No, a tornado is accompanied by such a cloud. Hurricanes generally have ordinary-looking storm clouds if you can see them through the rain.
The sign for lava in American Sign Language (ASL) involves fingerspelling "L-A-V-A," accompanied by a downward, flowing motion to represent the movement of lava.
The best way to extend a drain pipe for proper water drainage in a home is to use a PVC pipe extension. Cut the existing pipe, attach the extension with PVC glue, and ensure it slopes downward to allow water to flow away from the house.
Normal faults accommodate extension of Earth's crust through the hanging wall moving downward relative to the footwall. The hanging wall is pulled down due to tensional forces, resulting in the crust being stretched and thinned.
This kind of fault is called a normal fault and is usually a sign of crustal extension.
This kind of fault is called a normal fault and is usually a sign of crustal extension.
During flexion, the shoulder joint allows the arm to move forward and upward, increasing the range of motion. During extension, the shoulder joint allows the arm to move backward and downward, decreasing the range of motion.
As an object falls, its potential energy (PE) decreases due to the force of gravity pulling it downward. This decrease in PE is accompanied by an increase in kinetic energy (KE) as the object gains speed from its downward motion. Thus, energy is converted from PE to KE as the object falls.

Foot flexion refers to the bending of the foot downward, while foot extension refers to the movement of the foot upward. Flexion has a greater range of motion compared to extension, allowing for more movement in activities like walking and running. However, excessive flexion or extension can lead to strain or injury in the foot, affecting overall foot health. It is important to maintain a balance between flexion and extension to prevent issues such as plantar fasciitis or Achilles tendonitis.
Yes, the extension of the foot where the forepart is pushed down is known as plantar flexion. This movement occurs at the ankle joint, allowing the toes to point downward, similar to pressing a gas pedal. It is commonly used in activities like walking, running, and jumping.
Shoulder flexion involves raising the arm forward and upward, while shoulder extension involves moving the arm backward and downward. Shoulder flexion typically has a greater range of motion compared to extension. Different muscles are activated during each movement, with shoulder flexion primarily involving the anterior deltoid and shoulder extension primarily involving the latissimus dorsi and teres major muscles.
The continental shelf is an extension of the cotton, only beneath water. The continental slope begins beyond the shelf and slopes downward.
