The Strait of Hormuz is a Choke point that is used to monitor exports and imports leaving in the Middle East
Answer:
1- Option (C)
2- TRUE
3- FALSE
Explanation:
Joints are the type of fracture that splits the rock into two parts thereby the blocks move away from one another. They are formed due to the tensional force. Whereas, the fault, in simple terms is defined as the cracks or fractures present in the crust of the earth. They are formed by both tensional as well as compressional forces. They differ from one another in terms of displacement. In a fault, the relative displacement between the blocks is more than in the case of joints.
According to the law of cross-cutting relationships, geological features such as faults, igneous intrusions, that cuts across the sedimentary layers on earth are younger than those sedimentary rocks.
A neutron is a neutral particle as it does not carry any kind of electric charge. So, the addition or elimination of neutron from the nucleus does not affect the electric charge of the nucleus. But it can cause changes in the mass within the nucleus. Isotopes originate due to the addition or removal of neutrons from a nucleus.
Hence, the correct answers are given above.
Answer:
The effects of tropical cyclones include heavy rain, strong wind, large storm surges near landfall, and tornadoes. The destruction from a tropical cyclone, such as a hurricane or tropical storm, depends mainly on its intensity, its size, and its location. Tropical cyclones remove forest canopy as well as change the landscape near coastal areas, by moving and reshaping sand dunes and causing extensive erosion along the coast. Even well inland, heavy rainfall can lead to landslides in mountainous areas. Their effects can be sensed over time by studying the concentration of the Oxygen-18 isotope within caves.
Environment
After the cyclone has passed, devastation often continues. Fallen trees can block roads and delay rescues, with medical supplies, or slow the repairs to electrical lines, telephone towers or water pipes, which could put other lives at risk for days or months. Stagnant water can cause the spread of disease, and transportation or communication infrastructure may have been destroyed, hampering clean-up and rescue efforts. Nearly 2 million people have died globally due to tropical cyclones. Despite their devastating effects, tropical cyclones are also beneficial, by potentially bringing rain to dry areas and moving heat from the tropics poleward. Out at sea, ships take advantage of their known characteristics by navigating through their weaker, western half.
Hazards are often characterized as primary, secondary or tertiary. A primary hazard involves destructive winds, debris and storm surge. Secondary hazards include flooding and fires. Tertiary hazards include spikes in prices of food and other necessities, as well as long term hazards like water-borne diseases.
