An explosion occurs when the timescale for the energy release by some process is much shorter than the timescale on which a system can adjust to damp the energy release process. In the present day Sun, nuclear fusion is a very slow process: on average it takes many billion years for a proton to fuse with another. This timescale is quite temperature dependent, so you might have thought the centre of the Sun might heat up quickly, leading to a runaway "explosion". However, an increase in temperature leads to an increase in pressure that would expand the Sun, reducing the core density and temperature and decreasing the rate of nuclear fusion again. The timescale for the Sun to react in this way is just millions of years, so this acts like a thermostat that keeps the reactions under control.

Answer: The causes of ocean currents include wind, water temperature/salinity and natural disasters.
Explanation:
A current or circulation is the unified movement of water across the ocean. A Surface current affects the topmost layer of seawater and is defined by the direction of the wind while Deep Currents reach the sea floor though a combination of surface currents and landforms.
Water temperature and salinity cause currents by changing water density which in turn results in deep ocean currents circulating the seawater.
Other conditions that cause strong currents are storms and earthquakes which introduces particles into the seawater.
Answer:
Orange Groves are affected by the climate of the region. In the US, states such as Florida and Georgia are the biggest orange producers because of their climate. Also, oranges need good soil to grow, so dry soils are not suitable for growing oranges.
Nurseries are more "human controlled" than orange groves. A big human factor that plays a role in growing the food properly is temperature. If the temperature is too hot or cold, the plants may not grow properly and might even die. Also, many nurseries can control the humidity inside the nursery. Some plants require specific humidities to grow- and are vulnerable to a change in humidity.
Coffee plants require moist soil to be grown well. Thus, if the soil is too dry, the coffee plant may die. In other words, a coffee plant would grow much better in a farm, than a desert. Also, Coffee Plants require a high temperature, and that is why most of the world's coffee is grown in places like Africa and South America as they have hotter temperatures.
Coastal plains and Interior plains is in elevation. Coastal plains have low elevation and low relief. Interior plains have varied elevation and low relief. Coastal plains also lie along the shore while Interior plains are surrounded by other hopefully this helps
