What is the most powerful erosional agent? Water Erosion Water is the most important erosional agent and erodes most commonly as running water in streams. However, water in all its forms is erosional. Raindrops (especially in dry environments) create splash erosion that moves tiny particles of soil. What is the concept of graded stream? A […]
Will wind ever stop blowing?
Will wind ever stop blowing? Wind is the atmosphere trying to reach a pressure equilibrium. If the pressure is equalized, there will be no more wind. Which is rare on our planet as different areas are always heating and cooling. Hotter air is lower pressure and cooler air is higher pressure. Where on earth is […]
What are the three main characteristics of matter?
What are the three main characteristics of matter? Three States of Matter Matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed particles. Liquid matter is made of more loosely packed particles. Gaseous matter is composed of particles packed so loosely that it has neither […]
What are the two major types of seismic waves?
What are the two major types of seismic waves? There are two broad classes of seismic waves: body waves and surface waves. Body waves travel within the body of Earth. They include P, or primary, waves and S, or secondary, waves. What are the slowest seismic waves? The slowest waves, surface waves, arrive last. They […]

What happens if mass and velocity are doubled?
What happens if mass and velocity are doubled? Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum. What happens to the kinetic energy when the mass and velocity is […]
Which of the following is not considered a region of the spinal cord?
Which of the following is not considered a region of the spinal cord? The d. pelvic region is not considered a region of the spinal cord. Which cells form myelin in the spinal cord? Schwann cells make myelin in the peripheral nervous system (PNS: nerves) and oligodendrocytes in the central nervous system (CNS: brain and […]
What are the three main types of telescopes?
What are the three main types of telescopes? Types of Telescope. There are three main types of telescope. These are refracting telescopes, Newtonian telescopes and Schmidt-Cassegrain telescopes. Why do we use different types of telescope? Most objects give off several frequencies of energy simultaneously. Your body, for instance, glows in thermal infrared down to radio. […]
What is the basic unit of all matter on earth?
What is the basic unit of all matter on earth? Atoms are the basic units of matter and the defining structure of elements. The term “atom” comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided. What is the […]
