To examine those differences, Hantson and his colleagues analyzed satellite data for 214 wildfires in California between 2012 and 2018.Human-caused fires typically spread about 1.83 kilometers per day, more than twice as fast as lightning-ignited burns,the team reports.The faster spreading fires also burned more violently and killed “double or triple” the trees as lightning-caused ones.
However, there is no fundamental difference in the chemistry of a human-caused blaze. “A fire is a fire” Hantson says. “It’s the surrounding things that matter.” Causes of fires ranging from improperly thrown cigarettes to sparking (冒火花) power lines could ignite a blaze on any given day, he says, while lightning strikes and dry thunderstorms only happen seasonally.
The researchers tracked meteorological data and found that human-caused fires were more likely to start on days with extreme weather conditions,and were more associated with drier,less-forested landscapes. This adds to scientists’ understanding of how humans are extending the fire season, says Nathan Mietkiewicz, an ecologist with the National Ecological Observation Network.
13. The author uses some data in paragraph 2 to show that ________.
A. wildfires are mostly caused by humans
B. most wildfires threaten people’s homes
C. wildfire is a part of California’s natural history

第24题图
(1)如图甲所示，将两个铅柱的底面削平、削干净，然后紧紧地压在一起，两铅柱就会结合起来，甚至下面吊一个砝码都不能把它们拉开，这个实验现象说明了 分子间有引力 。
(2)如图乙所示是小华模拟宇宙膨胀的实验，气球上的小圆点可以看成是宇宙中的天体，充气使气球不断膨胀时，任意两个小圆点之间的距离都在 增大 。在实际的观察中，天文学家哈勃发现星系在逐渐 远离 (选填“靠近”或“远离”)我们。
25．(18分)小明同学为了探究扩散问题而设计了如下一系列实验。
第25题图
(1)通过实验甲可发现 热 水中的墨水扩散得更快，这说明温度越高，分子热运动越 剧烈 。
(2)已知二氧化氮气体的密度大于空气的密度，你认为实验乙有什么不妥： 装空气的瓶子应放在上面，因为空气的密度小于二氧化氮的密度 。
