Weathering is the process by which rocks, minerals, and other geological materials are broken down and altered over time due to exposure to the Earth's atmosphere and environmental factors.
Physical weathering, also known as mechanical weathering, involves the physical breakdown of rocks into smaller fragments without any change in their chemical composition. This process is primarily driven by mechanical forces such as temperature changes, freeze-thaw cycles, wind, water, and pressure.
Chemical weathering is the process in which rocks and minerals undergo chemical reactions that lead to their decomposition and alteration. This type of weathering involves the interaction of rocks with substances in the atmosphere, such as oxygen, water, carbon dioxide, and acids.

Answer: Chemical weathering decomposes or decays rocks and minerals. An example of this is water and limestone. Organic weathering happens when plant break up rocks. One the rock has been weakened and broken up it is ready for Erosion. This happens when rocks are picked up and move usually by water. Mechanical weathering breaks up rocks, this usually happens when water gets into cracks, freezes and expands the rock
Explanation:
c. trade war

d. customs war
b. trees
c. shrubs
d. algae
Succession is _______.
a. harmful to ecosystems
b. a natural recovery process
c. unnecessary for ecosystem recovery
d. a one-time event
Answer: 1. d. algae
Explanation:
A primitive community is the ecological community which is occupied with the low diversity of biological species. The species located in this community includes simple organisms. The algae is an example of species that is expected to be found in a primitive community.
Answer:2 b. a natural recovery process
Explanation:
An ecological succession is a change in the biotic community of an ecosystem with respect to changes occurring in the non-living environment in due coarse of time, until the ecosystem attains stability. Succession is a natural recovery because even if any kind of natural or human induced destruction occurs in a region which is capable of reducing the population of living beings and destroy the physical environment. Some precursors of life will renew the growth and abundance of living species and the changes occurring in the physical environment will support the growth.
