO3). These agents dissolve some rocks, loosen mineral grains, form clay mineral, and widen fractures.
Wind, Water, and Ice.
There are many causes of weathering. Some of the main causes of weathering are:Thermal stressFrost weatheringOcean wavesPressure releaseSalt-crystal growthBiological effects
There are two types of weathering: chemical and physical. Chemical weathering is said to occur when the chemical compounds of rocks are changed. Physical weathering happens due to wind, rain, or other natural occurrences.
Agents of chemical weathering depend on the climate and composition of the rock that is breaking down. Some Agents would include, water, oxygen, CO2, and acids. Temperature plays a significant role in chemical weathering. If it is warm and wet, the Chemical weathering process will increase. So, really it all depends.
The worst is air pollution and acid rain caused by air pollution. Water (rain) and wind also cause some weathering.
