Nov 03, 2014 · SPH4U1 - Dynamics Problems Set 9. The last cycle in a washing machine is always the spin cycle, during which the drum rotates at high speed about a vertical axis. Explain how the spin cycle removes water from clothing. 9 Inertia causes the water in your clothing to try to move in a straight line. If the drum in the washing machine were solid, it would apply a …

Coal. A fossil fuel consisting mainly of carbonized plant matter, found mainly in underground deposits and widely used as fuel. Fast Changes to Earth's Surface. Volcanos, earthquakes, floods. Slow Changes to Earth's Surface.

Earth's axis always points in the same direction relative to the stars. Earth's axis is tilted relative to its orbital plane. Earth orbits around the Sun, completing one orbit each year. Earth spins on its axis, completing one rotation each day.
The climate system is a complex exchange of energy and moisture from air, the oceans, organisms, soils and rock, and ice. Spheres. the geosphere, atmosphere, hydrosphere, cryosphere, and biosphere. Distinguish between weather and climate. Hint 1.
A proxy is a reasonable representation or estimate of the original. Proxy data are indirect evidence of past climates taken from natural recorders of climate variability. These data are necessary because direct measurements of past climates are limited to the recent past.
Seafloor sediments are composed of organisms that once lived near the surface of the sea. Because the number and types of these organisms change as the climate changes, the seafloor sediments they create provide a history of changes in climate. Clean, dry air is primarily ___ gas. Hint 1.
A variable component is an overall type of component that differs depending on things such as location or situation. The amount of the component does not affect its variability. Clean, dry air is composed of 78 percent nitrogen and 21 percent oxygen. Its two significant variable components are gases and particles.
Hint 1. A positive feedback mechanism is a scenario where the effects of a change reinforce the initial change. Global warming increases cloud cover, which traps heat on Earth, which increases global temperatures. Global warming melts sea ice, which decreases reflectivity and increases the amount of absorbed solar radiation.

According to the Milankovitch Theory, three cycles combine to affect the amount of solar heat that’s incident on the Earth’s surface: eccentricity, axial tilt, and precession. It is suggested that these variations then impact
Evidence from radiometric dating indicates that Earth is about 4.54 billion years old. During Earth's history life has evolved.
The majority of Earth's atmosphere is nitrogen , N2. The percentage of nitrogen in Earth's atmosphere remains constant as prescribed by the law of conservation of matter and because it is a reasonably non-reactive gas. Like carbon, nitrogen is cycled through Earth's spheres.
Like carbon, nitrogen is cycled through Earth's spheres. However, nitrogen can be converted into forms usable by plants and animals, either by lightning or bacteria. Once converted to usable forms, nitrogen is able to cycle the rest of the way through the ecosystem.
